In spring, as soon as the snow melts, it is not uncommon to see large areas of the meadows flooded and practically transformed into lakes.
Plant species composition changes across the meadows with different landforms, landscape positions, and summer water-table depths.
The main herbaceous wet meadow species include alpine aster, nearly-black sedge, King's ricegrass, western bistort, Breweri's reed grass, and dwarf bilberry.
[4] Tuolumne Meadows has a good view of the Cathedral Range and Unicorn Peak (to the south), Lembert Dome, and Mount Dana (to the east).
Downstream (flowing to the right (western) side of the image), the Tuolumne River cascades over Waterwheel Falls near Glen Aulin, eventually pooling at Hetch Hetchy Reservoir.
Many backcountry hiking and backpacking trails start in Tuolumne Meadows including the primary route to summit Mount Lyell, the highest peak in Yosemite National Park.
These trails are serviced by the Tuolumne Meadows shuttle bus, typically from June to September, though the dates are subject to change due to weather.
