Gullies in Acidalia Planitia

This crater is located in Acidalia Planitia. It is situated in a sparsely cratered area of elongated mounds and hosts a variety of gully forms on its eastern, northern, and western interior slopes. This observation is centered on the crater's western slope and captures gullies with prominent alcoves, boulders, and outcrops. The incised gully channels terminate in a variety of alluvial fans. Some have edges or margins that are finger-like with light-toned deposits while other fans are more lobe-shaped. Many have fractures mid-slope that appear to have cut across the gullies and may suggest glacial processes were once active. Fractures such as these are similar to what are known as "glacial crevasses" on Earth. Linear stippled regions cover the floor of the crater that may represent areas of subsurface ice sublimation. https://photojournal.jpl.nasa.gov/catalog/PIA23145
