The divide between Coos and Douglas counties is defined by a series of prominent elevations and creek drainages in this modern topographic map. Centered on the namesake Ivers Peak, the landscape is dominated by the sprawling headwaters of the East Fork Millicoma River and the complex drainage systems of Matson Creek and its southern and little forks. The boundary between the counties follows the winding crests of Coos Ridge and High Ridge, marking the transition into the Umpqua National Forest at the northeastern corner. This area is characterized by heavy timberland management, evidenced by the presence of numerous forestry access routes like BLM Rd 24-8-35.1. The terrain is deeply incised by Beulah Creek, Fall Creek, and Bear Camp Creek, illustrating the drainage patterns that define this section of the Oregon Coast Range before these waters reach the lower valleys.
