Darby Field and the "First" Ascent of Mount Washington

For more than 200 years historians believed that Darby Field made the first climb up Mount Washington in 1642. However, in the last several decades, questions have emerged about his use of Native American guides, about the likelihood of prior ascents by Native Americans, about the route Field may have followed on the mountain, and about whether Field actually made the ascent as claimed. Allen Koop examines how historians reconstruct the "truth" when given scant, vague, and even contradictory evidence.
