Site 33-023901 was revisited during an intensive-level field survey on March 13, 2024, and was found to be largely in the same condition as originally recorded in 2014, although the orange grove and its trees appeared to show signs of neglect, while the modern features in the eastern portion of the site, such as the driveway and the sheds, had fallen into disrepair.
A notable discrepancy from the 2014 site record is the location of the master valve bearing the “SNOW MFG. CO., LA CAL” steel gate stamp. The site record indicates that it was found along Victoria Avenue , but the master valve encountered during the survey, which bears the same steel gate stamp and matches photographs in the 2014 documentation, is located in the eastern corner of the property, 110 feet southeast of the end of Millsweet Place and 630 feet southeast of Victoria Avenue. It is possible that a second master valve was once located along Victoria Avenue but has since been removed, but it seems unlikely.
The 2014 study found no evidence of any residential use of the property from historical maps or census data. Early aerial photographs of the property, however, demonstrate that what appear to have been a residence and an ancillary building were located near the western corner of the property in 1931 and 1938, although both were removed prior to 1948. No evidence of the buildings could be found at that location during the field survey.

Description: (Describe resource and its major elements. Include design, materials, condition, alterations, size, setting, and boundaries): This prehistoric isolate consists of a large portable granitic metate with two milling slicks. The metate measures 60.7 x 38.5 x 21.2 centimeters, with one s lick measuring 30.8 x 15.9 centimeters and the other
21.6 x 15.4 centimeters. Both slicks exhibit a moderate amount of polish with the high points noticeably worn down. The location lies in an orange grove that has been under cultivation since at least 1902, in close proximity to a dirt road and a concrete irrigation head. Given the clear evidence of past disturbances to the ground nearby, the artifact is unlikely to be in situ. At some point a cement mix was splashed on the artifact, probably during construction of the irrigation line, resulting in more than 17 pieces of hardened concrete affixed to its surface, including within one of the slicks. *P3b.
