1997 RCAHMS Aerial Survey

The period from November 1996 to October 1997 has seen wide-ranging aerial reconnaissance by the RCAHMS. During 106 hours in the air a total of 674 sites were recorded, a considerable reduction on the previous year's total of 1159. The weather of 1996-7 was very mixed, and the warm and dry conditions of July to September were not timed to benefit the formation of cropmarks.
