Not illustrated. 1907 Excerpt: ... into Anvil Creck within a short distance of Snake River. pocket.) The floor of the valley is deeply gravel filled, and in some places the gravels rise in bluffs from 20 to 50 feet above the present flood plain. The flood plain ranges from 100 feet to a mile in width and at its lower end merges with the coastal plain. For 14 miles the gradient is about 10 feet to the mile and for 10 miles above this it is about 50 feet to the mile; the upper 5 or 6 miles are torrential. Colors of gold have been found on the river bars for 20 miles from the mouth and are reported from prospect holes in the flood plains 10 or 12 miles from the coast, but as yet no attempts to extract the gold have been successful. PIacers have been worked on many of the tributaries from both sides. The placers of the tributaries from the east, which are first described, are of leas importance than those on the west, which include some of the richest diggings on the peninsula. Osborn Creek.--Osborn Creek, the first large tributary of Nome River from the east, occupies a rather broad valley, the upper part of which is cut in siliceous chlorite schists and limestones of the Nome group. The mountain north of the mouth of Osborn Creek is composed almost entirely of greenstone, great blocks of which have rolled into the creek, forming bowlders of all sizes up to 10 feet in diameter. The gravels also contain many pebbles and bowlders of granite, which have probably been transported southward from the Kigluaik Mountains. (See pp. 94-99.) Similar granite bowlders are found up to an elevation of 800 feet on the mountain west of the creek. Although gold was discovered on this creek as early as 1900, very little development work has been done. It is reported that during the season of 1903 about 40 men wo...
