The Midway Geyser Basin is home to stunning hot springs, including the Grand Prismatic Spring and the massive Excelsior Geyser.
The geyser is located just above the Lower Geyser Basin, and has a collection of some huge and stunning hot springs. The main attraction in this area is obviously the captivating Grand Prismatic Spring, with it's rainbow coloured surface and the water a shade of the most amazing blue you've seen. The Excelsior Geyser, also located here, used to be the largest geyser in the world. It is today dormant, and has one of the biggest hot springs of the area. It is believed that it's eruptions were so violent, they over time cracked the siliceous sinter lining, causing gas leak and hence leading to loss of thermal energy. Nevertheless, the active hot spring today is almost always covered by a thick layer of steam. The richly coloured Turquoise and Indigo hot spring are also noteworthy. Both of them are named on their colour, and aptly so.
