Description

This beautiful scene is part of the Mammoth Hot Springs Terrace in North Yellowstone National Park, and the Albright Visitor Center. I was there in the middle of winter, and firmly believe that it is very essential that at least one visit to Yellowstone is made during this time of year to fully understand how much heat is just below your feet. I went once in the Spring and did not experience seeing just how many steam vents there really are. The Caldera that is just under ground encompassing this entire park is one of the largest Calderas in the world. I am in awe of the power that builds up and then bursts out in the Geysers and hot pools of this beautiful park.

Hot Springs are similar to geysers, but they have no constrictions in their plumbing. Superheated water cools and circulates as it reaches the surface and is replaced by hotter water from below. This circulation, called convection, prevents water from reaching the temperature needed to set off the chain reaction leading to an eruption. The many beautiful colors you see in hot springs are caused by light refraction, suspended mineral particles, and heat-loving microorganisms.

Thermal Features: As you explore Yellowstone's geothermal areas, you will notice trails consisting of boardwalks or asphalt. This is not to minimize ground disturbance. Since many geothermal areas have a very thin crusts, such walkways also allow safe passage. Even a child can break through this delicate crust, resulting in serious burns from steam or scalding water.
