A great blue heron and great egret in the parking lot by the Big Cypress Bend
boardwalk at Fakahatchee Strand State Preserve. The heron is enjoying a fish
dinner thanks to the hunting skills of the egret. While the egret had initially
held a fish in it's beak, the heron's squabbling caused the egret to drop it.

Looking towards NW across Lavic Lake, rupture passing from lower right, stepping out toward upper left; NW end of the surface rupture is in the distance on the far side of Lavic Lake.

Lake Baikal is the largest, oldest, and deepest freshwater lake in the world
Lake Baikal, the world’s oldest and deepest freshwater lake, curves for nearly 400 miles through south-eastern Siberia, north of the Mongolian border. At its deepest point it is over 5,000 feet (1,637 meters) deep.

Cracks on far side of wash; called 'en-echelon' breaks where they step sideways.

View downward onto site with maximum observed lateral displacement along the Lavic Lake fault. Here a vehicle track and dry creek bed are laterally offset by approx. 370-480 centimeters. The orientation of fractures here is nearly North-South.

Fracture cutting across the countryside (left to right) such that the fault scarp is lit up by the sun, appearing as a bold white line.

View towards south across Lavic Lake, with the surface rupture running from lower right to upper left. In the middle distance on the right is an ancient lava flow.

Ground view along surface rupture, showing the fracturing of the soil and how pieces have been pushed up within the fault zone.

Subparallel breaks coalesce on face of hill (in shadow) and form a single rupture heading off to the upper left.

Downward view onto gullies, gravel bar, and other laterally offset features. Here slip appears to be about 2 meters.

Southeast of maximum displacement site. Here we see 3-4 meters of right-lateral slip have offset a ridge and created a 'shutter' ridge blocking flow in the dry creek channel. The white vertical surface is the fault scarp.

View right along the main rupture zone, and also visible is a subsidiary fracture from lower-right corner coalescing with the main break in the middle distance.

View downward onto vehicle tracks crossing the fault at a high angle. One can see 2.5 to 3.5 meeter right-lateral displacement of the tracks.

The south area of the La Honda oil field, California, was discovered during the late 1950s and produced an estimated 595,000 barrels of oil from about 12 wells, including the well in this photo.
