Key Characteristics
- Site located north of the Columbia River.
- Within a national park soil survey or in an area joining with a national park in the Washington Cascades Range
- MOUNT RAINIER NATIONAL PARK
- Site is forested, and more than 25 percent is covered with trees
- Site is composed primarily of deciduous tree species in areas of active disturbance on mountain slopes and valley sides. Disturbances include rockfalls, debris torrents, and avalanches
- Site is at an elevation of 2,100 to 6,600 feet above sea level. The vegetation is primarily Sitka alder, vine maple, red elderberry, thimbleberry, salmonberry, and devilsclub. Repeated avalanches do not allow for the establishment of a forested overstory; however, seedlings of Pacific silver fir, noble fir, and western hemlock may be present. If yes, the site is Southern Washington Cascades Low Cryic Deciduous Forest (F003XN948WA).
