I went backpacking into the Siskiyou Wilderness (in northern CA) the first week of July. Spent 3 nights in the mid-section of the wilderness; backpacked from end of northern portion of the GO-road (Boundary Trailhead) down to Elk Valley. This trail is north of the Blue Creek drainage. Elk Valley is where we camped and is the beginning of Blue Creek. After exiting, we drove to the northern end of the Siskiyou Wilderness and spent another 3 nights. One night at Sanger Lake and then we backpacked into Youngs Valley. Youngs Valley is where Clear Creek starts and drains south.
We saw plenty of deer on the meadows. We did not see or hear any bear or bigfoot. The wild berries were not out yet.
We did find what appeared to be 2 footprints on the Boundary Trail on the way back. They looked like old footprints that were imprinted when the terrain was wet and muddy. One print is human size but could be a double print from a bear or just random formation. The other print is small (like from a toddler) and gives the appearance of showing the toes pushing the mud out. They were not very good and I am not claiming they are from BF but I took pictures anyway in order to document. I doubt that children will walk barefoot where we were. The map below shows where the footprints were found relative to TH entrance and other key places in Siskiyous (like PGF site and Louse camp).
