Caution: Roads, Trails, and Conditions Change
Before venturing into unfamiliar areas, check with a local ranger or other person knowledgable about current conditions and accessibility.
Different maps covering the same area may show different roads, trails, or features. If in doubt about differences, assume they're all wrong.
Devices can fail in many ways and GPS signals can be blocked by surroundings. Have a compass and paper map as a backup, and know how to use them.
Set reasonable limits and be prepared to turn around if appropriate.
We use these maps ourselves and make reasonable efforts to calibrate them accurately.
The accuracy of these calibrated maps is affected by the accuracy of the maps they were created from.
Variations in projection and scale, and age of the original will affect the accuracy of these maps.
