ARCHIVES SEARCH REPORT – FINDINGS
Jenner 12th Naval District Target No. 29
Jenner, CA
An ASR site inspection is limited in scope to a visual, non-intrusive inspection of the
areas suspected of having an OE or CWM hazard potential. This potential is based on an
analysis of the collected information. Prior to the inspection, the Archive Search team
determines the areas of the site to investigate. The team follows a Site Safety and Health
Plan (SSHP) prohibiting digging or handling of potential OE and CWM. The SSHP
defines standard operating procedures to ensure safety and prevent accidents. Appendix
L-1 contains a copy of the SSHP. The inspection team consisted of the following St.
Louis District Corps of Engineers personnel: Alix Borrok, Randal Curtis and George
Sloan. They performed the site survey on Tuesday, 28 August 2001 in the afternoon.
Subsection 6.2 contains a synopsis of the site inspection and Appendix L-2 contains a
detailed account. Appendix I includes current site photographs.
6.2 SITE INSPECTION SYNOPSIS
The team traveled to Jenner, California to begin an inspection of the site, which is part of
the Sonoma Coast State Beaches, Russian River/Mendocino District and open to the
public. The 1945 aerial imagery clearly showed the location of a 100-foot diameter
boardwalk ring between Peaked Hill and several rock outcrops rising above the
surrounding ground. The team began their traverse of the site from Goat Rock Road, just
off California Highway 1, about a quarter of a mile from the target center. The ASR
team used a GPS to help reach the site. ii The majority of the area consists of pasture
grasses less than knee high. A smaller portion of the area gets more drainage and
consists of much thicker and taller grasses and shrubs about waist high. The grasses
partially obscured the ground. The team crisscrossed the target center and the
surrounding area for a couple hundred feet, but did not find any evidence of the target
such as weathered wood posts or OE debris of any kind. The team followed a slightly
different path in departing the site.
ii Target feature coordinates were determined using georeferenced historic aerial imagery. The resulting
waypoints were uploaded into a Garmin Etrex Legend GPS (Global Positioning System) receiver using
mapping datum WGS 1984
