Geology and ground-water resources of the Matanuska Valley agricultural area, Alaska

The Matanuska Valley is a part of the lowland lying north of the Chugach Range in south-central Alaska. The valley of Matanuska River and the lowland extending westward from it to the Susitna River are in the Matanuska and Wasilla districts as defined by P.S. Smith (1939, pl. 3). The area described by this thesis, hereafter termed the Matanuska Valley agricultural area, is best known as including the site of agricultural colonization undertaken by the Federal Government in 1935. It is bounded on the north by the Talkeetna Mountains and Little Susitna River, and on the south by Knik River and Knik Arm (plate 1). It lies between Eska Creek on the northeast and Goose Bay on the southwest. As thus defined the area lies approximately between 148°55' and 149°50' west longitude and between 61°25' and 61°45' north latitude; it covers about 350 square miles.
