Between the trees, spring and summer snowmelts sometimes fan out to form lush, though delicate, meadows. In this region, visitors often see mule deer, Douglas squirrels, and American black bears, which sometimes break into unattended cars to eat food left by careless visitors. There are plans to reintroduce the bighorn sheep to this park.The last California grizzly was killed in this park in 1922 (at Horse Corral Meadow). The California Black Oak is a key transition species between the chaparral and higher elevation conifer forest.
