Wonderful to be in Yellowstone without the crowds. Unfortunately, only had time for a short hike so opted for Mystic Falls – that way I could take in the geological wonders at Biscuit Basin first with the added bonus of a waterfall and vista of the Upper Geyser Basin.
Silex Spring, the photo at the top of the page, was one of the most spectacular geothermal pools, but there were many contenders. It was mesmerizing to watch what seemed to be sporadic eruptions from pool to pool. After a while, you notice that the eruptions are actually sequential with the water draining from one pool and filling the next.
