La Garita, Colorado
These magnificent ash formations are the legacy of perhaps the largest explosive eruption in the earth’s history. Some 28 million years ago the Colorado eruption disgorged more that 1,200 cubic miles of lava – enough to fill the basin of Lake Michigan. The resultant, oblong-shaped caldera, located in Colorado’s San Juan Mountains, measures around 22 by 47 miles.
