 Because of its close proximity to the Broken Mammoth site it can be inferred that the climate at Swan Point was similar with lowland tundra and low vegetation.Charcoal remains indicate wood from Populus and Willow which are associated with the oldest artifacts found at the site.The stratigraphy at Swan Point is slightly different from the other sites in the Tanana River Valley; it is thinner because it is farther from the Tanana River.
