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
- NORTH CASCADES NATIONAL PARK
- Site is forested and more than 25 percent is covered with trees
- Site typically is on west slope of North Cascade Mountains, but areas are throughout the mountains
- Site is in many landscape positions at middle elevations (2,200 to 4,600 feet above sea level). It is cold and moist with snow commonly persisting until late in spring or early in summer. Pacific silver fir and western hemlock are common trees. Black huckleberry, false azalea, oakfern, and queenscup beadlily are common in the understory. If yes, the site is Low Cryic/Udic West Coniferous (F003NX924WA).
