Thacher Park Project Day

A day of ridgewalking, locating, and mapping caves in Thacher Park. If you don't know how to survey a cave, this could be a good chance to learn by working with an experienced team.

Saturday, 9/14/13, 9 AM at the Hop Field parking area. Thom will be there most of the morning handing out assignments if you're running late.

Bring water and a lunch.
