Arch Rock Trail -
This unique natural formation was found during the great Sardine Creek fire of 1951. The arch stands fifty feet tall and forty feet wide.
Thousands of years of natural weathering caused the rocky material to fracture and break apart. This process created the arch and its tiny caves that are found around the base of this impressive structure.
