History of the Sweet Springs Site - from ~500 AD to 2017
Archeological artifacts indicate the area where Sweet Springs is located was originally settled by the Chumash as early as 500 AD and they lived there through the late 1700s. The area was subsequently “discovered” by the Spaniard Captain Gaspar de Portola during the ‘Sacred Expedition,’ from Mexico through San Diego to Upper California, from 1769 to 1770.

East Sweet Springs 2017 Expansion Project
The Morro Coast Audubon Society acquired the 8.3 acre East parcel in 2008. In 2011 MCAS applied to the County of San Luis Obispo for a minor use permit (MUP) allowing for native plant restoration and public access project at East Sweet Springs. In 2017 the MUP was approved and East Sweet Springs was improved with boardwalks, signage, benches, viewing blind, and more. Together with West Sweet Springs and Central Sweet Springs, the Sweet Springs Nature Preserve will continue to be a place to walk, watch birds, and enjoy a quiet and a peaceful natural environment.
