Seemed to have coincided with the growing population of Indian hunters.
"Native Americans" / Ohio - "[....] So far, they've found and catalogued more than nearly 7,000 artifacts that were buried within two feet of the ground's surface. Most are pieces of pottery, tools, arrowheads and other objects used by Native Americans that began inhabiting this part of southwestern Hamilton County [Ohio] in 11,000 B.C.

Plentiful Wild Game / Ohio - "North-central Ohio's flat, almost featureless landscape is covered with fields of corn, soybeans, wheat, and alfalfa as far as the eye can see. But at Sheriden Cave, more than 32 feet below the surface, we have found remains of plants and animals that tell of a very different landscape at the end of the Ice Age, some 12,000 to 13,000 years ago. Then, there were spruce and pine parklands, open patches of grassland interrupted by occasional cedars, and shallow streams and wetlands bounded by willows and poplars. Some of the animals inhabiting this landscape - white-tailed deer, raccoon, woodchuck, and fox - are found in Ohio today, while others - caribou, pine marten, and lemming - were far south of their modern ranges. Most spectacular were the now extinct species, including short-faced bear, giant beaver, stag moose, and herds of pig-like peccaries. In this game-rich environment, a small band of hunters made use of the cave." [Source? Link?]
Ancient Human Bones In 1959, the partial skeletal remains of an ancient woman estimated to be 10,000 years old were unearthed in Arlington Springs on Santa Rosa Island, one of the eight Channel Islands off the southern California coast. They were discovered by Phil C. Orr, curator of anthropology and natural history at the Santa Barbara Museum of Natural History. The remains of the so-called Arlington Springs woman were recently reanalyzed by the latest radiocarbon dating techniques and were found to be approximately 13,000 years old. The new date makes her remains older than any other known human skeleton found so far in North America."
In 1959-60, two femurs were excavated at a site called Arlington Springs on Santa Rosa Island. Responsible for the digs was Phil C. Orr, Curator of Anthropology at the Museum of Natural History in Santa Barbara. He published his findings in Science 135, 3499 (1962): 219 and American Antiquity 27, 3 (1962): 417-419, followed up by full account in Prehistory of Santa Rosa Island (Santa Barbara, 1968). Jon Erlandson reviews the evidence Orr collected at Arlington Springs in Early Hunter-Gatherers of the California Coast (New York: Plenum, 1994), pp. 184-186. [....] The main discovery is that Arlington Springs Man was in fact a woman and significantly earlier than previously thought. Radiocarbon dating has moved Orr's estimate of 10,000 years ago back to 13,000 B.P." 10,970 B.C. - Equinox at Leo - "According to one report, the Age of Leo spanned from 10,970 B.C. to 8,810 B.C.
