Little SG 9133' (HPS #28) and Wilshire Mountain 8832' (HPS #36) are two of many peaks on Yucaipa ridge. Little SG is also one of two peaks I failed last year (the other was Palo Verde and that wrong was righted). Temps were warm, and I doubted any lingering show was hiding in the shadows of the northern slopes, but I took microspikes just in case. I got my online day hike permit and set out from the Vivian Creek trailhead around 6:30 AM. There were only two parking spots open when I arrived. I took the same gully shortcut as my first trip and transitioned to the drainage feeding Mill Creek. Instead of frozen puddles, a trickle of water was flowing. I left the drainage and faced the steep (45-50%), loose dirt gully. I ascended using trees and brush to assist. Even large rocks on the slope were mostly unstable and I didn't trust them. Above the first gully, the route to the ridge over a boulder field was well marked with cairns. Once on the ridge, there was a use trail that ran mostly along the south side toward Wanat Peak.

Moving along the ridge toward Wanat Peak

During the side hill traverse under Wanat Peak, I lost the use trail. There were three gullies to cross to reach the saddle below Little San Gorgonio. I went too high on the traverse which made it more difficult and dangerous with no upside. I did a little better on the way back, but was never sure I was on the use trail. The final march up the burned ridge was on a well defined use trail and a relief. Views were splendid. Both San Gorgonio and San Jacinto loomed large. There were no marks. I found a pair of register cans, but no register inside. It needs a new register. After some photos, I felt like I had enough motivation and provisions to go for Wilshire Mountain.

Hilarious AarJay humor on a register can

I started along the ridge to Wilshire, reaching an unnamed bump with radio towers and scientific equipment. There was a sign noting the land and equipment were private property to discourage vandalism. The unnamed bump was the terminus of a rough bulldozed road. Since Wilshire was the next big bump, I stayed on top of the ridge, crossing the road a few times. I didn't have a precise GPS location for Wilshire, but eventually, I stumbled on a clearing with a couple of registers. The original nested cans had been smashed and were hard to open. It held a couple of old registers. A newer can had a fresh register going back to 2023. An 8' class 2 boulder was the high point. No real views from Wilshire since it was surrounded by trees. It was about 400' up getting back to Little SG. The descent went slowly. I took a couple of unplanned butt slides on the slope, triggering impressive rock slides below. When I got back to the stream, I took off my boots to cool my feet in the water. It was a welcome respite from the warm afternoon sun. I cruised back on the same route, feeling worked. It was a difficult, but manageable and satisfying hike.

Thanks for posting! I usually hear of people ascending that ridge from the North (Mill Creek) but not from the South (the populated areas). Is it far steeper on the South side?

I'm not sure it is steeper, but it's steep. First mile gain -> 700', second mile -> 1800'.

Good report. That rock gully looks like a lot of work, both ways.

Not too bad. I think it looks worse than it is. The route stays in it for about a half mile each way.

I think the most difficult and dangerous part is between Little San Gorgonio and Galena. From Wilshire down, there is a dirt road that goes near most of the peaks. I still need to hike the lower part of the ridge.
