FOR TWENTY YEARS David has directed, instructed institutional wilderness field programs and organized personal exploratory expeditions all over the world.  He spends around a hundred nights a year under sky or fly and over the decades has logged thousands of days in wilderness.  Some geographic highlights include:

            The Sierra Nevada of California

            The American Southwest

            The Swiss Alps                                                                               

            The Nepal Himalaya

            The Highlands of Scotland

            The Southern Alps, New Zealand

            Alaska and the Yukon Territory
