Frequently asked questions

MVUM (Motor Vehicle Use Map)

When MVUM is on, orange lines are USFS MVUM roads and purple lines are USFS MVUM trails. The street basemap may also draw its own national-forest-style roads; those graphics are not MVUM and can remain visible when MVUM is off.

MVUM data in the app is informational only. Always verify the official MVUM for the national forest unit you are visiting (U.S. Forest Service EDW).

With MVUM enabled, route and trail names from USFS (when provided in the source) are drawn along lines at zoom 10 and higher, in addition to the MVUM road and trail lines.

Camping / public land overlays

These fills help you see broad land administration. They are not a camping permit and do not replace on-the-ground rules, closures, or permits.

State trust land is not shown as a map toggle right now. The only source we had integrated was Arizona-only (ASLD); for a nationwide audience that was confusing, so the trip map focuses on BLM and USFS until we can add fair multi-state trust coverage.

• Yellow: BLM surface management areas (national BLM layer).
• Teal: U.S. Forest Service land (national forests). This is the kind of coverage that includes areas such as Tonto National Forest / Roosevelt Lake (national forest, not the same as state trust land).

NFS roads & trails + BLM roads (line map)

This overlay draws inventory-style line geometry, not legal route status on national forest:

• Brown: National Forest System roads (USFS inventory).
• Teal: NFS trails (published transportation layer).
• Orange: BLM motorized / limited-motorized roads from BLM GTLF public display.

Road and trail names on those lines come from USFS/BLM attributes when the source provides them, and typically appear along lines at zoom 10+. MVUM (when enabled) shows legal vehicle use on national forest; the inventory line map is a different dataset and is useful for context only.
