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 depends on the maps they were created from, and may be affected by variations in projection, scale, and age of the original. Use common sense, be aware of your surroundings, and always have other methods to determine your position and plan your route.
