Seasonal Flows in the Central Mountains of Hale Crater
Recurring slope lineae are active flows on warm Martian slopes that might be caused by seeping water. One of the most active sites known is in the central peaks of Hale Crater as seen by NASA's Mars Reconnaissance Orbiter.
There are some interesting erosional signs in this observation from NASA's Mars Reconnaissance Orbiter, which will make for a good comparison with other intracrater fans and fluvial sedimentary landforms.
This frame from a sequence of images shows a blast zone where the sky crane from NASA's Curiosity rover mission hit the ground after setting the rover down in August 2012. The images are from HiRISE on NASA's Mars Reconnaissance Orbiter.
This observation from NASA's Mars Reconnaissance Orbiter shows an interesting crater floor with what appear to be inverted channels, rounded lobe-like landforms, and light-toned layered deposits along the southern portion of the crater wall.
This image is of a portion of the Southern plains region within Hellas, the largest impact basin on Mars, with a diameter of about 2300 kilometers (1400 miles), as observed by NASA's Mars Reconnaissance Orbiter.
This image from NASA's Mars Reconnaissance Orbiter covers Raga Crater, the location of well-studied recurring slope lineae (RSL). RSL are dark flows that disappear and re-form every Mars year at certain locations.
Gullies and Layers in a Crater Near Mariner Crater
Gullies are commonly found in the southern mid-latitudes of Mars. In this image from NASA's Mars Reconnaissance Orbiter they start near top of a long ridge, and descend into an impact crater that lies at the bottom of the ridge.
This image from NASA's Mars Reconnaissance Orbiter shows dark dunes in the western Medusae Fossae. This image shows no large dunes, but many of the dark sand patches cover slopes up to discrete layers.
Bigbee is a 21 kilometer-diameter impact crater located on the northern rim of Holden crater in southern Margaritifer Terra, a region on Mars that is well known for its long record of water-rich activity as seen by NASA's Mars Reconnaissance Orbiter.
