The headwaters of the Cowlitz River are on the south slope of
Mount Rainier. The river flows southwest through
Packwood and
Randle, at which point it turns away from Highway 12. Two dams, Mayfield and Mossyrock, create reservoirs on the river. Below the dams, it flows past
Toledo,
Castle Rock, and between
Kelso and
Longview before joining the
Columbia River.
