About this map

The timbered uplands of Columbia County take center stage in this 1990 revision, where the headwaters of the Clatskanie River and Milton Creek carve through the landscape. The small settlement of Trenholm serves as a local crossroads at the intersection of Trenholm Road and Pittsburg St Helens Road. To the north, the community of Beaver Homes and the nearby Whitney Basin illustrate the area's established rural character. The map details an extensive network of logging and access roads, such as Meissner Road and Canaan Road, which reflect the region's enduring connection to the forestry industry.

Water management is prominent in the southern portion of the quadrangle with the Salmonberry Reservoir situated along Salmonberry Creek. Local landmarks like Meissner Lookout and Serafin Point provide orientation across the ridgelines, while small-scale industrial activity is evidenced by scattered Quarry and Gravel Pit notations. This survey effectively documents the transition between the agricultural pockets of Canaan and the more remote, stream-cut valleys of Goble Creek and Tide Creek.
