About this map

The Porcupine River carves a winding path through this northern interior landscape, meeting the Salmon Trout River at a sharp bend near Old Rampart. This 1950s survey documents a critical wilderness corridor during the mid-century era of aerial photogrammetry, capturing established locations like Old Camp and the geological formation simply labeled Canyon.

The presence of survey markers such as VABM 988 Red Gate and VABM 1519 Salmon indicates the systematic mapping of the Yukon-Koyukuk region. To the west, the topography is defined by the confluence of Howling Dog Creek and the river, anchored by the landmark Howling Dog Rock. These names reflect the local geography of the Porcupine basin, where seasonal camps and river navigation were the primary markers of human presence.
