About this map

Hemlock Pass serves as a central landmark in this portion of Cowlitz County, where the terrain is defined by a dense network of drainage systems feeding the Coweeman River. The landscape reveals a pattern of industrial land use, notably indicated by several Borrow Pit excavations situated near the ridgelines. Waterways like Hemlock Creek and Mulholland Creek carve through the high elevations, illustrating the complex watershed geography of the Pacific Northwest.

The western edge of the map is marked by the Willamette Meridian, a critical surveying line for land claims and property boundaries in the region. Near this boundary, the small settlement of Ostander appears along the valley floor. Researchers will find interest in the numerous named tributaries, such as Sam Smith Creek and North Fork Goble Creek, which provide specific geographic anchors for 20th-century land use and family history studies.
