Eureka Dunes. The Eureka Valley Sand Dunes are California's tallest sand dunes, and one of the tallest in the United States. Rising 680' above the floor of the Eureka Valley, the Eureka sand dunes are home to several endangered species, as well as "singing sand" that makes strange sounds when it shifts. Located in the remote northern portion of Death Valley National Park, the Eureka Dunes see very few visitors.

A sliding rock of the Racetrack Playa. The sliding rocks, or sailing stones, move across the mud flats of the Racetrack Playa, leaving trails behind in the mud. The explanation for their movement is not known with certainty, but many believe wind pushes the rocks over wet and perhaps icy mud in winter.

A great white shark bearing a white plastic researcher's identification ID tag near its dorsal fin swims through the clear waters of Isla Guadalupe, far offshore of the Pacific Coast of Baja California. Guadalupe Island is host to a concentration of large great white sharks, which visit the island to feed on pinnipeds and tuna.
Species: Great white shark, Carcharodon carcharias

A great white shark is countershaded, with a dark gray dorsal color and light gray to white underside, making it more difficult for the shark's prey to see it as approaches from above or below in the water column. The particular undulations of the countershading line along its side, where gray meets white, is unique to each shark and helps researchers to identify individual sharks in capture-recapture studies. Guadalupe Island is host to a relatively large population of great white sharks who, through a history of video and photographs showing their countershading lines, are the subject of an ongoing study of shark behaviour, migration and population size.
Species: Great white shark, Carcharodon carcharias
Location: Guadalupe Island (Isla Guadalupe), Baja California, Mexico
