Results of a portion of the magnetic survey revealing a number of discrete clusters of anomalies. The relatively high amplitude anomalies (appearing in color) are thought to be associated with Late Archaic hearths. In several cases, hearth features were exposd on the surface, providing immediate verification of the origins of anomalies. A number of smaller, low-amplitude positive anomalies (appearing as black) can be seen in rough clusters. These may be caused by induced-field phenomena associated with features such as storage pits or postmolds. Around the most northerly of the suspected hearths there appears a very faint oval about 8m in diameter. This may be caused by an architectural feature - perhaps a lodge or tent - which had a hearth in its center. Another less distinct 'ring' may appear around the suspected hearth at N25/E22. Electrical resistance survey was conducted over the 20-x-20m square outlined in yellow.
