I was looking at aerial imagery of the San Gabriels on Friday, and spotted something so compelling, I just had to go check it out in person. The imagery showed the tail of a US airforce transport plane (C-46A #41-12363) that crashed between the Devil's Punchbowl and Mt. Williamson in 1944 (in February or March or June, depending on what you read).

So, early in the morning on Saturday, Sean and I arrived at the Devil's Punchbowl, and started walking. We took the trail towards the Devil's Chair, but split off where it crossed Punchbowl Creek, following the creekbed upstream. Initially there's a use trail, but this becomes more and more faint as you ascend. The canyon is actually really nice. There's currently a good flow through it, and it's a pleasant (and steep) boulder hop. Looks like this from the bottom:

Image

We're going to not-quite-the-top of the main ridge in the photo. As you ascend, you quickly start seeing scattered pieces of the airplane. Most are generic parts of the body: aluminum sheets held together with rivets, but some are more interesting. Relatively close to the main trail crossing is this wheel:

Image

We ascended the creek, and went right at the first major split. Soon after, we hit first waterfall.

Image

It's nice! There's a bypass on the climber's right. We kept climbing and would encounter more wreckage pieces regularly. We went left at the next canyon split, and immediately hit another waterfall. Sean was unimpressed

Image

but it really is nice.

Image

There's a bypass on the left, complete with a faint use trail. This use trail navigated a brushy area, and seemed to lead upwards on the ridge, instead of dropping back down into the canyon. This is the ridge that held the wreckage, according to the imagery, so we just kept climbing. The brush soon subsided, but that isn't the problem here, which is that this area is STEEP.

Image

The terrain here rises towards a main ridge at ~8000ft. The South side of this ridge contains the C119 wreckage, which is also an off-trail scramble, but a much safer one. The North side of the ridge (which we're ascending) is steep scree for the most part. The minor ridges between the scree chutes are made of unstable granite, so they're arguably more dangerous than the chutes.

Image

Image

Eventually, we came up on the tail:

Image

This thing is HUGE. It's on a very loose slope, and the only thing holding it up is the tree that impaled it on impact. The tree is long dead, and this whole thing will slide down into the canyon eventually.

Image

The South side of the tail still has the green paint

Image

Did I mention this thing is huge? You can climb inside it, and it's a nice shaded spot to eat lunch. You can also examine the life raft diagram

Image

or read the scrawlings left by previous visitors

Image

We attempted a timed group photo. It took me a few tries to successfully scramble down from the camera to the tail in the 10 seconds my camera gave me, but eventually I made it in time.

Image

We were still about 1000ft below the main ridge. Above, there were a few more areas that the aerial imagery indicated could contain wreckage. I climbed up the sketchy terrain, and found some more stuff, just a little bit below the ridge. The biggest pieces were this fuselage-looking thing:

Image

and these wing-looking things:

Image

Image

Note the number on the wing. This isn't the C-46A #41-12363, but rather it's the C119 #53-3195 that lies mostly on the other side of the ridge. The C119 must have clipped the ridge traveling South, and left debris on both sides. While the C-46A impacted lower, and ALL of its debris is on the North side of the ridge. It is interesting that the two debris gullies are directly opposite the ridge from each other. It is also interesting that other than the tail, there were relatively few big pieces of the C-46A. It could have broken up into a large number of small pieces, or much of it could be buried in the scree or in the canyon below.

I topped out on the ridge among the scattered C119 debris I saw the last time, enjoyed a few minutes of flat ground, and then descended back down towards the desert. My camera ran out of juice at this point, so all the remaining photos are Sean's. Descending the scree fields was significantly easier than climbing up. On the descent we faithfully followed the gullies from the tail, so we'd walk by everything that slid down the hill. This was the biggest non-tail piece we found:

Image

It was half-buried already, and the scree we pushed down on our descent buried it a bit more. We dropped down into the canyon, and walked in the main channel, hoping to see more stuff. I was hoping to see some bighorn, and then there they were

Image

I also wanted to see an engine, and then there it was, half buried in the dirt on the side of the canyon, one prop blade still attached:

Image

Image

Then I wanted to see a landing gear, and bam! There it was, complete with wheel and tire, also buried in the dirt on the side of the main channel:

Image

Image

Other things buried in the canyon were a loose propeller blade, and this thing:

Image

This was all above the second waterfall, where we split off on the way up.

Then I wanted to be done, and this wish came true also, albeit hours later.

This was a great trip. The debris is scattered over a massive area, spanning over 1000ft of elevation. Distance-wise, it's relatively close to the main trails, but these are tough miles, and took a while.

I visited the upper wreck (prolly C119?) many years back. Rather than canyon thrashing up, I took the western ridge. Go up the remaining road from the Devil's Chair/Burkhart split, and a use trail starts up the ridge. The trail is good until a prominent saddle (~7200'). Then, it's a 'conglomerate knife edge with a buckthorn toupee' nightmare for a bit, then mellow the rest of the way. Loop the headwall and start descending the eastern ridge, and that's where I found a chunk of fuselage.

Interesting route. Were you looking for anything in particular on that section of the ridge, or just checking it out? This crash site is spread over a large area, so you pretty much have to transit the steep sections to see all of it. Getting to the top is straightforward-ish from the ACH, and the bottom is accessible via the creekbed. Doing both requires climbs.

I was trying to get to Williamson. By the time I reached the Punchbowl headwall, I realized I had the flu, so bailed down the eastern ridge. That's when I found it.

This is what the terrain on the western ridge looked like as I neared the headwall:

Hi Dima-came across this newspaper article while researching John Robinson’s files at USC; do you think it’s the same crash? Location differs and the date of the article is 11/1944. I am scheduled to go back there next week and will copy whole article.

Thanks for the article, Paul. This is a different one. Macha talks about it on page 53 of his book:

https://books.google.com/books?id=nhR3C ... &q&f=false

I haven't gone up there yet, but that could be fun. According to that book, the big stuff was pulled out for salvage, but lots of small chunks remain. Every time I try to find crash reports in an old newspaper, I always have to make sure to find the report about the correct accident: it seems like there were multiple crashes being reported-on each day.

Okie-doke; I'll copy the whole article and get it to you.

What are these "John Robinson files"? It's physical notes/newspaper clippings and such that Robinson collected through the years? Anything particularly noteworthy?

Files containing written material, photos and maps that Robinson used in creating his histories, trail guides, etc., about 10 bankers boxes worth. For me as a trail historian it is fairly valuable stuff. For example, based on "outake" photos in the archive I am close to being able to produce a credible map of the Oak Wilde resort in the 1930s.

Update: I think the item described above as "this thing" is a radar unit.
