Cougar sits at the northern end of Yale Lake, serving as a gateway to the volcanic landscapes of the Mount St Helens National Volcanic Monument. The late 20th-century landscape is defined by its recreation-oriented shoreline and industrial water management, featuring several designated campsites such as Beaver Bay Campground and Cougar Campground. This area of Cowlitz County shows a clear division between the protected wilderness of the Gifford Pinchot National Forest and the developed access points along the Lewis River.
