Remains of a southwestern pond turtle in Elizabeth Lake, California

Salt-encrusted remains of a southwestern pond turtle (Actinemys pallida) as found in the dry lake bed of Elizabeth Lake, Los Angeles County, California. Note the heavy coating of evaporites on the carcass. Most living turtles collected in 2014 had similar but varying degrees of coatings on the head, limbs and shell.

Almost all of the turtles living in a southern

Glen Canyon Dam jet tubes releasing water for a high flow experiment

Glen Canyon Dam jet tubes releasing water into the Colorado River for a high flow experiment. The increase in flow of the Colorado River downstream of the dam mobilizes sand at the bottom of the river and that sand rebuilds sandbars in Grand Canyon.
