SRSinc conducted seven surveys of adjacent parcels in Kern County, Tehachapi Mountains, totaling 6000+ acres of land. The Cummings Ranch was the largest parcel including 5120 acres on Cummings Mountain. SRSinc employed an unusual method of surveying large-acre areas, namely 'horseback' surveying. In reality, mules or donkeys are better animals for surveying very rough terrain but horse, mules, or donkeys are all superior to surveying on-foot. The animals can climb areas that are considered dangerous for humans and the rider can view the ground from a height close enough to see small objects, but far enough away to avoid snakes and the fatigue of climbing in and over boulder fields. This survey technique has been utilized by BLM, the Army Corps of Engineers, along with private landowners in San Diego, Riverside, Los Angeles, and Kern counties.
In addition to the horseback surveying, the ranch buildings themselves were evaluated for historic eligibility for listing on the National Register of Historic Places. The inventory and historic assessment included an 1854 miner's log cabin with adobe fireplace. In 1910, a half-finished barn was begun and discontinued, which reflected a change in the ranch's character; a gradual decrease in the number of horses made the need for the barn obsolete. A granary built in this same year reflects an increase in agricultural endeavors and was built for storing wheat and barley for cattle enterprises. In addition, the family owned and operated a small sawmill. The remains of the buildings forming the complex were found and documented extensively. The Cummings Sawmill Complex included a white pine structure [ca. 1920] that was indicative of a house occupied by a sawmill family. A house previously destroyed by fire still retained corrugated roofing and pipes and pipe frames representing the remains of the sawmill's foreman's house. An adjacent bunkhouse [ca. 1910] originally contained six or seven rooms that provided housing for the single mill hands, and the last structure in the complex was a dilapidated cookhouse from the same era. Several trash pits were found associated with these structures and included materials ranging from 1914 through the 1920s. Approximately a half-mile from this complex was an area with historic wagons and farm implements that were also documented. In the 1980s the Cummings Ranch was still a working cattle ranch, but it also provided living museum of the changes in commercial enterprises in Kern County.
