Midway Geyser Basin is a collection of springs and geysers along the Firehole River in Yellowstone National Park. The geyser basin is located in a low flat area that was left uncovered by surrounding lava flows. Midway Geyser Basin is an extension of the Lower Geyser Basin but due to the isolated location between the main features of the Lower and Upper Geyser Basins, it became known as Midway. In 1889 Rudyard Kipling visited Yellowstone and referred to Midway Basin as “Hell’s Half Acre”. This steaming geyser field is home to two of the worlds largest hot springs, the Grand Prismatic Spring and Excelsior Geyser. Large colonies of algae, cyanobacteria, thermophiler and other heat loving micro-organisms tint the thermal areas with brilliant colors |
