When you drive by an overlook in Yellowstone National Park, it pays to stop. A short walk from a turnout on Grand Loop Road just north of Tower Fall brings travelers to Calcite Springs Overlook, perched on a bluff above the narrowest section of the Grand Canyon of Yellowstone. The mesmerizing northward view puts a rugged section of the Yellowstone River on display, accented by bleached cliffs and steam venting hydrothermal springs. The loop to the viewing platform is a quarter mile long, and well worth the effort.
Calcite Springs Overlook surveys the north end of the Grand Canyon of Yellowstone, where the Yellowstone River leaves steep canyon walls for rolling prairie grasses. A butte just north of the overlook is draped by hydrothermally stained rhyolite that is bleach white and quite dramatic. Along the river at the bottom of these cliffs you’ll spot Calcite Springs, where steam rises from hydrothermal vents just feet from water’s edge. You might even catch a whiff of sulfur.
A display at the overlook offers this description Calcite Springs:
In cool weather, wisps of steam rise from Calcite Springs—the pale slope near river level. There the Yellowstone River flows above a volcanic fracture zone that allows geothermal discharge to reach the surface. Chemicals from Calcite Springs’ hot water vents are slowly turning the cliff to whitish, yellowish pulp.
There is another interesting feature running along the opposite wall of the canyon, a line of uniform volcanic pillars. The basalt columns testify to a more active volcanic period in Yellowstone’s past, when a 25-foot layer of lava flowed across the land.
A sign at the overlook offers this description of the flood of fire:
River canyons expose the landscape’s hidden excesses, it’s violent past. The orderly columns across the canyon are volcanic. From vents in the Yellowstone Plateau lava welled up and flowed—a vast flood of fire 25 feet (7.6m) deep. As the lava cooled and contracted about 1.3 million years ago, it formed contraction cracks, producing hexagonal columns of basalt.
Calcite Springs Overlook sits atop the narrowest section of the Grand Canyon of Yellowstone. Notches along the canyon wall are a popular nesting site for osprey. See if you can spot one of these large birds before returning to the trailhead. No permit is required to hike to Calcite Springs Overlook, but there is an entrance fee for Yellowstone National Park.

This 1-mile hike starts with a head-on view of a 132-foot waterfall. Unfortunately, the final leg of the trail to the base of Tower Fall is closed due to damage from rock and mud slides.
|Inspiration Point on the Grand Canyon of the Yellowstone|
This jutting point is one of the premier vistas along the Grand Canyon of the Yellowstone River, reachable at the bottom of a flight of stairs from a parking area at the east end of North Rim Trail.
