Cultural Resources Review Results #5, January 22, 2021

INTRODUCTION

Dredged material is processed according to the Level 1 Archaeological Monitoring protocol outlined in the draft Cultural Resource Monitoring Plan (revised September 2020). This protocol calls for dredged soft sediments to be placed directly into barges, floated to the processing facility, and screened over bars on a vibrating platform. Items removed during the vibratory screening process are then sorted by trained personnel as per the draft Cultural Resource Monitoring Plan. Items of potential interest (possible artifacts or objects of local interests) are placed in a separate stockpile and photographed for archaeologists to review. These items are then placed in a holding area for archaeologists to inspect. To date, the vast majority of the recovered items consisted of modern debris and timbers.

RESULTS

An archaeologist conducted a scheduled visit at the dredge material processing facility on 1/22/21 to review the recovered items in person with the assistance of a dredge material processing facility machine and operator to sort through stockpiled items. Photographs were taken of stockpiled items.

The recovered items were spread by machine on a flat hard surface to allow for an archaeologist to clearly review them, (Photographs 1 through 6). Any item of potential interest was separated, rinsed and assessed. The majority of the items reviewed were separated into two piles: debris and tires (Photographs 1-2). The majority of the debris reviewed consisted of modern material, including car parts (Photograph 3), wood and timbers (Photograph 4), large concrete blocks (Photograph 5) and pipes (Photograph 6). No items were recommended for retention.

ITEMS SEPARATED FOR FURTHER REVIEW

The archaeologist did not encounter any items to retain for further analysis.

CONCLUSIONS AND RECOMMENDATIONS

The archaeologist concludes that no items observed during the sediment screening at the dredge material processing facility retain possible historic/archaeological significance. Per the draft Cultural Resource Monitoring Plan, the archaeologist further recommends that all the non-historically/archaeologically significant debris that has been reviewed by the archaeologist as of 1/22/21 may be disposed of.
