    Below is Russian Gulch Bridge (aka Frederick W. Panhorst Bridge)at Russian Gulch State Park, and completed in 1940. It is located on Highway 1, just south of Jenner in Mendocino County in California. The bridge is built on Franciscan formation graywacke.

    Greywacke is a poorly sorted sandstone containing grains of angular rock fragments. It is often called a "dirty sandstone" and formed from mud and sand-laden flows along steep continental slopes associated with, and swept up in the accretionary wedge along the former Mesozoic subduction zone and accreted to western North America.
