Mount Saint Helens Wildlife Area
Mudflow Unit
This 2,744-acre unit is located in Cowlitz County along the North Fork Toutle River adjacent to the Mount St. Helens National Volcanic Monument. The unit was established in 1990 to protect elk winter range on the North Fork Toutle River mudflow that resulted from the 1980 eruption of Mount St. Helens. Most of the property was acquired through a land exchange with the Weyerhaeuser Co., with assistance from the Rocky Mountain Elk Foundation. Extensive efforts have been made to improve elk winter forage, including constructing erosion control structures, weed control, and vegetation plantings. This unit is part of the Mudflow elk area, which allows elk hunting by special permit only. All other hunting is restricted on the area.
