About this map

Elochoman Pass sits at the southern edge of this heavily dissected landscape, marking a significant topographical transition where the headwaters of several major river systems converge. The terrain is defined by the intricate drainage networks of the Chehalis River, including its E Fork Chehalis River and W Fork Chehalis River, which carve deep valleys across the central and northern sections. This 2017 survey illustrates a wild, mountainous region primarily used for timber resources, evidenced by the dense network of unnamed forest roads winding through the ridges.

To the west, the E Fork Grays River and S Fork Grays River flow toward the coast, while the N Fork Elochoman River begins its descent from the pass. Natural transit points like Sage Creek Low Gap provide the only breaks in the high ridges, such as those separating Smith Cr and Thrash Cr in the northern reaches. The map captures the meeting point of Pacific, Lewis, and Wahkiakum counties in a landscape dominated by industrial forestry rather than permanent settlement.
