Cowlitz Chimneys is a cluster of four rhyolite towers in Mount Rainier National Park, part of the Cascade Range in Washington. Rising near Tamanos Mountain and Banshee Peak and visible from the Sunrise Historic District, the towers were formed from resistant volcanic rock left standing after surrounding material eroded away, creating their steep, isolated shape. The highest summit, the Main or South Cowlitz Chimney, reaches 7,605 feet, with the others somewhat lower. On the north side lies the Sarvant Glacier against remnants of a volcanic plug. The name Cowlitz was recorded as early as 1805 in the Lewis and Clark journals, and runoff from the towers drains to the Cowlitz River.
