The Great UnconformityPhotographer and Summary Author: Stan Celestian
One of the most geologically interesting views displayed on the walls of the Grand Canyon in Arizona, is the Great Unconformity. This view was captured from Desert View, in the eastern portion of Grand Canyon National Park. Its greatness lies in the vast amount of missing time it represents as well as its large lateral extent. Specifically, the Great Unconformity is an angular unconformity. The younger (550 million years ago) Cambrian Period Tapeats Sandstone rests unconformably on the much older& sedimentary Grand Canyon Supergroup (about 740 to 1,200 million years ago). At about 730 million years ago, these rocks were tilted 15 degrees to the northeast and faulted during the Grand Canyon Orogeny. This tilting created a mountain range in the area that was subsequently eroded to a nearly flat horizontal surface. The deposition of the coarse sands and gravels on this erosional surface was later to become the Tapeats Sandstone that defines the upper limit of the angular unconformity. Thus, this unconformity represents a gap in the geologic history& of the Canyon that varies along its lateral extent and spans about 200 to 1200 million years — enough time for an entire mountain range to be eroded flat!

At the start of the game, it is possible to make Duke crouch down in his own jacuzzi and hold his head underwater until he drowns.

This is the good ending because it means that you don’t have to play the rest of Duke Nukem Forever.

A Tantalising Veil

This image shows a small portion of a nebula called the Cygnus Loop. Covering a region on the sky six times the diameter of the full Moon, the Cygnus Loop is actually the expanding blastwave from a stellar cataclysm - a supernova explosion - which occurred about 15,000 years ago.

This delicate Hubble Space Telescope image shows a tiny portion of the Cygnus loop, a supernova remnant in the constellation of Cygnus, the Swan. Measurements on this super-detailed image of a cosmic veil shows that the original supernova explosion took place only 5, 000 years ago.

Green laser light enters the water-filled, quartz chamber from the left and hits the bubble of xenon gas (center). Sound waves compress the bubble 30,000 times per second, repeatedly turning it into a 10,000-kelvin, 1-micrometer-wide ball of plasma. The black object in the foreground collects the scattered laser light.
