Lake Lawrence and the surrounding basin of Smith Prairie define the northern lowlands of this Thurston County landscape. The area is marked by a transition from residential developments and small airstrips like Cougar Mountain Airfield and the Flying B Airport into the steep, densely forested timberlands to the south. The upper reaches of the Deschutes River and the Skookumchuck River carve through the rising elevation, where prominent peaks such as Clam Mtn and Porcupine Ridge dominate the horizon.
