IDENTIFICATION OF WOOD AND CHARCOAL FROM MENLO PARK, CALIFORNIA, FOR THE SFPUC BAY TUNNEL PROJECT

Charcoal and wood fragments were submitted for identification from Menlo Park, California. These charcoal and wood fragments were found with hide fragments at a depth of 90 feet below the floor of the San Francisco Bay at the San Francisco Public Utilities Commission Bay Tunnel Project’s Ravenswood Shaft. Because samples were waterlogged, they were frozen prior to submission.
