Boskoff is the only American woman with verifiable summits of six, 8000m peaks (three additional 8000m expeditions were forced to turn back before reaching the summit). She navigated Mount Everest, Shishapangma, Gasherbrum II, Cho Oyu, Lhotse and Broad Peak. She made winter ascents of Mount Angor and Mount Kilimanjaro and climbed Mont Blanc and the Matterhorn. Boskoff mainly eschewed corporate sponsorship for expeditions, choosing to climb without the pressure of media and corporate attention. In her later years, she turned her climbing efforts to first ascents of lower, lesser-known peaks in Asia.
