1987 Map of Chandler Lake D-5

About this map

The Ayiyak River meanders across this northern landscape, forming the central geographic spine of this Arctic interior survey. This 1980s data represents a time when the Bureau of Land Management was still formalizing land lines across vast unsurveyed tracts of the North Slope. The drainage patterns are intricate, with Mammoth Creek flowing into the main river from the south while East Fork Ninuluk Creek and South Fork Ninuluk Creek dominate the northwestern quadrant. A notable topographic landmark is the Hatbox Mesa in the southeast, a distinct landform rising above the surrounding river valleys. The map also records early survey markers like ST 60190 and ST 60191, which provided critical reference points for mapping this terrain before modern GPS technology. The lack of any roads or buildings emphasizes the wilderness character of the region during this era.
