We are most fortunate to have Art Wahl follow his May 20 lecture on the San Rafael Mountains mélange with a hands-on visit to representative sites in our backcountry.  We will venture into the Mesozoic subduction zone that is world famous for its mélanges that contain high pressure-low temperature blueschist. Detailed instructions for the time and place of the starting point of the auto caravan will be provided to the registrants.
