Bacterial Mat at Grand Prismatic Spring
Midway Geyser Basin is actually part of the Lower Geyser Basin in Yellowstone National Park. Since it is situated betweeen the Lower and Upper Geyser basins it became known as Midway. During his visit to Yellowstone in 1889, Rudyard Kipling referred to this area as "Hell's Half Acre".
Midway contains one of the worlds largest hot springs, Grand Prismatic Spring, at approximately 370 ft. in diameter. Other notable springs are Turqoise and Indigo Springs. Also here is Excelsior Geyser, that dischargres more than 4000 gallons of boiling water every minute.
This is an image from my trip out west late last summer. The bacterial mat pictured here is actually the one created by Grand Prismatic Spring, which is directly behind me in this shot.
I hope everyone had a great weekend.
