OverviewEastern Sierra. It apparently gets it's name because of it's white tefra covered slopes and when seen from the air it is shaped like a giant wing.
MoapaPk has added: "Perhaps the most amazing thing about White Wing is the forest of dead trees on top killed by an eruption of Obsidian Dome 600 years before."
The lower slopes are mostly forested and the upper third is generally sandy. I would imagine that it is mistaken for Mammoth Mountain at times. I know that was the case with me the first few times I saw it while driving by on Hwy. 395.
There is an outstanding panorama of the Mammoth Lakes High Sierra from the top. The view stretches from Mammoth Mountain all the way to Mount Morrison and beyond.
From the northeast: From the junction of Hwy. 203 go north 11 miles on Hwy. 395 to an unnamed road going southwest (passable to all cars). Turn left on the road as it curves to the south (at 1 mile) and meets a dirt road at 1.5 miles. Go south on this road 1.2 miles until it crosses Glass Creek and park at 8,100'. Hike along Glass Creek and up the northeast slope of the mountain 1.2 miles to the rocky northeast summit at 9,901'. This is a considerably sandy slog but not too bad. Continue southwest over the middle hump another mile to the main summit.
Lower Deadman Campground: Same approach as the upper only 1 tenth mile to the south.
White Wing Campground: Take the Deadman Road 1.2 miles to the fork and go right then another immediate right to the campground at .2 miles.
I noticed people camping at the parking area for the northeast approach from Glass Creek when I hiked the northeast summit but there were no established facilities.
