Doug Walker, a Seattle-area tech entrepreneur, conservationist, and philanthropist who helped launch donor network Social Venture Partners, was found dead Friday after a hiking accident, The Seattle Times reports.
Mr. Walker, 65, had been reported missing Thursday after failing to return from a snowshoe trek on Granite Mountain, a peak in the Cascade Range friends said he had climbed at least 200 times. King County, Wash., authorities said he was probably caught in an avalanche near the top of the mountain.
A South Carolina native who relocated to attend the University of Washington, Mr. Walker was a founder of software firm WRQ and a director of outdoor retailer REI. Along with co-founding Social Venture Partners, he served on or headed the boards of numerous conservation and other charities, including the Wilderness Society, the Seattle Parks Foundation, and the Fred Hutchinson Cancer Research Center.
