1979 Map of Stony Mountain

About this map

Tillamook State Forest covers the northwestern corner of this territory, where the boundary between Tillamook and Yamhill counties cuts through the timbered heights of Stony Mountain and Green Top. The landscape is defined by its drainage network, with the steep headwaters of Baltimore Creek, La Toutena Mary Creek, and East Creek flowing south toward the Willamina Creek valley. A distinct shift from timber to agricultural land occurs in the southeast, particularly along the fertile banks of Gopher Valley Creek.
