Echinus Geyser Details

The largest acid-water geyser in the world, this truly strange geyser erupts between 40 and 60 feet in the air, releasing water nearly as acidic as vinegar for 5 minutes. The name comes from the spiny appearance of the geyser's cone and its likeness to a sea urchin. The geyser is currently a little unpredictable, and periods between eruptions vary drastically.
