The rule here

This is a thermal feature to see, not a place to get in the water. The San Juan National Forest puts it this way:

“Swimming and bathing are NOT recommended.”

Worth knowing: The Forest warns that carbon dioxide and hydrogen sulfide gas displace oxygen near the water’s surface here and directs viewing from above the geyser.
