Back from the shore the land is but slightly elevated, and is marshy and interspersed with many small lakes and ponds, sometimes connected by inconsiderable streams. This marsh passes gradually into a somewhat higher and drier rolling plain, stretching back inland from the cliffs and growing gradually higher to the south. Dr. Simpson, on the authority of the Point Barrow natives, describes the country as “uniformly low, and full of small lakes or pools of fresh water to a distance of about 50 miles from the north shore, where the surface becomes undulating and hilly, and, farther south, mountainous.”[N6] This description has been substantially verified by Lieut. Ray’s explorations. South of the usual deer-hunting ground of the natives he found the land decidedly broken and hilly, and rising gradually to a considerable range of mountains, running approximately east and west, which could be seen from the farthest point he reached.[N7] [Footnote N6: Arctic papers, p. 233.] [Footnote N7: Report U.S. International Polar Expedition to Point Barrow, p. 28.] The natives also speak of high rocky land “a long way off to the east,” which some of them have visited for the purpose of hunting the mountain sheep. The low rolling plain in the immediate vicinity of Point Barrow, which is all of the country that could be visited by our party when the land was clear of snow, presents the general appearance of a country overspread with glacial drift. The landscape is strikingly like the rolling drift hills of Cape Cod, and this resemblance is increased by the absence of trees and the occurrence of ponds in all the depressions. There are no rocks in situ visible in this region, and large bowlders are absent, while pebbles larger than the fist are rare. The surface of the ground is covered with a thin soil, supporting a rather sparse vegetation of grass, flowering plants, creeping willows, and mosses, which is thicker on the higher hillsides and forms a layer of turf about a foot thick. Large tracts of comparatively level ground are almost bare of grass, and consist of irregular hummocks of black, muddy soil, scantily covered with light-colored lichens and full of small pools. The lowlands, especially those back of the beach lagoons, are marshes, thickly covered with grass and sphagnum. The whole surface of the land is exceedingly wet in summer, except the higher knolls and hillsides, and for about 100 yards back from the edge of the cliffs. The thawing, however, extends down only about a foot or eighteen inches. Beyond this depth the ground is perpetually frozen for an unknown distance. There are no streams of any importance in the immediate neighborhood of Point Barrow. On the other hand, three of the rivers emptying into the Arctic Ocean between Point Barrow and the Colville, which Dr. Simpson speaks of as “small and hardly known except to persons who have visited them,”[N8] have been found to be considerable streams.
