The landscape then experienced an extended warm and dry spell known as the Hypsithermal Interval, or Xerothermic Period.
His solution is to argue that it was mapped during a period of warmer climate (the Hypsithermal Interval or the Medieval Warm Period) when the Ross Ice Shelf had disappeared.
As reviewed in Tuma (2006), disjunct populations are believed to be remnants of populations that dispersed northeastward during the hypsithermal period (ca.
Her topics include thinking about archaic hunter-gatherers, the location of shell-bearing sites, the over exploitation of mollusks, the demise of the Hypsithermal, whether there were villages, archaic rituals at shell-bearing sites, and the theoretical landscape from archaic villages to ritual camps.
Characteristic sand savanna and sand prairie vegetation became established during the Hypsithermal period about 8,000 years ago (King 1981).
The effects of the Hypsithermal on prehistoric foraging efficiency in Missouri.
During the preceding Medieval Warm Period, which peaked at about 1000 AD, Alpine ice cover in the northern hemisphere was substantially less than at present, and over much of the Canadian Cordillera there may have been no glaciers at all during the Holocene Maximum or Hypsithermal (about 86.5 ka), a period during which climates were considerably warmer than at present (an effect of orbital forcing).
Several lacustrine cores from Silver and Stony Lakes, Oceana County, MI were obtained by vibracoring for the purpose of determining if there was climate variability recorded during the Little Ice Age, the hypsithermal episode, the 8.2ka event and the Younger Dryas cold period.
Some authors suggest dry mid-Holocene conditions (Prieto 1996), while others interpret the record as evidencing a moister mid-Holocene climate (from 8500 RCYBP to 3500 RCYBP), based on the concept of "Climatic Optimum" or Hypsithermal (Iriondo 1999; Krohling 1999; Krohling and Iriondo 1999).
