SNAP*Shot: Mammoth’s Palette Spring Season After Season

Mammoth Terraces, including beautiful Palette Spring, is not the only reason to visit this area. Coming through Yellowstone’s North Entrance, we drive up almost 1,000 feet along five miles to Mammoth Hot Springs. This is the home of historic Fort Yellowstone, still the park’s administrative headquarters. The significant conservation policies developed here lead to establishing the National Park Service in 1916. From 1886 to 1918 the US Army administered the park, turning those duties over to the fledgling Park Service in 1918. Enjoy Yellowstone’s fascinating history by taking the virtual tour. Delight in the stories that gave us the world’s first National Park.

Today, though, we are driving by the Visitor’s Center, hotel, dining areas, gas station, and the only heated restroom along the Norther Tier road–you have no idea how welcomed that is in winter! Our destination is the massive rock mound call Mammoth Terraces. Palette Spring is the colorful introduction to Yellowstone’s unique hydrothermal area called Mammoth.

Mammoth Upper Terraces–What a Difference a Day Makes

A winter morning on Mammoth Hot Springs’ Upper Terraces. Wow, what a difference a day hour makes! From blue skies to whiteout snow conditions in a matter of hours, but I always love the peace and beauty when walking the Upper Terraces. Let’s explore these amazing travertine terraces.

Snowshoeing Upper Terrace of Mammoth Hot Springs

The sun’s out! What a change from the gray landscape and snowy conditions we’ve seen day after day in Yellowstone. Let’s head to the Upper Terrace at Mammoth Hot Springs for a winter hike around the loop called Upper Terrace Drive. During the summer season (April-early November), this road is cars only. When snow falls, it becomes the domain of folks on skis and snowshoes.

The Mammoth upper and lower terraces form a massive hill of travertine. Travertine is the result of thermal (HOT mineral-laden) water rising through limestone. The water carries large amounts of dissolved limestone (calcium carbonate) as it races to the surface. Upon reaching the surface, carbon dioxide is released depositing the calcium carbonate which forms travertine, the chalky white mineral that forms the rock of the travertine terraces. Travertine formations grow rapidly due to the “soft” nature of limestone. They also change quickly as we will see along the trail. One fascinating fact that continues to amaze me is that all the extremely hot water creating this entire travertine area comes through a fault line in Norris Geyser Basin about 20 miles south. That is some hot-water pipeline. So my friend, strap on those snowshoes and let’s go!
