In this #DavDispatch from Day 10 of the #VolcanoTour, Dav shows clear signs of fatigue as he crests the summit of Mt. Adams after having climbed 8.5 mi. and 9,000 vertical feet in 7.5 hours. With 4 volcanoes yet to go, including 14,411' Mt. Rainier, the Volcano Tour promises to push Dav and the other athletes to their limits.
