OK, now I'm on the correct trail to Keystone Spring!

Hiking down Woods Wash, I take a look around the historic site and start hiking up an unnamed side canyon
I come across an animal trail, and follow it when possible for the best route up the canyon. Due to obstructions here and there, it's easy to lose it occasionally, only to find it again shortly thereafter. There's Tortoise Shell Mountain in the background.
