Chimney Rock is a mountain located in the Alpine Lakes Wilderness of the Central Cascade Range in western Washington, United States.

However already on August 27, 1930, Forest Farr, Art Winder and Laurence Byington reached the summit via the south and east face, spending several days for exploration, in a feat quite remarkable for the time.

[6] Geological events occurring many years ago created the diverse topography and drastic elevation changes over the Cascade Range leading to the various climate differences.

[7] In addition, small fragments of the oceanic and continental lithosphere called terranes created the North Cascades about 50 million years ago.

[7] During the Pleistocene period dating back over two million years ago, glaciation advancing and retreating repeatedly scoured the landscape leaving deposits of rock debris.

Uplift and faulting in combination with glaciation have been the dominant processes which have created the tall peaks and deep valleys of the Alpine Lakes Wilderness area.
