Explorers Club Activity Chairs

Matt Barnes (
Mountain Biking Chair

Matt is a mountain biker, backcountry skier and trail runner. Favorite trips include the Zion grand traverse, Kilimanjaro via the western breach, Roger's Pass, Matterhorn Canyon in Yosemite and the winter mountaineer's route on Mt. Whitney. He is an Adirondack 46'er, Eagle Scout and ECP mountaineering school grad.


Ben Towne (

I got started hiking in my home state of New Hampshire, a state with enough amazing natural beauty to get me hooked.  I've climbed a number of the state's peaks including the *real* Mt. Washington, which is much more challenging than Pittsburgh's old Coal Hill.  I enjoy hiking in PA as well as other states and countries, including a 7-month travel and backpacking trip in Europe a few years back. If there's somewhere you want to go (see suggestions above) just put out a note to explorers-hiking and let's make it happen!
