One of the many thermal areas at Mammoth Hot Springs, Yellowstone National Park. A view taken from near the Canary Spring area, photographed on 12 September 2012. I loved the setting of this one, as it first showed up as a short, thin, orange-brown line in the far distance of the Main Terrace. The closer we got, the line turned into a spectacular display of delicate deposits and hot steam. I visited Mammoth Hot Springs and the rest of Yellowstone National Park 32 years ago, when my kids were very young. Loved Mammoth Hot Springs, so was thrilled to get the chance to see this fascinating area again. "Mammoth Hot Springs is a large complex of hot springs on a hill of travertine in Yellowstone National Park ... It was created over thousands of years as hot water from the spring cooled and deposited calcium carbonate (over two tons flow into Mammoth each day in a solution). Although these springs lie outside the caldera boundary, their energy has been attributed to the same magmatic system that fuels other Yellowstone geothermal areas... A caldera is a cauldron-like volcanic feature usually formed by the collapse of land following a volcanic eruption. They are sometimes confused with volcanic craters." en.wikipedia.org/wiki/Mammoth_Hot_Springs For a diagram of the Hot Springs layout: en.wikipedia.org/wiki/File:MammothHotSprings.JPG Map of Yellowstone National Park: hfc.nps.gov/carto/PDF/YELLmap2.pdf Why Nature's beauty gets destroyed and why people get killed: youtu.be/oVKqXsIs2mw

This was one of my favourite spots at Mammoth Hot Springs, Yellowstone National Park, Wyoming, US. Walking along near the Main Terrace, I could see just a distant spot of deep orange, having no idea of the magical scene we would see further down the boardwalk.
