West Fork Little Delta River anchors the southern drainage of this Interior Alaska landscape, where a braided river system cuts across the lower elevations near the O'Brien Cr confluence. The terrain is defined by dramatic elevation changes and a series of north-flowing seasonal and perennial streams, including the steep-sided valleys of Portage Cr and Iowa Cr. This 2016 survey illustrates the intricate drainage patterns of the north-central Alaska Range, including smaller tributaries like Whiskey Pup. The map serves as a primary record of the hydrography within the Denali Borough, capturing the untouched wilderness before it reaches the Tanana Valley to the north.
