1956 Map of Chandler Lake

Evidence of mid-century exploration appears with the Grandstand Test Well and a Tractor Trail cutting across the northern tundra, contrasting with the ancient geography of the Nunamiut Mtn. The hydrology of the region is mapped in detail, from the namesake Chandler Lake and Little Chandler Lake to the headwaters of the John River flowing south. These features illustrate the transition from the high mountain passes of the Gates of the Arctic Wilderness to the open North Slope borough plains.
