2011 Map of Elochoman Pass

About this map

Elochoman Pass serves as a central geographic landmark in this heavily dissected landscape, where multiple river systems originate and diverge. The area is defined by the headwaters of the Chehalis River, including its West Fork and East Fork, which flow alongside numerous named tributaries such as Big Roger Creek and Cinnabar Creek. The intricate drainage patterns shown here illustrate the watershed divide between the Chehalis basin and the rivers flowing south toward the Columbia, including the North Fork Elochoman River and the forks of the Grays River.
