At the request of Alberta Forest service (Superintendent, Slave Lake Forest) via Public Lands (B. Hudson) the Aggregate Inventory, Alberta Research Council (Fox and Richardson) conducted field work during the days of October 31st and November 1st, 1984, in the Red Earth area of Alberta.
A review of available data - soil maps, water well logs, Alberta transportation information, aerial photo interpretation - quickly indicated that the possibility of finding good aggregate deposits, other than sand, in the area was limited. Consequently a wider geographical area was searched. The presence of 0.5m + of snow cover, with unfrozen ground and the large geographical area indicated the use of helicopter travel.
