In order to maximize the our limited resources, to locate additional
possible archaeological materials and to learn new methods for archaeological
remote sensing, in December 2000 a magnetometer survey of parts of
the campus was carried out by a team consisting of faculty and students
using a rented hand-held Cesium Magnetometer. Magnetometers
are capable of detecting very slight anomalies in the earth's magnetic
field which are sometimes caused by ferrous metal (iron or steel)
or concentrations of ceramic materials such as bricks.
Geologist, Dr. Criss Capps of ASU's Chemistry & Physics
Department, checks and calibrates the cesium magnetometer before
beginning to collect data for analysis. Using the magnetometer the
team was able to locate several promising areas where further subsurface
study is justified. Two of these areas have been excavated
resulting in the exposure of the foundation of the Guardhouse bell
tower and the Arsenal well in the President's Garden.
