Description
The Agiapuk, flowing into Imuruk Basin from the north, drains an area of from 800 by 1,000 square miles (2,100 km2 × 2,600 km2) in the center of Seward Peninsula. The river forks about 20 miles (32 km) north from Imuruk Basin, the eastern and larger branch being called the American River by the prospectors, while the western branch retains the name Agiapuk. Below the forks, the Agiapuk makes many meanders on a broad flood plain, from which the upland rises by gentle slopes to flat-topped hills with elevations of 600–800 feet (180–240 m).
