Abbotts Lagoon is a lagoon on the northwestern coast of the Point Reyes National Seashore, southwest of Tomales Point, in California, United States. The inland portion of the lagoon receives freshwater runoff, but the lagoon may be brackish from occasional winter tidal exchange along its western edge.[1] The eastern shore of the lagoon is covered with old growth northern coastal scrub including coyote bush, yellow bush lupine, sword fern and California blackberry.[2]

Geology

Abbotts Lagoon is usually separated from the Pacific Ocean by dune sand to the west. The eastern side of the lagoon is bordered by Miocene marine sediments to the north and Pliocene marine sediments to the south from sedimentary rock formations on the western side of the San Andreas Fault.[3] Santa Margarita Sandstone atop the Monterey Formation forms a ridge along the southern side of the valley containing the lagoon inland of the pedestrian bridge, and is exposed along the eastern shoreline of the lagoon seaward of the pedestrian bridge.[4]

History

Coast Miwok lived in the area before 19th-century European colonization. The lagoon land was used for cattle and dairy ranching by the 1870s.[4] Abbotts Lagoon was variously identified as Abbott's Lagoon Bombing Target, Abbott's Lagoon Target Area, Abbott's Lagoon Bombing Range, and Bombing Range Number Two while used as a dive bomber practice area by pilots from Alameda Naval Air Station and Santa Rosa outlying field from 1941 to 1952.[5] The lagoon was designated part of Point Reyes National Seashore in 1962.[4]

Recreation

Walking trails provide access to observe the birds and wildflowers of the locally unique habitats surrounding Abbotts Lagoon.[6] Brush rabbits, black-tailed jackrabbits, pocket gophers, muskrats, river otter and black-tailed deer may be seen around the lagoon. Coyote, bobcat, gray fox, long-tailed weasel, striped skunk, raccoon, badger, and cougar are rarely seen.[7]
