The water returns to the ground at lower latitudes as deposits of frost or snow mixed generously with dust. The atmosphere of Mars contains a great deal of fine dust particles. [51] Water vapor condenses on the particles, then they fall down to the ground due to the additional weight of the water coating.
Image of gullies with main parts labeled. The main parts of a Martian gully are alcove, channel, and apron. Since there are no craters on this gully, it is thought to be rather young. Picture was taken by HiRISE under HiWish program. Location is Phaethontis quadrangle.
Korolev is an ice-filled impact crater in the Mare Boreum quadrangle of Mars, located at 73° north latitude and 165° east longitude.It is 81.4 kilometres (50.6 mi) in diameter [1] and contains about 2,200 cubic kilometres (530 cu mi) of water ice, comparable in volume to Great Bear Lake in northern Canada.

The Perseverance spacecraft landed on Mars in February 2021 and has been doing reconnaissance missions and looking for signs of life.
Liquid water in the ejected material forms a muddy slurry that flows along the surface, producing the characteristic lobe shapes. [54] [55] The crater Yuty is a good example of a rampart crater, which is so called because of the rampart-like edge to its ejecta blanket. [56]
Garni is an impact crater on Mars, [1] in which, according to NASA, there is evidence of liquid water. [2] [3] In the press release of its finding on 28 September 2015, NASA considered it "the latest of many breakthroughs" in their Mars exploration. [3] NASA and the US Geological Survey named the crater after the Armenian village of Garni.
English: How crater-depth is measured, using the side-view of a typical crater. Depth "A" measures from the surface to the bottom of the crater. Depth "B" measures from the mean height of the rim to the bottom of the crater.
Crater Lake actually started as a mountain, Mount Mazama. A volcanic eruption roughly 7,700 years ago caused the mountain to collapse inward over time, forming a volcanic crater, the park says.
