Horse Spring Coulee Unit

Located 3.5 miles west of Tonasket, the Horse Spring Coulee Unit consists of approximately 850 acres. The terrain is predominately south-facing rolling sagebrush-steppe with rock outcroppings scattered throughout. Narrow, rocky valleys run north-south through the middle of the unit and eroded sandstone hills can be found in the northeast corner of the property, which is also the unit’s highest point. Elevation ranges from about 1,400 feet to 2,200 feet.

Habitat types include sagebrush steppe and dry grasslands – no trees are found in this unit. The property was purchased in 2008 primarily for critical mule deer wintering habitat. The Horse Spring Coulee Unit has a variety of wildlife species including: mule deer, whitetail deer, song birds, various raptors, coyotes, badgers and numerous reptiles. Wildflowers and native grasses are plentiful in the spring and early summer making for a very scenic landscape. Hunting and horseback riding are popular activities on the wildlife area as well as hiking, wildlife viewing, and nature photography.
