South Mount Hawkins is located in the San Gabriel Mountains, and contained within the Angeles National Forest. The mountain was named after Nellie Hawkins, a popular waitress of the Squirrel Inn located on the North Fork of the San Gabriel River. Although the Squirrel Inn is long gone, Nellie has her name on Mount Hawkins and South Mount Hawkins. There are two ridge bumps between the two named summits and they are unofficially known as "Middle Hawkins" and "Sadie Hawkins". According to the California State Library, "Cold Brook Camp, located within the Angeles National Forest, [was] very popular with campers. Started out as hunter's camp owned by R.W. Dawson. In 1901, land leased to Doc Beatty who opened hostelry called Squirrel Inn. In 1907, Dawson took over the Inn renaming it Cold Brook Camp. Eventually built hotel, cabins and tents. Was popular in early 1900s and into the 1920s."
