What stands out about Dorrington’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
Originally known as Cold Springs Ranch, the town's name changed upon establishment of the post office in 1902. The name Dorrington comes from the maiden name of Rebecca (Dorrington) Gardner. Famed naturalist John Muir visited a large Sugar Pine Tree here on August 22, 1900, with C. Hart Merriam and Florence Merriam Bailey on a trip between Lake Tahoe and Yosemite. The post office was discontinued in 1919, but re-established in 1921 and closed for good in 1934.
