Camelback Mountain (Precambrian granite)

Camelback Mountain's distinctive profile is formed from exposed Precambrian granite and metamorphic rock estimated to be about 1.5 billion years old. The Echo Canyon Trail takes hikers across steep granite slabs, fractures, and exfoliation surfaces that define the mountain's rugged rock faces. The granite outcrops are a primary reason the mountain is a popular local destination for scrambling and rock-hold climbing.
