Abstract

Between September and November 2020 Lawrence University conducted a geophysical survey in the area immediately northwest of the historic Grignon Mansion. The survey was undertaken to follow up on a previous geophysical survey, conducted in 2018, that identified possible prehistoric structures in that area. A combination of high-resolution magnetic, soil resistivity, and ground penetrating radar surveys were conducted over a 40 meter by 40 meter area in anticipation of better resolving these structures. The survey identified a number of features that appear to support the results of the 2018 survey, thus strengthening the case for the presence of undisturbed prehistoric structures.
