The Middle Fork Willamette River and Coast Fork Willamette River define this portion of the Willamette Valley, where small agricultural and residential hubs like Pleasant Hill and Cloverdale are situated among prominent topographic rises. Local genealogy is well-preserved through several community burial grounds, including Mulholland Cem, Pleasant Hill Cem, Sellers Cem, and Cloverdale Cem. The landscape is a mix of river bottomlands and isolated volcanic plugs such as Sellers Butte and Rattlesnake Butte. To the west, the edge of Creswell appears near the confluence of Camas Swale Cr and the river, while Jasper sits at the northern reach near Hills Cr. The detailed road network, including the historic Immigrant Rd and Jasper-Lowell Rd, illustrates the transition from valley floor settlements to the rising timberlands marked by Short Mtn and Round Mtn.
