Archaeological Survey

Graveyard Survey

The survey crew works on a cold January morning

"The geophysical survey did not find conclusive evidence for a mass burial, as hypothesized by local legend. However, there is one potential area within the survey block that may contain unmarked burials and should be confirmed via ground truthing. . ." — Molly Cannon, Ph.D.

Ground penetrating radar was used to visualize the surfaces throughout the area, including below ground. Magnetic gradiometry produced a dense dataset to detect small subsurface features. The use of two different instruments helped researched more accurately identify what they found.

Graveyard Recommendations

At left, the portion in red is where the possible unmarked burials are situated. The green space is suggested as a place where new graves could go.

Could the unmarked burials be Chinese workers? There's no way to know from surface surveys.
