The Matanuska-Borough’s Jim Creek parcel’s natural character is heavily influenced by the dynamic Knik River, the Knik Glacier, and the Chugach Mountains. Soils are glacial, including gravelly till and outwash, overlain by shallow to deep silty soils. Stream bank and wind erosion are active on uplands directly adjacent to the Knik River.

A network of motorized trails threads through the Jim Creek Recreation Area, providing a maze of fun for ATVs, dirtbikes, and pedestrians. Trails include the Tech Trail, as well as the Envy and Sexton Trail which connect to the Jim Creek/Knik Glacier Trail.

Trash, broken glass, and unauthorized fire pits are a common sight within Jim Creek Recreation Area. Please have caution with children and dogs.
