List of Slides for Hot Springs NP

These slides are actually from Hot Springs State Park in Thermopolis, Wyoming. They show springs and deposits similar to those at Hot Springs NP in Arkansas.

• Hot water from the springs deposits tufa at the surface and around the edges of the water. Tufa is a spongy-looking form of calcium carbonate.
• Tufa builds up terraces around the springs. Different levels form as the volume of water flowing out of the spring changes.
