I am a member of the MIT Outing Club. Although I can't go hiking as often as I'd like, I take every oportunity. Here are some pictures from couple of recent hikes..
These pictures are from the MITOC rock climbing class in the Rattle Snake Mountains.
I'm in the upper right hand side
Couple of pictures from the Rainbow Basin archaeological site in Barstow California. In the second one, you can clearly see the rock layers from different archaeological eras.
