- Goat Rock Beach
Russian River at the
Pacific Ocean.] Goat Rock Beach is a sand beachin northwestern Sonoma County, California, United States.This landform is a sub-unit of Sonoma Coast State Beach, owned and managed by the State of California. At the northern terminus of Goat Rock Beach is the mouth of the Russian River and the southern end of this crescent shaped expanse is the massive Goat Rock, an iconic outcropof the Sonoma Coast, which is barely attached to the mainlandby a narrow isthmus.
Goat Rock Beach is frequented by beachcombing visitors, but usually not in high numbers except in mid-summer; there is some wading and surfing activity, although these uses are moderated by the legendary
rip currentgenerated by a steep gradient into the water that leads to an underwater trench parallel to the waterline. The beach is also a regular resting ground for seagulls, harbor seals, and sea lions, the latter two speciessometimes hauling out of the Pacific Ocean. The state of California recommends that a convert|50|yd|m|adj=on distance be preserved between human visitors and the seasonal marine mammals, especially in the pupping season.
The Russian River, with its mouth at the north end of Goat Rock Beach, is Sonoma County's largest
watercourseboth in flow rate and lineal extent. Immediately beyond the Russian River discharge to the Pacific Oceanis the coastal town of Jenner. North of the mouth of the Russian River is Jenner Beach. Goat Rock protrudes into the Pacific at the south end of Goat Rock Beach. Visitors can access the base of Goat Rock via a low lying isthmusof land which has been appropriated by the State as a parking area. The almost sheer cliffs of Goat Rock are virtually impossible to scale or to circumnavigate; in fact, signage is posted prohibiting either activity. There is considerable sloughing of broken rock from these vertical surfaces of Goat Rock. Blind Beach is situated immediately south of Goat Rock Beach, the two beaches being separated by Goat Rock itself. Along Goat Rock Beach and the adjoining beaches, massive rock outcroppings are found both on the shore and protruding from the Pacific Ocean as small skerries. Among these rugged structures are natural arches formed by powerful wave action selectively eroding weaker strata of the rock formations. Approximately seventeen miles to the south is another major geologicalfeature of the Northern California coastknown as Bodega Head. Goat Beach lies below and slightly west of State Route 1.
Goat Rock Beach is subject to continuing marine
erosionas well as windborne erosion, thus creating a situation where an average of one to three feet per year of land mass is lost, [http://baynature.org/articles/jul-sep-2001/goat-rock-state-beach Doris Sloan, "Goat Rock State Beach", Bay Nature, July-September, 2001] ] except for the hardest of outcrop formations . In winters of heavy storms this value can be yet higher. Over the last geologic epoch the land has been subject to uplift, [http://http://baynature.org/articles/jul-sep-2001/goat-rock-state-beach Doris Sloan, "Goat Rock State Beach", Bay Nature, July-September, 2001] ] a process combined with marine erosion, which has created a marine terrace above the entire extent of the beach. This marine terrace elevation varies approximately 30 to 150 feet (10 to 50 meters) above mean sea level, which results in a steep bluff directly above the littoralzone, and a succession of terrace levels.
The sea stacks along the coast at Goat Rock Beach consist of rocks from the
FranciscanComplex, formed within an era of plate collision along the western coast of North America. From about 200 to 30 million years ago, the North American Platewas in continual collision with the Farallon Plate. [Bay Nature, Winter 2001] . A variety of rock types resulted from this collision, including pillow basalt, chert, and marine sandstone. During the plate collisions, these rocks were considerably faulted and crushed into melange, which is a mixture of ground-up matrix and resistant pockets of rock floating within. When melange is eroded by wave action, the softer part of the matrix is washed away, leaving the more resistant blocks exposed in the ocean as sea stacks. Goat Rock is such a flat topped [ [http://www.californiacoastline.org/cgi-bin/image.cgi?
] ] sea stack comprised by a block of resistant
Vertical sea stack formations, a geological hallmark of this shoreline, appear standing out of the water or on the
beachresembling sculptures. Occasionally these stacks appear on the marine terrace, indicating their ancient genesis on the sea floor prior to uplift. These rock formations are characteristically composed of sandstonewith layers of quartz.
San Andreas Faultruns roughly parallel and near to the coastline of Goat Rock Beach. Soils within the site are classified as coastal beach sands (where rocky shoreline is not evident) and escarpmentgroup soils on the marine terrace; typically soils above the marine terrace are in the Rohnerville loam group. ["Soil Survey, Sonoma County, California", U.S. Department of Agriculture, Soil Conservation Service, Government Printing Office, Washington DC, May 1972] Most of the beach sands consist of a medium coarse brown to gray sandy materials, reflecting the high rate of erosion of escarpmentsoils into the ocean; however, there are patches of dark gray smooth pebblebeach such as the approximately one hundred meter stretch lying immediately north of Goat Rock.The beach is changed every year.
natural historyof this area related to mammals manifests in a series of rock outcrops about one third of a mile south of Goat Rock Beach, positioned above the shoreline on a low lying marine terrace. There are uplifted sea stack formations with prominent rubbing marks about two to four meters in elevation above the ground surface, a height too high to have been caused by modern bovids. Mammoths are believed to have roamed here as recently as 40,000 years ago, and they are thought to have created these severe rubbing marks [E. Breck Parkman, "Mammoth Rocks: Part 1, Where PleistoceneGiants got Good Rub", Center for the Study of the First Americans, Mammoths Series, Volume 18, Number 1, December 2002] . Mammoth fossil remains have been found at Bodega Headat the south end of Sonoma Coast State Beach.
The earliest known human settlement of this site was by the Native American
Coast Miwokand Pomotribes. As early as 1849 archaeologicaldiscoveries were recorded in the vicinity, and to date several prehistoric kitchen middens and other types of tribal habitation finds have been made. Goat Rock Beach is part of a Mexican land grantcalled Bodega Rancho[Rex Grady, " Let Ocean Seethe and Terra Slide: A History of the Sonoma Coast and the State Park That Shares It's Name"] . The Russiansare thought to have begun logging the old-growth forests directly above the coastal prairie in the early 19th century.
The underwater delineation of the property is considered to extend to 1000 feet from the
shoreline. While no shipwrecks have been discovered, the literature indicates that there are at least 17 vessels which may have been lost in these waters. There are remains of numerous historic barns and other agriculturalbuildings on the coastal prairie several miles south of Goat Rock Beach, indicating 19th century settlement by Europeans; to the south, at Duncans Landingthere are iron pins embedded in the sandstone bluffs as evidence of an active shipping industry here in the late 19th and early 20th century.
In the era circa 1920, a sizeable
quarrying was conducted at Goat Rock, which activity produced the apparent separation of Goat Rock from the mainland. Quarry products were transported to the mouth of the Russian River via a now abandoned rail line; some of these materials were used to attempt the construction of a jettyin the mouth area, but that project was eventually terminated.
Flora and fauna
There are three distinct
habitats present at Goat Rock Beach, including marine, littoral zoneand coastal prairie. The marine environment presents gray whales, harbor seals [ [http://www.parks.ca.gov/?page_id=451 California State Beaches: Sonoma Coast State Beach] ] and California sea lions as well as a multitude of fish speciesand other marine organisms; in fact, several species of anadromousfish enter the Russian River estuaryand migrate for tens of miles up the Laguna de Santa Rosaand other Russian River tributaries. [David Cook and Jessica Martini-Lamb, "Copeland Creek Restoration Project Monitoring Plan",Sonoma County Water Agency, April, 2001] . Furthermore, a variety of pelagicbirds and shorebirds are locally in evidence. Additionally there are modest kelpbeds and other marine vegetation. The littoral beach environment has fewer organisms than more southerly zones of California, because of the colder temperatures here.
The coastal prairie soils on the marine terrace above the beach are moderately well drained and granular with moderate soil permeability; these features manifest high erosion potential and moderately high bio-productivity.
Acidity of these loamy soils is medium to high, and thus some vegetative stunting and hospitality to rare plants is offered; however the tree stunting is not as pronounced as farther north along the Mendocino coast, which presents extensive and exaggerated pygmy forests. The upland environment on the coastal prairieoffers a range of grassspecies and wildflowers including varieties of lupine, thistleand wild oats. The typical annual plant productivity is approximately 1500 kilograms per acre of air dried yield per annum in an abundant moisture year, and about half that amount in a very dry year. A variety of birds and mammals thrive on the coastal prairie including numerous California Mule Deer, "Odocoileus hemionus californicus".
Due to these potential safety risks of the rip currents at Goat Rock Beach, swimming is strictly prohibited. There are restroom facilities, a parking lot, and picnic tables on site. [ [http://www.russianrivertravel.com/parks-sonomacoast.htm Sonoma Coast State Beach: Goat Rock Highlights] ] .
