1954 Map of McGrath A-6

About this map

The Tatlawiksuk River winds through this interior landscape, which was mapped by the Geological Survey using aerial photography from the mid-1950s. The terrain is defined by a significant contrast between the high, un-wooded ridges and the expansive wet lowlands that dominate the western half of the quadrangle. In the eastern portion, the river creates complex drainage patterns near a curious landmark labeled Shifting Sand, an indication of the active alluvial processes at work in this subarctic environment. The lack of established roads or trails during this period highlights the remote character of the region. As part of the Seward Meridian, the land lines here were predetermined by the Bureau of Land Management but remained largely unsurveyed and unmarked on the ground at the time of this survey's field annotation.
