The CDF Archaeology program is participating in a
multi-agency, on-going research project involving an inventory of a fascinating
and enigmatic group of archaeological sites – the mysterious rock-basin sites
found in the Southern Sierra Nevada of California. A study group has been formed and is actively pursuing the
inventory. Our goal is to identify and
record all known rock basin sites, map them on a GIS database, determine the
northern and southernmost boundaries of the site cluster, field visit as many as
possible, and gather information on a number of selected site attributes. The inventory data will enable researchers
to more accurately describe this remarkable group of sites, and shall
facilitate additional research and interpretation. The inventory project is spearheaded by the Southern Sierra
Archaeological Society (SSAS). Linda
Sandelin (CDF) chairs the Basin Committee which includes agency archaeologists
Tom Burge (National Park Service) and Bill Matthews (USFS). Society members with considerable expertise
and interest in southern Sierra Nevada archaeology include Dave Dulitz, Mary
Gorden, Louise Hastrup, and others.
The inventory has resulted in the identification of
over 200 confirmed site locations, from the northern most sites in the Yosemite
area south into Kern County. Researchers
need consistency in both rock basin field methodology and terminology in order
for the sites to be adequately studied through the site records. Since many of these sites have been recorded
by non-archaeologists, SSAS has held several rock basin workshops where
professional archaeologists have trained the non-professionals in field
methodology for measuring and recording these enigmatic archaeological sites.
SSAS provides site recorders with geologically compatible basin terminology.
At Mt. Home Demonstration State Forest near Springville, Forest Manager Dave Dulitz has spearheaded several survey and recording projects leading to the documentation of 20 sites containing 135 rock basins within Mt. Home Demonstration State Forest and the immediate area (Fig. 1). The sites in the Mt. Home area are scattered over an area of approximately 15 square miles. Elevation of the sites range from 5,440 to 7,000 feet.

Fig. 1. This site in Balch Park, Tulare County, has
23 basins as well as 9 bedrock mortars.
The rock with nine basins appear to be set in a deliberate pattern.

and bedrock mortar site within Mountain Home Demonstration State Forest.
A GIS mapping project is underway thanks to Dulitz’s efforts of coordinating CDF personnel to provide GIS expertise. Mapping of these sites will include layers of information such as elevation, exposure, evidence of prehistoric activity, and proximity of Sierra redwood forests. We hope this project will allow us to be able to glean information on site patterning and distribution.
Foresters also are drawn into our efforts of
discovering new basin sites. CDF
requires foresters preparing timber harvesting plans to provide an
archaeological survey within the harvest plan area. Kirby D. Molen, a registered professional forester, recently
discovered a previously unrecorded rock basin site while conducting an
archaeological survey for a non-industrial timber management plan that he was
preparing in Madera County. This site
was then brought to the attention of CDF Archaeologist Linda Sandelin during
plan review. A field inspection
confirmed that Molen had indeed discovered a new rock basin site. Three members
of the inventory team (Sandelin, Matthews, and Burge) met on January 12, 2000
to survey and record the new discovery (Fig. 3). The site, named Lucky 13, consists of thirteen
distinctive rock basins clustered on an expansive granite outcropping. A description of the recently-recorded Lucky 13 site is also
posted on CDF’s Archaeology Program website.

linear patterned arrangement.
The Sunset Point Archaeological Site self guided tour is available in the Mt. Home Demonstration State Forest where you can learn about 8,000 years of prehistory at a high Sierran campsite. On this short hike you will see sign boards that discuss archaeological evidence from an excavation, the interpretation of this evidence, and a description of the basket making process. You will be able to see and feel bedrock mortars and rock basins.
Even though researchers can not substantiate the
natural theories, many researchers have rejected the suggestion that the Native
Americans painstakingly pounded out these huge depressions from solid bedrock,
though the possibility of a human origin cannot be completely discounted (Fig.
4, 5, and 6). Studies will soon be
underway at Mt. Home to determine if the theory that a combination of fire,
freezing water, and human carving of the rock will be able to recreate these
basins.

visible in the foreground. Notice the
forested setting in the background.

Fig. 6. This basin site also within Mountain Home Demonstration State Forest again illustrates a deliberate patterning of three basins in a line.
The Southern Sierra Rock Basin Inventory project is
an on-going research effort. As new
sites are located we will enter them into the inventory. There is no doubt this database will prove
to be useful to anyone conducting research on this remarkable group of features
and possibly lead to solving some of the mysteries surrounding their creation
and archaeological significance. Your help is truly appreciated; anyone knowing
about the location of a basin site is urged to contact Linda Sandelin at Linda_Sandelin@fire.ca.gov
