Additional information will be added as it becomes available. Stands are found at high elevations (2710-3110 m [8900-10,200 feet]) on gentle to steep slopes (3-27°). Slopes are concave in shape. Aspect ranges from west to northeast; however, it is often northwest. These sites can be rocky. Soils are poorly developed to well-developed with textures that range from rocky gravel to rock, gravelly, sandy loam. Soils are well-drained with soil depths ranging from shallow to deep. Parent material is granite. Fire is uncommon and restricted in size. Disturbance levels are usually low. Stands are characterized by <i>Tsuga mertensiana, Pinus contorta</i>, and <i>Pinus albicaulis</i> in the overstory. <i>Juncus parryi</i> and or <i>Juncus</i> sp. are often present in this association.
