La Brea Tar Pits (by Hollywood History Tours)

The La Brea Tar Pits are LA’s direct link to prehistory—natural asphalt seeps that trapped unsuspecting prehistoric animals, creating a huge treasure trove of fossils dating back to the last ice age.

Elakala Falls
The photo above shows beautiful Elakala Falls at Blackwater State Park near Davis, West Virginia. These falls form as Shay’s Run plunges down a mountain ravine into the Blackwater River canyon. This view is of the first, and most widely visited, of a series of four cascades that make up Elakala Falls.
It drops 35 ft (11 m) over a ledge composed of Carboniferous sandstone. Downstream, the resulting current and orientation of rock outcrops creates a whirlpool which is quite pronounced here because of the photo’s long exposure time. Photo taken in June 2009.

Waterfall, Moonbow, and Aurora from Iceland
The longer you look at this image, the more you see. Perhaps your eye is first drawn to the picturesque waterfall called Skogarfoss visible on the image right. Just as prevalent, however, in this Icelandic visual extravaganza, is the colorful arc of light on the left. This chromatic bow is not a rainbow, since the water drops did not originate in rainfall nor are they reflecting light from the Sun.
Rather, the drops have drifted off from the waterfall and are now illuminated by the nearly full Moon. High above are the faint green streaks of aurora. The scene, captured one night last month, also shows a beautiful starscape far in the background, including the Big Dipper, part of the constellation of the Great Bear (Ursa Major).
