- LcPd-13, Blackfly Creek: GaK-1867 was collected from an exposed burned soil of black humus and charred spruce wood 3.6 m above the water level. There was weak podsol development under the burned horizon. No cultural materials were associated with the sample, but it is important in dating forest penetration, burning and the establishment of soil horizons in the area. Currently, Winter Lake lies in a forest-tundra transition zone, and Blackfly Creek is within a gallery forest extension. The date is somewhat earlier than expected, making it apparent that tree-line burning in central Mackenzie District is not in phase with the sequence for southern Keewatin District.
