There was some discussion about yesterday's post regarding where the picture was taken. Mom called one of dad's Fish and Game friends and found out it was taken on Jacks Creek near Bruneau.
I did a bit of research and discovered this site which has some great pictures in case you want to try this hike.
It describes the area as "A spectacular hike into a remote canyon. Extensive rhyolite and the opportunity to observe raptors, bighorn sheep, and pronghorn antelope."
It looks to me like the actual trail stays up on the top of the canyon, but from the picture, dad must have hiked down into the bottom. Looks like a wonderful day trip, but probably infested with rattlers! However, I can certainly see why dad loved it.
