If Iron Mountain holds the crown as chief icon of self punishment for the Los Angeles hiking community, then Triplet Rocks is its weirder and sketchier crazy uncle. Part of that comes from the route itself, which at best feels like its in reverse, but is mostly going no discernible direction at all. Its first up and down two other mountains before following one of the most harrowing ridge lines in all of Southern California in a series of giant blocky AF bumps in a downhill roller coaster from hell before you then turn around and have to do it the harder way back up. And then its up and down those two other mountains again, accumulating heaps of gain. For someone who has designed around 500 routes in and around mountains since I was 5 years old, Triplet Rocks from the ACH via East Twin is maddeningly illogical and unsatisfying on topographical, logistical and experiential levels. And considering the difficulty involved, it seems downright masochistic.

There must, must be a better way, when the only way we know is so bad.

Solving the problem of Triplet Rocks for a half-sane route however is some advanced-level calculation…few have tried, all have failed.

I spent hours utilizing all of my favorite tools, looking at the target of Triplet Rocks from every possible angle like a Rubik’s cube in my hands. Every route I came up with felt stupid and dangerous, and hardly any improvement. Triplet Rocks is not just extraordinarily isolated by SG standards, and rugged by anyone’s standards, but so are the mountains and canyons surrounding it, too. Its an onion of navigational problems. I actually gave up about a year ago on this problem, throwing my hands in the air, and moving on to other projects.

Mathew has emerged as one of the most versatile and capable mountain explorers I know, and his stoke levels can be unmatched. When he told me he had Triplets in his sights for this year, that was enough to inspire me to revisit. And so after taking a long hot shower, going for a walk, eating a sandwich, a year later I returned, with a few new tools and another few months of experience, and this yielded a breakthrough.

You see, the primary things about the standard route to Triplets that piss me off the most is how much incredibly difficult gain you waste going up and back down again, and how the entire incoherent, jumbled and episodic route is ultimately, well, downhill. No good hike has a mountain peak destination thats freakin’ downhill. And not one with so much wasted hard AF gain. Not on my watch, at least.

So using a fundamental geomorphic truth, I took those two big flaws and flipped them completely upside down.

How would you hike to Triplet Rocks without ever having to go downhill to get there?

Thanks to gravity and water, from any point on earth this is ALWAYS possible. (Unless it is an endorheic basin, which do not exist in the San Gabriel Mountains.)

Following this principal, one is lead from Triplet Rocks, down a tributary to west fork of Bear Creek, to Bear Creek, and then the West Fork of the San Gabriel River, and a mile later you are at a trailhead parking lot on route 39. Its a long ways, but you get there. And Bear Creek even has a pseudo trail along it. Hot damn, now we’re getting somewhere!

But what’s the play from Bear Creek to Triplets? Follow the water, baby! My first impulse taking the Bear Creek West Fork to a tributary that would lead to this promising south ridge that leads right to the base of the third triplet. When a drop of water falls on a Triplet, this is where it goes.

Now, before we proceed, there is one other fundamental geomorphic truth of the San Gabriel Mountains I forgot to mention - when you have an idea for a route, always run it by Dima first. He’s probably already tried it. From a couple different directions. And if he failed, then you are going to fail too, and sooner.

And yup, sure enough:
viewtopic.php?t=8304

Damn.

But wait. That trip report is dated June 2020…

What far-reaching, historically cataclysmic event occurred in 2020 that disrupted our collective whole world?

The Bobcat Fire.

Dima didn’t have the Bobcat Fire when he had made his previous attempts. The West Fork watershed became a very different place after the Bobcat Fire, and has to have remained so 5 years later, no?

We don’t necessarily need riparian canyons, with their pretty but problematic waterfalls, in 2025. Because the Bobcat Fire burned all of our brush-related navigation problems to the ground. Climate change for the win!

The massive amounts of ongoing uplift in the Gabes meant Bear Creek flowed through a deep cliff-sided canyon, but where the west fork met the main fork, slope shading suggested a promising break in the cliffs.

Lets do this.

After various work and weather delays, Matthew and I set out at 6AM from the Azusa Canyon West parking lot at an elevation of 1,600 feet. (Just a little different than the 6,750 feet of the Waterman Ski slope!)

A quick road walk led us to Bear Creek, and its trail proved to be intermittent but lovely in the soft morning light between numerous crossings. I was prepared for this however, and was wearing an older pair of hiking boots I readily waded in as a dry set of new ones dangled from my pack. Mathew held out with rock hopping for a little while before giving up to take the plunge as well. If you travel the Bear Creek trail, be prepared to get wet up to nearly 3 feet with current water levels. Its feels pretty nice though. Not all that cold.

Our mythical target reveals itself in the distance.

As the canyon walls got higher, the pools got deeper, and we discovered Bear Creek is absolutely full of trout to an extent I've never seen before in the Gabes. Elongate figures darted away from us every time we stepped into the flow of water, which was often. The trail would come and go, and was very easy to lose and find again. Boulder hopping and stepping over burned trees is very common. Its not fast or easy going, but its very manageable and generally lovely.

At about 9am, 4.3 miles and 3 hours in, we reached the junction of the west fork at 2,170 feet. It was now time to stash the wet shoes and socks, and fill up on water. Another huge advantage to this lower south approach - you can filter your fill of water 4.3 miles into the route. East Twin doesn't offer that!

Now the adventure was to go up a notch. The big question now was how high and thick the brush would be out of the canyon. This would make or break the route, as we knew it was impassable before September of 2020.

An extremely well-trodden game trail lead us just as hoped out of the canyon. It was no wonder the trail existed, as it was cliffs for more than a mile in either direction surrounding it, and animals gotta drink. In my excitement I completely overshot the bench above the canyon we were intending to travel north upon, and charged up an additional slope. This made Mathew eager to take the higher bump-hopping route over point 3329 that I had created earlier (v3) while I had my heart set on the bench route (v4) with less cumulative gain. I truck a compromise between them, and we began navigating this new world above the creek canyon, pushing a small herd of deer before us in the bright morning sunlight. And most importantly - the brush was reasonable!!!! Most of the time shoulder or waist high, with bare ground pockets between the scrub oak. Hurray!!!! This route was working!!!

Mathew still wanted the higher route, and as I discovered my hopefully flat-ish bench had somewhat steeper and deeper ravines than the slope angle shading may have led one to believe, I started to agree more with him. We ended up taking adjacent ridge lines up point 3329, about 0.16 away from each other, but able to keep ourselves within view and earshot. I knew in an area this remote and rugged its bad news bears to get separated.

Along the steep climb to 3329, I got this excellent and extremely rare view of the south face of triplet rocks, with this one-of-kind giant gash in the granite face. Its unlike anything else I've seen....that gash would be one hell of a canyoneering route to come down. Is this Taco's Zebra wall?

I met Mathew on 3329, with a spectacular view of the whole remote area. I'm not sure how many people have ever bagged 3329, but its got to be nearly no one. Could it be one of the most remote, and pre Bobcat at least, difficult to reach benchmark in the Gabes? Curious if anyone knows of anyone who has been there. Check out this rad view it presented of all 3 Mermaids:

Coming down the north side of 3329 we began encountering the dreaded POODLE DOG BUSH. And oh my, did we ever.
2025-05-14 11.11.59.jpg

.
.
And as we began to ascend the ridge that would eventually deliver us to the Triplets, it kept getting worse.
2025-05-14 11.13.04.jpg
.
.
.
The leaves and stalks were brushing our clothing, and we could smell the aroma strongly in the air. This was my first time encountering this storied plant, and after a couple nasty poison oak experiences, I was starting to feel pretty nervous. Ready for brush warfare, I was thankfully covered head to toe with gloves, gaiters and the like, but still I knew people described Poodle Dog as "poison oak on steroids" so I was not feeling super confident charging through it all. Mathew miraculously had just passed into a little bit of service, so took advantage by calling Sean to ask for advice. Sean said we should basically burn our clothes and clear our calendars for the next 4 weeks. That was enough for us to bail then and there, at 5.8 miles into the hike at 3,5000 ft elevation and 11:30AM. It was a disappointment, as we were *just* starting to travel this south ridge we were both fully stoked to scramble along, and done so much preparation for, and still had a couple hours before our turnaround time. And Triplets were right there staring down at us past the Seussian poodle dog leaves peacefully swaying in the mountain breeze.

Poodle Dog is a strangely abstract obstacle, because in the moment its actually no obstacle at all. Its just a pretty flower. You have to intellectualize the *possible* consequences days later. Difficult pill to swallow when you got a little summit fever in you.

Fire taketh brush, giveth Poodle Dog. I came into this expedition knowing our odds of actually summiting was less than 50/50 chance. I thought probably brush, cliffs or time would be what got us, but Triplets cooked up a surprise with the Poodle Dog. I hadn’t thought of that one! Well played, Triplets.
.
.
.
We followed my v3 route back down up and over 3329 again, being super cautious with poodle dog. I’ve never been so happy to see shrub oak in my life then when shimmying around the PD. We pushed through the brush and stumbled down the crumbling slopes until we had made it back to Bear Creek and our waiting shoes and socks, and took the opportunity to do lunch in the dappled shade, of which there was absolutely none when out of the creek canyon. I ate Sardines while watching the trout dart about the beautiful pools, now bright and cheery in the midday sun.

Before the Bobcat fire Bear Creek was probably shaded in the middle of a late spring day, but now that is not the case, and the majority of our trek back down the creek was in the warm, breezy sun.

At least there weren’t any skin-irritating plants along the creek…. Oh wait.
2025-05-14 13.58.29.jpg

.

Mathew started getting it from all directions, with a couple falls into the water, attacked by Yellowjackets while trying to eat some goo, and blasted by stinging nettles. He can tell you more about those episodes.

We made it back to the car around 4pm, driving back into Los Angeles in our underpants as our contaminated clothing sat in poisoned piles in the trunk.

I am *very* thankful to say that a little over 48 hours later, I have only one lone little blister on my right ring finger. Here’s hoping…. 🤞

In conclusion, I’ve never had a target as challenging as Triplets. I understand now first hand why it has the reputation it does. The Poodle Dog presents an exotic problem I’m not sure I fully understand how to combat. The trouble is our window for brush height is in the process of closing…I think we have maybe 3 more years before it starts becoming enough of a problem to make this route no longer viable. There may be 3 more years of Poodle Dog which fill that window. Is there any opening in between? Is being full covered in a hazmat suit of some kind make it possible to get through the PD? Is there another possible route that could circumvent the poodle dog? I do know we are freaking close. The exposure of the south ridge above where we turned around remains the only open question, but the slope angle shading suggests its possible, if a couple spots on the edge. I’m not exactly sure what the next attempt should look like exactly, but I do think an overnight camp is probably involved.

I need more time to process before deciding what comes next, but Triplets - my hat comes off to you. You earn your status.

I wanted to write my own report for this hike!

Triplets has been in my scope for many years at this point and ever since I started biking and hiking super regularly, I’ve felt ready to take on the challenge of reaching it. Nate proposing to reach it from the south got me even more excited since it’s never been done before, even after many attempts by legendary mountain goat Dima. Nate’s proposed route would bring us from the west fork parking lot all the way to the peak with only uphill travel. The idea that this would even be possible was from my reconnaissance from East Mermaid last December, where I noticed the south face and ridges totally free of dense brush. The ascent up East Mermaid through it’s ridge showed the ease of moving through the brush which gave us high hopes for the southern approach of Triplets.

We utilized some of my favorite tools such as CalTopo & secret aerial imagery sites to plan out very specific maneuvers around the hardest and rockiest sections of the ridge. Nate used slope angle shading to choose the specific “fingers” of the ridges to ascend on. From the computer screen, everything looks relatively doable!

After many planning roadblocks with weather or work getting in the way, Nate and I finalized a day. We met at my place at 5:30am sharp, got some Starbucks coffees and headed up to the trailhead. Around here “34°14'03.0"N 117°50'47.7"W” we got a beautiful view of the triplets just getting bits of the morning sun to light it up which got me both very nervous and very excited to start this hike. That view is never going away and will be there for every other attempt from the south as a reminder of how far and high we are gonna go.

The strategy I had in order to conserve energy and time was to start the hike with 1 full nalgene and fill up as I go. We also decided to wade through all the creek crossings since once we got closer to the fork, it would be necessary to get wet. Bringing an extra pair of shoes and socks was important for this plan to work and I will be doing it again next time.

Bear creek is becoming one of my favorite places to hike through due to it’s vast greenery, trout filled pools, birds, and life in general. Some of the scenes Nate and I saw well past the main trail camp were spectacular to see. Moving through all this while being in one of the most remote areas I’ve traveled through was incredible and I highly recommend the visit. It was great at first (foreshadowing chaos) to see so much wildlife in the canyon like bees buzzing, birds chirping, and trout everywhere and it made me want to possible backpack back there in the future.

We reached the fork of west bear creek and the main branch at 8:45am to find an easy path out of the canyon and onto the first ridge we’d take. We changed out of our wet shoes and into our approach shoes to then begin the steep stuff. Nate and I were aiming for a path that would keep us low at first, then bend west to the main ridge of triplets in order to not go up and down on a couple up bumps. The route looked good on the maps but the slope angle shading did not show the deep rocky narrow gullies that we would have to cross. I split briefly from Nate who decided to cross one of those gullies and we managed to stay within seeing distance until we reconvened on the first bump. I missed the opportunity to take a picture but the damage of the Bobcat fire allowed us to stand out very well amongst the wilderness around us. Also, the view of East Mermaid, Middle Mermaid, and West Mermaid lined up was amazing!
Mermaids.jpg
We descended down the bump to find ourselves surrounded by lush wildflowers and buzzing bees. Then came the poodle bush…
poodletriplet.jpg
The ridge in front of us was covered in it and our excitement seeing triplets just up ahead allowed us to find narrow paths between the brush to hopefully avoid direct skin contact. We only got 768ft from the lush flowers to dense poodle where we decided to turn back. I had a sliver of cell reception so I called up Sean for some poodle advice. We definitely brushed against some of the poodle bush so we had to make sure not to make skin contact with our clothes for the remainder of the hike. This unfortunately was very hard not to do. We began descending the ridge while trying to avoid poodle and poison oak as much as possible, while still maintaining the highest of stoke for the distance we were able to reach. Seeing triplets that close was amazing as well as knowing that we were getting a very unique view of the peak from below that only a few have been able to witness. I took tons of pictures of the rock faces that I hope to climb one day with Taco or others and I became excited to return, regardless of how badly I might get rashes later.

We returned to the creek and began the hike back to the car, which was the worst time I’ve had hiking. Everything was fine until we reached this specific point: 34°15'57.6"N 117°53'38.5"W where we stopped to simply eat some sodium and caffeine filled gu. This was an innocent act where we just chugged water and rested in the shade. Immediately, we were swarmed by yellow jackets who decided to wreak havoc on both of us by leaving me with 2 stings on the forehead and 1 stig to Nate’s eyebrow. I was so scared, I removed my sun hoodie (which meant that I was shirtless and made contact with poodle oil) and ran away as fast as I could, ditching all my gear. The pain we experienced while doing nothing offensive to the bees was not right. I begged Nate to make a run for it and grab my stuff since I had no shirt on and he did. I have the video of it all with Nate being swift and scared saving the day. Not even 25 minutes later, I got nettled by some stinging nettle which was a first. Then a few minutes after that, I took a big fall in the creek which broke one of my trekking poles. I had pain on my face, arm, legs, and side, and especially in my heart and stoke.

Hey rock climbers who don't believe that theres any climbing in LA county and always feel forced to not check out the gabes, here is your rock

I don’t know what else to write… Looking back at the hike days later, it was humbling and one of the best hikes I’ve done. Triplets is a hard AF peak to reach. We thought doing it from the south post Bobcat fire would be easier but the peak and it’s canyon wanted it to be hard and mentally testing. Hell yeah, go explore!

I’d like to share my packing list for this and what I’d like to bring for next time.
  • Approach shoes
    Burrito
    Trail mix
    Apples
    Hiking shoes for water crossings
    Extra socks
    Headlamp
    Extra AAA batteries for headlamp
    Chalk in a plastic bag
    Sawyer
    3 Nalgenes
    Trekking poles
    First aid kit
    Sunglasses
    External battery pack
    Eispiraten flag
    10ft webbing
    Electrolytes
    Hat
Things I would add for next time would me the following
  • Small binoculars (for scouting other fingers of ridges)
    Gloves
    A camera

Sorry to hear a about the unfortunate events that took place trying to summit Triplet Rocks.

It sounds like Matthew got the worst of it. I've been stung by Yellow Jackets on the neck and they are vicious.

I actually know of three groups who made it to Triplet Rocks before the Bobcat fire. I know they did not follow the same route you did.

Anyways, nice try.

I'm just curious as to why you didn't think to bring loppers or a machete just in case?

When we attempted TR years ago the bushwacking sucked.

Well that was an unexpected obstacle to force this mission to be abandoned! Any way to tell where the poodledog groves are? The last time _kick_rocks_ went to the Triplets, he said the ridge-top was covered with poodle-dog. He took the ridge from East Twin. Presumably most of the area is covered. Any way to get a sense of which areas are affected without actually going over there? Any terrain they like in particular?

This is a really good question. Loppers, machete, etc on conventional brush can be very useful. But Poodle Dog Bush is not conventional brush. I am worried cutting the poodle dog might cause as many problems as it solves if the flowers are falling over onto you when you cut them down. Maybe if you had some crazy super long-handled pair of loppers?

Is there ANY known effective strategy for getting through these plants? I would love to know if there is.

Internet says granite slopes between 3,300 and 7,500 feet.

Every slope at those elevations in the Gabes is granitic, so that does you no good.

those elevations totally check out, because we did not encounter any poodle dog until starting right around 3,300 feet, before getting turned around at 3,500 because it had become so widespread and thick.

What a weird, abstract, exotic problem.

I know of a group that has hiked Triplet this year via the Twin Peaks Ridge so it is manageable as far as the poodle dog in that direction.

This was a valiant attempt and great fun to read. Bravo!!

I've also studied Triplets many times over the years. If I ever made an attempt, I would try Dima and Headsizeburrito's canyon route OR that super steep drop from highway 39 that intersects that route at the end.

You guys had some bad luck with the yellow jackets. They are one of the meanest wasp species, happy to sting you without provocation. I'm glad you could retrieve all the gear and that everyone made it out (mostly) in one piece.

The one time I pushed through dense poodle dog was on Santa Paula Peak. The old route goes through private property and the only legal way there now is the canyon route. Near the top, there was no way to avoid the poodle dog. I got the peak, then suffered two weeks of rashes. It was the price of admission.

If you stayed completely covered, maybe you could take an extra set of clothes and gloves (or two) and bundle up the poisoned ones in a garbage bag on the way back.

Hey, what if you used those cheap plastic rain ponchos to protect yourself while pushing through the poodle dog?

About $2 each and easily disposable.

I gotta give this south ridge a full-send before I start considering those alternatives.

So far, I'm preferring my current experience with Poodle to poison oak. My rashes are more minor and bother me less if I leave them alone. But of course I think I just had way less exposure on this trip than I had with poison oak last summer in Bee Canyon. That was REALLY bad. I was wearing a T shirt for absolutely no good reason.

Sean used something like this for trail work in poison oak once. I think its my plan for next time, no joke!!!
