Calcite Springs
Calcite Springs emerges at 201 degrees Fahrenheit along the walls of the Grand Canyon of the Yellowstone, where superheated water heats 163.5 degrees above ambient temperatures. Located at 6,305 feet elevation and 574 meters from the Northeast Entrance Road, this thermal system requires a short walk to reach viewing areas overlooking the canyon's northern reaches.
The springs flow from steep canyon walls carved by the Yellowstone River, where thermal vents stain the rock face with mineral deposits that inspired the feature's name. At this elevation, the terrain receives 26.5 inches of precipitation and 127 inches of snow annually. The surrounding landscape transitions between lodgepole pine forest and open thermal zones, with the Lamar Valley's wildlife-rich grasslands extending to the northeast.
Tower Fall Campground, just 2.1 kilometers away, provides the closest reservable camping with access to wildlife viewing in the nearby Lamar Valley. The short walk to viewing areas requires attention to trail conditions, which can be muddy or icy depending on season. Visit May through September for optimal road access and trail conditions; winter brings deep snow and road closures to this section of the park.
Documentation of these springs dates to early Yellowstone surveys, when geologists cataloging the park's thermal features noted the calcite and other carbonate minerals precipitating from the hot waters. The springs have remained in a relatively stable state since systematic observations began in the 1870s, with no recorded major eruption or significant flow changes in modern records.
