1954 Map of Ophir C-6

About this map

The Kaiyuh Mountains dominate the western half of this sub-arctic landscape, providing a sharp topographic contrast to the low-lying wetlands that spread across the east. Surveyed in the mid-1950s using photogrammetric methods, this map reveals the intricate drainage patterns of the Kateel River Meridian region. The terrain transitions from the elevated ridges of the Kaiyuh range into a dense network of marshes and waterbodies fed by Hather Creek and Mevolt Creek. This area of the Yukon-Koyukuk reflects a wilderness environment shaped by seasonal drainage and glacial legacy, with no roads or trails recorded at the time of the field annotation. The placement of the meridian through this territory emphasizes the systematic effort by the Bureau of Land Management to organize and survey Alaska's interior during the post-war era.
