THEMIS: Variations on a sandy theme in Kaiser Crater
THEMIS Image of the Day, January 26, 2018. This VIS image of Kaiser Crater shows a region of the dunes with varied appearances. The different dune forms developed due to different amounts of available sand, different wind directions, and the … Continue reading

THEMIS: Dunes on a topographic rise in Kaiser Crater
THEMIS Image of the Day, January 25, 2018. This VIS image of Kaiser Crater shows the central part of the crater floor. At the bottom of the image there is a topographic rise. The change in topography has altered the … Continue reading

THEMIS: Caterpillar dunes in Kaiser Crater
THEMIS Image of the Day, January 24, 2018. This VIS image of Kaiser Crater shows individual dunes and where the dunes have coalesced into longer dune forms. The addition of sand makes the dunes larger and the intra-dune areas go … Continue reading

HiRISE: Bedrock outcrops in Kaiser Crater
This enhanced-color image shows a patch of well-exposed bedrock on the floor of Kaiser Crater. The wind has stripped off the overlying soil, and created grooves and scallops in the bedrock. The narrow linear ridges are fractures that have been … Continue reading

THEMIS: Warm dunes glowing in Kaiser Crater
THEMIS Image of the Day, March 9, 2017. This is an infrared image of Kaiser Crater and the dune field on the crater floor. Brighter tones in the image are warmer surfaces. The basaltic dunes are dark in the visible, … Continue reading

HiRISE: Scars of erosion
This large crescent dune in Kaiser Crater shows the scars of many types of seasonal erosional activities. Along its downwind slope are large gullies which are active during winter, when frost drives dune material downslope, carving out channels and creating … Continue reading

HiRISE: Frosty alcoves on Kaiser Crater dunes
Kaiser Crater hosts a large field of sand dunes. Every winter the dunes are covered with a layer of seasonal carbon dioxide ice (dry ice). In early spring the ice begins to sublimate (going directly from solid ice to gas). … Continue reading

HiRISE: Glowing gullies in Kaiser Crater dunes
The giant sand dunes in Kaiser Crater experience gully erosion of the steep slip faces every year in late winter as the sun warms these slopes and seasonal carbon dioxide frost sublimates (meaning it changes from a solid to gas). … Continue reading
