Hamilton and the surrounding high country of Grant County are defined by a network of drainage basins and steep-sided ridges that descend toward the Fox Valley. This landscape, surveyed in the 1980s and 1990s, illustrates the complex topography where the Malheur National Forest meets private ranchlands. Named peaks like Hamilton Mountain, Sunken Mountain, and Table Rock dominate the horizon, while the drainage of West Fork Deer Creek and East Fork Deer Creek carve significant paths through the terrain. Evidence of local industry and rural life appears in the small settlement of Courtrock and the Cinder Pit near the northern edge. The map also records essential local landmarks for genealogical research, including a small Cem near the Hamilton townsite and the distinct geological feature of Eagle Rock situated above Long Hollow.
