When this map is printed on an electronic plotter directly from digital files, dimensional 

calibration may vary between electronic plotters and between X and Y directions on the 

same plotter, and paper may change size due to atmospheric conditions; therefore, scale 

and proportions may not be true on plots of this map.

When this map is printed on an electronic plotter directly from digital files, dimensional 

calibration may vary between electronic plotters and between X and Y directions on the 

same plotter, and paper may change size due to atmospheric conditions; therefore, scale 

and proportions may not be true on plots of this map.
