COMMISSION

Because of this evaluation, the ASC identified the Tesla Mining and Industry historic district.
This historic district is a large and diverse property comprised of 34 known resources, and
encompassing 680 acres within Carnegie SVRA and adjoining OHMVR Division-owned
properties. The overall historic context of the historic district is mining in Corral Hollow from
1855 to 1911. Within that larger context, each of the contributing resources is associated
with one of the following themes or sub-contexts:
•§
early coal exploration and mining, 1855-1866;
•§
the San Francisco and San Joaquin Coal Mining Company, 1890-1905;
•§
sand mining for the Pacific Window Glass Company, 1890-1908; and,
•§
clay mining for Carnegie Brick and Pottery Works, 1901-1911.
The contributing resources to the historic district include the following: Carnegie Water
Works Mine, Tesla Complex, Ryan Clay Works, Tesla Sand Mine, Alameda Mine,
Harrietville, Historic-era Artifact Concentration/Cabin Flat, Harrisville, Commercial Mine
(Main Shaft), Pottery Sewer Pipe Plant, Coast
Range Coal Mine, Alameda-San Joaquin Railroad,
Tesla-Livermore Road, Hetch Hetchy Work Camp,
Tesla Clay Works, Summit Mine, Carnegie Lime
Kiln, Commercial Mine (Meader Shaft), Three Lime
Kiln Prospect Cuts, Carnegie Road (Lime Kiln), and
the Carnegie Brick and Pottery Company.
On December 7, 2012, the State Historic
Preservation Officer (SHPO) concurred with the
ASC’s determination that the Tesla Mining and Industry historic district is eligible for listing
in the NRHP at the state level under Criteria A, B, C, and D, with a period of significance of
1855 to 1911. An official nomination to the NRHP is currently planned.
Two prehistoric resources, CA-ALA-443, a prehistoric occupation site with evidence of inter-
tribal trading and CA-ALA-571, a prehistoric rock art site, were also recorded and evaluated
by the ASC. The ASC concluded that both of these resources are eligible for the NRHP and
the CRHR for their ability to yield significant information about the prehistory of the area. On
October 9, 2013, SHPO concurred with the determination that CA-ALA-443 is eligible for
listing in the NRHP under Criterion D and CA-ALA-571 is eligible under Criteria C and D.
In 2012, two historic-era buildings—an operations building also known as Building C and a
building referred to as the Gorman House—located at Hungry Valley SVRA were recorded
and evaluated by OHMVR Division archaeologists and historians with the Southern Service
Center of State Parks as part of the environmental review for a proposed project. The
evaluation determined that both buildings are ineligible for the NRHP or the CRHR and the
findings are currently being reviewed by the SHPO.
