I did Rattlesnake as the typical loop from Shoemaker Canyon Rd, ascended the south ridge and descending the east ridge. The south ridge route is straightforward and actually very pleasant. I made my way quickly up to the summit. The east ridge is a much rougher route - overgrown, steep, loose, and ambiguous. I've heard this peak described as "Little Iron," and this side of the mountain earns that title.

On the way down, I guess I ripped open my side pocket, because when I got to the tunnel on Shoemaker Canyon Rd. and went to take a picture, I discovered my phone was gone! I guess I ripped the pocket and dropped the phone while bushwhacking through chapparal and/or sliding down steep lose dirt. I was completely prepared to re-climbing the mountain to find my phone, but luckily recovered it in the middle of the trail only a tenth of a mile back. The tunnels on Shoemaker Canyon Rd. are totally sweet and worth a visit.

After this, I went to hike Smith Mountain to make a full day in the San Gabriel River Basin.
