Hikers and amateur rock hounds enjoyed a geology walk through Tucker Wildlife Sanctuary and up the Harding Truck Trail on Aug. 4.

Bud Benneman, geology instructor at Golden West College, discussed the formation of the Santa Ana Mountains. He told the group about local landforms, erosional patterns on the landscape and current faults. The program included samples of rocks and minerals.
