Lau Crater is an impact crater in the Mare Australe quadrangle of Mars, located at 74.4°S latitude and 107.8°W longitude. It is 104.9 km in diameter. It was named after Danish astronomer Hans E. Lau, and the name was approved in 1973 by the International Astronomical Union (IAU) Working Group for Planetary System Nomenclature (WGPSN).
The curved ridges observed on the crater floor are believed to be eskers, which form when streams run under a glacier.Namowitz, S., D. Stone. 1975. Earth Science The World We Live In.

Martian dust devils (dust devils on Mars) were first photographed by the Viking orbiters in the 1970s. In 1997, the Mars Pathfinder lander detected a dust devil passing over it. In the first image below, photographed by the Mars Global Surveyor, ...
