List of craters on Mars: A-G

This is a list of craters on Mars. There are hundreds of thousands of impact craters on Mars, but only some of them have names. This list here only contains named Martian craters starting with the letter A – G (see also lists for H – N and O – Z).

Large Martian craters (greater than 60 km in diameter) are named after famous scientists and science fiction authors; smaller ones (less than 60 km in diameter) get their names from towns on Earth. Craters cannot be named for living people, and small crater names are not intended to be commemorative - that is, a small crater isn't actually named after a specific town on Earth, but rather its name comes at random from a pool of terrestrial place names, with some exceptions made for craters near landing sites. Latitude and longitude are given as planetographic coordinates with west longitude.

Gunnison River

The Gunnison River is a tributary of the Colorado River, 164 miles (264 km) long, in the Southwest state of Colorado. It is the fifth largest tributary of the Colorado River, with a mean flow of 4320 ft³/s (122 m³/s).

Description

The Gunnison River is formed by the confluence of Taylor and East rivers at Almont in eastern Gunnison County. Just past the town of Gunnison, the river begins to swell into the expanse of Blue Mesa Reservoir, a 36-mile (58 km) long reservoir formed by Blue Mesa Dam, where it receives the Lake Fork of the Gunnison. Just downstream it is dammed again to form Morrow Point Reservoir, then just downstream of that dam for the final time to form Crystal Reservoir. The reservoirs produce hydroelectric power and supply water for the surrounding areas for both municipal and irrigation use. The reservoirs are the upper part of the Black Canyon of the Gunnison, one of the longest, narrowest, and deepest gorges in the world. Below Crystal Dam it begins to roar through massive cataracts and flows through the deepest part of the gorge. At the outlet of the canyon it receives the North Fork River, then downstream near Delta, Colorado is joined by the Uncompahgre River. It then winds through desert canyonlands, where it receives Kannah Creek before it empties out of the Dominguez Canyon into the Colorado in Grand Junction, some years rivaling the Colorado River for equal if not slightly less volume.
