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.

These downloads are psvz file bundles containing one or more album files, photos, map tiles and any other required files. Psvz files may contain gpx, kml, kmz, or okm files that could be converted or directly loaded on GPS devices.
  • In EcoRamble, tap the folder icon.
  • In Photo Sieve®, load with the "Files/Load Album" menu.
After selecting the psvz file, everything will be unpacked and you can select a psiv album file. If there's more than one album file, start with the album having the same name as the psvz file.
