Examples of the ‘Kieffer zoo’ features proposed to be formed by seasonal carbon dioxide sublimation dynamics on Mars: (a) ‘thin’ spiders within the south polar layered deposits; (b) dark spots on top of a layer of translucent carbon dioxide slab ice covering a cluster of ‘fat’ spiders at Martian ‘Inca City;’ (c) ‘fried eggs’ showing rings of dark dust surrounded by bright halos; (d) patterned ground within the high south polar latitudes with dark oriented fans indicative of wind direction and some bright, white fans; (e) bright halos surrounding Swiss cheese depressions; (f) ‘lace terrain,’ a type of patterned ground suggested to be polygonally patterned ground later scoured and eroded by surface-flowing carbon dioxide gas from the Kieffer model.
