Cascading from the 590,000 year old Canyon Rhyolite lava flow, Lower Yellowstone Falls is the largest volume waterfall in the Rocky Mountains and are 308 feet high, or nearly twice as high as Niagara Falls. The volume of water flowing over Lower Yellowstone Falls can vary from 680 cu ft/s in the autumn, to 8,400 cu ft/s at peak runoff in late springtime. The flow rate of Lower Yellowstone Falls is much less than that of Niagara Falls, as the Yellowstone River is only 70 feet at the point at which it goes over the lower falls. Wikipedia
Shrubby Cinquefoil (Dasiphora fruticosa) thrives in dry to wet areas and rocky regions to open meadows. This deciduous shrub can reach a height of 3 to 4 feet. The leaves are small and compound, with fine hairs. The bright yellow flowers can be found from April to July. When the plant is mature, the bark becomes flaky, papery and thin. This hardy plant is often used as an ornamental shrub. It's a great solution to erosion and can be used to stabilize slopes. NPS
The geothermal areas of Yellowstone National Park include several geyser basins as well as other geothermal features such as hot springs, mud pots, and fumaroles. The number of thermal features in Yellowstone is estimated at 10,000. Although famous large geysers like Old Faithful are part of the total, most of Yellowstone's geysers are small, erupting to only a foot or two. The hydrothermal system that supplies the geysers with hot water sits within an ancient active caldera. Many of the thermal features in Yellowstone build up sinter, geyserite, or travertine deposits around and within them. Wikipedia
