West Thumb Geyser Basin

West Thumb Geyser Basin is the largest geyser basin on the shores of Yellowstone Lake. A well-maintained boardwalk provides easy access to all the geothermal features and is a great place to walk around and explore. West Thumb has the least amount of geyser activity compared to the other basins. But West Thumb, for its size, has it all-hot springs, pools, mud pots, fumaroles and lake shore geysers which make it so interesting. Since the mid 1970s, West Thumb has decreased in thermal activity. Some temperatures have cooled in the basin allowing large colonies of algae and cyanobacteria to grow. As a result, large newly-formed microbial mats flourish on the run-off channels and along the edges of pools. Here’s an example.
