1952 Map of Holy Cross D-1

About this map

The Innoko River meanders through a vast network of wetlands and shifting channels in this 1952 topographic study. This remote portion of Alaska, mapped by the Army Map Service and published by the U.S. Geological Survey, showcases a complex riparian landscape defined by features like Holikachuk Slough. The geography is primarily a mix of dense low-lying marshes and rising upland terrain, punctuated by survey markers such as VABM Chalet and VABM Innoko. The intricate detail of the river’s oxbows and seasonal water patterns suggests a landscape defined more by hydrological cycles than permanent human infrastructure at the time of the survey. Researchers of Alaska’s interior will find the precise elevation contours and watercourse paths essential for understanding the historical physical geography of the Yukon-Koyukuk region before contemporary ecological changes.
