Pyramid Lake, Nevada, is one of the last remaining strongholds for lacustrine Lahontan cutthroat trout; almost all other large lake populations have undergone population declines or extirpation as a result of habitat degradation, overharvest, and water diversions, all compounded by the stocking of nonnative species.

Four video cameras look westward over the coast and the coral reef at Tres Palmas in Rincón, on the west coast of Puerto Rico. Two cameras look out at the horizon and over the ocean for the mid-field view; one camera offers a zoomed-in, far-field view overlooking the reef and out to the island of Desecheo, a U.S.

Alteration associated with mud pots in Yellowstone National Park. Left image is an overview of Artist Paint Pots. Note the white kaolinite alteration in the lower right and the red/pink mud pots near the boardwalk. Right image is charcoal-gray mud from Mud Volcano consisting of kaolinite with fine-grained pyrite and other iron sulfide minerals.
