The headland is an important archaeological site, yielding burials and artifacts associated with the Thule culture, including uluit and bola. See companion file Barrow_Tundra_Veg_Plots_Photographs.pdf. Positive latitudes are north of the equator, negative latitudes are south of the equator. Archaeological evidence indicates that Point Barrow was occupied by the ancestors of the Iñupiat for almost 1,000 years prior to the arrival of the first Europeans.

The method consists of recording the composition of vegetation in plots each of which is a linear, contiguous arrangement of ten 1 x 1m quadrats placed in a visually homogeneous patch. The water around it is normally ice-free for two or three months a year, but this was not the experience of the early explorers. In sections of tundra that occur in proximity to the oceans or large bodies of water. The Alaska North Slope is the region of the U.S. state of Alaska located on the northern slope of the Brooks Range along the coast of two marginal seas of the Arctic Ocean, the Chukchi Sea being on the western side of Point Barrow, and the Beaufort Sea on the eastern. These areas of open water, called leads, are favorite places for sea mammals to congregate, as they provide areas to surface and breathe and to haul out and feed. past six decades near Barrow Alaska.

Even during the winter, some ice would be grounded in shallow waters near the shore, but farther out, long breaks would develop in the floating ice as winds and ocean currents push and pull at it.
