57 ALPINE ZONE The alpine zone occurs in high mountain areas where the mean annual precipitation is above 41 inches and the RET is the lowest in the state (Figure 7.6). These areas occur above the upper timber line. The vegeta-tion consists mainly of small cushion plants on rocky slopes.
Alpine asters (Aster alpines) grow to a height of 6 to 12 inches and bloom from mid-spring to early summer. Their daisy-type, 1-inch-diameter flowers have purple-blue petals and yellow centers.
