Yellowstone National Park in Park County, Wyoming — The American West (Mountains)
Morning Glory Pool is losing its brilliant color. Through ignorance and vandalism, people have tossed objects into the hot spring, clogging its vent and lowering the temperature. Brown, orange, and yellow algae-like bacteria thrive in the cooler water, gradually turning the vivid aqua-blue to a murkier greenish-brown.
All thermal features are at risk. Hot springs and geysers have fragile, complex plumbing that takes centuries to develop. Morning Glory’s future is uncertain; you can help by immediately reporting any vandalism.
