When you walk along the Trail of the Shadows in Longmire you may notice a large section of bare, yellowish-tan ground on the west side of the Longmire meadow. This area is covered in travertine, a layer of calcium carbonate deposits created by volcanic mineral springs. The mineral springs are still active, constantly building up more travertine deposits. A short spur trail leads to one of these active springs.
The edge of the spring is wrapped in travertine and mineral deposits are building up along the path of the overflowing spring water. The spring also has green algae growing in it and iron minerals give the water a reddish color. Please protect this feature by staying on the trail and not disturbing the spring.
What other signs of volcanic activity have you seen in the park?

Freshwater crabs dating back to the Pleistocene period, approximately 600 thousand to 1.1 million years ago, were formed in Denizli, Turkey. What makes these fossils unique is that no other fossilized freshwater crabs in the world have been found preserved within their own habitat (travertine). These exceptional fossils were discovered in a marble/travertine mine
