Stacy and I are going to Yosemite Valley in August. We have plans to hike up the back side of Halfdome. That is a 16 mile hike with 5000’ of elevation gain. Todays hike was only 9.6 miles with about 3400' elevation gain, but it is much higher than the Yosemity hike. Mt. Humphreys is the highest point in the state of Arizona (12,633').
