Excerpt from The Tin Deposits of the York Region, Alaska The York Mountains occupy the southeastern part Of the triangle and culminate in Brooks Mountain, feet in altitude, the highest point in this part Of the peninsula. These mountains have rugged crest lines, their continuity being broken by several broad streams and river valleys, but when seen from a distance their summits have an even sky line from to feet above the sea. To'the north and west Of this mountain group stretches the so-called York Plateau, a comparatively smooth upland surface 200 to 600 feet above sea level that comprises the greater part Of the region under discussion. The smaller streams crossing this plateau flow in sharply cut V-shaped canyons, while the larger streams occupy comparatively broad valleys containing large accumulations Of gravel. On the south the plateau presents an escarpment. To Bering Sea, but on the north it slopes gently downward to a coastal plain dotted with lakes, through which the rivers and streams meander to the Arctic Ocean. The drainage of the region runs either northward or southward, but the watershed lies much nearer Bering Sea than the Arctic Ocean.
