Landsliding associated with coastal erosion has exposed an angular unconformity between weathered siliceous sedimentary rock of the Monterey Formation and by gravel of an ancient marine terrace. The gravel below the dark gray-brown sandy soil of the marine terrace deposits contain gravel clasts derived mostly from the Point Reyes Conglomerate of Galloway (1977). The conglomerate is missing from this area, but is exposed nearby near the Lighthouse on Point Reyes. Note the wind blown sculpted trees. Wind is a significant force of erosion along this exposed cliffy coastline. Uplifted marine terraces help geologist measure the rate of uplift along rising sections of the coastline. The Historic Point Reyes Lifeboats Station is in the distant left.
