  1. Dave, I will be leading a Friends of Mineralogy collecting trip at Washington Pass on that weekend of Aug 9-11. You will see some folks at MP 164, 165, 166, and 167. I usually take some folks up to the base of Liberty Bell to collect in the talus slope on Sunday. We camp at Klipchuck on Friday and Saturday. Wes

  2. Maybe I missed it, but could not find the total fees for the “Cross Section Through the Crust” trip. Does Accomodation cover everything? And – will there be walking tours, or only driving? Thanks, Kitty King
