About this map

French Mountain and Olallie Mountain anchor this high-elevation landscape within the Cascade Range of Lane County. The drainage network is defined by the East Fork South Fork McKenzie River and its numerous tributaries, including French Pete Creek, Olallie Creek, and Horse Creek. These waterways carve through a complex system of peaks and ridges, including the prominent formation of Taylor Castle and the nearby Lamb Butte.

Glacial and volcanic history is evident in the grouping of small water bodies like Karl Lake and Ruth Lake, as well as the unique geological area known as The Potholes. For researchers of the Oregon Cascades, this 2011 survey documents a terrain characterized by high meadows such as Wolverine Meadow and Pothole Meadow, illustrating the natural water-retention basins vital to the regional watershed before they descend into the deep river valleys.
