CourseEdit
It has its source on the southeast flank of Mount Oso, in Stanislaus County. From there it flows northwest then north through Hospital Creek Canyon around Mount Oso into San Joaquin County. It then turns east to dip back briefly over the border into Stanislaus County before turning back north into San Joaquin County flowing tnen northeast to emerge from the Diablo Range foothills.
From the canyon mouth it flows east into the Central Valley of California, United States. Though its downstream end is uncertain as it disappears into a former slough of the San Joaquin River in the San Joaquin Valley in Stanislaus County.
HistoryEdit
Originally called Arroyo de Ospital in the Diseño del Rancho Pescadero, this creek was a watering place on the El Camino Viejo. A map of routes to the southern gold mines in 1851 showed this creek as Arroyo del Osnital. Neither Ospital or Osnital is a Spanish word, so presumably it was a Native American word, probably Yokutsan. By 1857 Britton & Rey's Map Of The State Of California referred to the creek as Arroyo de Osnita. However by 1873, its name was changed to what it closely sounds like in English and was referred to as Hospital Creek on an official state of California Map. The only man ever to successfully navigate a large portion of this waterway is 5th generation Vernalis resident, David Patrick Thoming on February 11, 2017. The winter of 2017 proved exceptionally wet, and Thoming was able to kayak from the underpass of the California Aquaduct to the end of the creek at Welty Road; a total of 2.65 miles.
GeologyEdit
East of the San Joaquin Fault in the vicinity of Hospital Creek there is a flow pattern of alluvium that has been reported as a mud flow. This flow pattern was deposited in the early Holocene or the late Pleistocene.
