T he rocks at Pinnacles are so spectacular in appearance because they have been exposed to so much eroding activity. This grand old volcano is but a pittance of its long ago grandeur. It is now like a playground volcano, left over for us to climb around in and learn about these geologic behemoths that blast out of the earth's furnace. Part of the original Pinnacles can be seen down by Lancaster along Hwy 138. H iking and climbing are chief objectives for visitors to the Pinnacles.
Fascinating trails abound.
There are four self guided nature trails. Get up close to strange, deep-red rocks. One is eleven miles, a roundtrip to the Chalone Peak that gives great looks at the rock formations, and an amazing view at the top. The Geology Hike and Balconies Trail are good learning experiences. Wherever you go, take a flashlight and water.
