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.
It has been a gray winter in Yellowstone. Overcast, snow, and WIND. During a few days stay in mid-February, however, there was a sweet moment early in the week. We pulled into a protected pullout near the Yellowstone River. This poor old grandma Bighorn sheep headed toward us and we retreated to make room, but there is not much room to retreat in this pullout. OK, OK, she was about 10 feet away–don’t tell. We are supposed to stay 25 yards from such wildlife, even when they come to us. Broken horn on far side, looks like arthritis in her front shoulders, eyes somewhat sunken, moving very slow–all alone and females travel in groups. For a few minutes she just hung with us, checking us out every once in a while but not anxious, fearful, or in a rush to leave. Perhaps for a moment we offered safety and a sense of peace. With our presence, wolves are very unlikely. We may be just about the last people to see her alive.
A tribute to your life, sweet girl.
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!
How exciting to be traveling into Yellowstone via snowcoach on this winter day, although a very gray winter day. Our trip has been planned for about a month so come what may, we are going. It is totally overcast, snowing occasionally, but not too cold–in the mid 20’s. Since we are all photographers, we hope the weather will improve, but ya pay for ya ride and take ya chances!
We left West Yellowstone traveling through the West Entrance. We will be driving to Madison Junction then to Old Faithful, with stops all along the way at the various thermal basins. As we drive along the Madison River, we are hoping to see a bobcat or the pair that have been hunting in the river over the last few weeks. Keep your fingers crossed. We’ll also hope for some sun as the day progresses, then again, there is never a bad day in Yellowstone!
