Mid-Day at Grand Prismatic Spring
The microbial mat is what brings out the most color in this, the largest hot spring in the United States, and the third largest in the world. During the summer the mats are redder, in the winter they can be dark green. The steam and water in the center are blue because of its sterility caused by the extreme temperatures.
This is a 7-image panorama taken mid-day in June of this year.
