Archaeologists have unearthed hundreds of Clovis stone tools at the 13,000-year-old campsite of Belson in southwest Michigan; Clovis people traveled to this site annually, probably in the summer, for at least three but likely up to five consecutive years; the stone artifacts also show evidence that the settlers’ diets included a wide variety of animals, ranging from rabbits to musk ox. Clovis people likely returned to the Belson campsite in southwest...

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.
