Twin Falls Soil Analysis and Drone Imagery Updates

Abstract

In 2021, Anatolijs Venovcevs and James Williamson conducted a one-week survey at the mothballed hydroelectric plant and associated community at Twin Falls, Labrador (Venovcevs and Williamson 2022) (Figure 1). The fieldwork provided detailed documentation on the industrial and settlement areas of the site through a UAV survey and surface documentation of visible remains while producing promising results from limited photogrammetry and test pitting. However, a few vital issues remained unresolved – namely a proper colour correction of the drone imagery, the original function of the remaining buildings, and the results of the soil samples collected from two test pits near Building 1. This report is meant to tie up those loose ends.
