This is a digital copy of ‘Blind River’, a topographic map printed by the US federal government.
It is part of the Joint Operations Graphic (Air) series at 1:250,000. These topo maps are available throughout the Americas, and they portray the landscape more effectively than United States Geological Survey quads at the same scale. JOGs have the same attention to detail as 1×2 degree quadrangles, but their layer coloring, relief shading, landmarks, and minimal clutter give them superior legibility in the outdoors.
Key details of the printed map:
- edition 1
- published in November 1999 by the National Imagery and Mapping Agency
- air information current through April 5, 1999
- base map compiled in March 1998
- from survey information last dated 1994
This map offers more recent information than the equivalent USGS sheet, which was surveyed 14 years previously, in 1980.
