2014 Map of Bologna Basin
USGS Topo · Published 2014About this map
The North Fork John Day River meanders through the central portion of this landscape, carving a significant path through the southern reaches of the Umatilla National Forest. This 2014 survey documents a region defined by complex drainage systems and high-elevation landmarks such as Negro Knob and Thorn Spring Butte. The map reveals a reliance on isolated water sources, naming several dispersed springs including Putnam Spring, Bologna Spring, and Tommy Cork Spring, which likely served as vital points for livestock or local forestry operations.
