Grand Prismatic Spring

This perspective of Grand Prismatic Spring was taken from a hilltop just off the Fairy Falls Trail, and provides a considerably different vista in contrast to boardwalk views of the spring from Yellowstone’s Midway Geyser Basin.

One of the world’s largest intact remaining hot springs, Grand Prismatic is approximately 200 feet across and over 100 feet deep, yet all of Yellowstone’s thermal features remain vulnerable to human disruptions and impacts such as littering and vandalism .Colors closer to hot spring edges are generally microbe-colored mineral deposits, while colors in the spring itself usually indicate the presence of heat-thriving organisms known as thermophiles.
