"The fertile agricultural belt of North America has been frozen out of existence by the advancing ice. The rolling fields have been replaced by a freezing, featureless desert."
The North American Desert is a large desert and brushland region running down the midwestern region of North America in 5 million AD. Bordered to the north by a vast polar ice sheet, the desert is barren, arid, and very cold.
This cold desert has extremely cold winters. There are high, flat areas, called plateaus and mountainous areas. In addition, the deserts get very little rain or snow. Plants and animals that live here are specially adapted to these extremely dry conditions.
Beneath the sand of the Desert is an extended system of underground reservoirs formed out of limestone caves and water-filled fissures, which stretch out for thousands of kilometres.
The shelly debris of vanished marine life below the mud was easily eroded and dissolved by acids in the groundwater, creating small holes in the rock, which eventually grew into large caves. These caves were filled with water by constant rainstorms which drenched the seaward mountain slopes and soaked into the strata, eventually seeping into the porous limestone in the centre of the continent.[2]
The water from these reservoirs seeps up to the surface, creating small lakes, pools, and oases which provide the only water on the desert's surface.[3] Since they're supplied by the underground reservoirs, these pools never evaporate, despite the heat.
