Where the layers live

Open the side panel (the green tab on the right edge of the map) to find every toggle. Layers are grouped roughly by purpose: official data first, community next, then weather and tools.

Public lands

Public lands overlay Pro

Color-coded polygons for every federal and tribal land manager — BLM, USFS, NPS, Fish & Wildlife, DOD, BIA, BOR, plus state lands. Source: USGS PAD-US (Protected Areas Database). Updated yearly.

Wilderness areas Pro

Designated wilderness boundaries from the National Wilderness Preservation System. Useful because wilderness has stricter rules than regular USFS or BLM (no motorized access, no mountain bikes, etc.).

Government campgrounds (free)

Recreation.gov + NPS official campgrounds. Tap a pin for facility type, agency, road access, and a link to make a reservation if available.

Roads and trails

USFS Forest Service roads Pro

Forest road network from the USFS authoritative data. Typically the named/numbered roads inside national forests.

MVUM (Motor Vehicle Use Map) Pro

The legal motorized routes inside national forests, broken down by vehicle class and seasonal restrictions. This is the layer you want before you point a 4x4 down a forest road — it tells you what's actually open to you.

OHV areas Pro

BLM-designated off-highway vehicle areas plus the BLM ground transportation linear features (roads, trails, primitive routes). Where you can legally ride.

Trails Pro

USFS and NPS trail networks (non-motorized). Hiking, horse, and cross-country ski trails.

Fire and safety

Active fire perimeters (free)

Live wildfire perimeters from NIFC (National Interagency Fire Center). Refreshes every 30 minutes. The "current" feed only shows fires with recent activity, so old perimeters from prior years drop off automatically.

Hunting

State hunting units Pro

Game management areas, broken down by state and species (elk, deer, etc.). Sourced state-by-state from each state's wildlife agency. Tap a unit to see the unit number, species, and any extra metadata the state provides.

Cell coverage Pro

Carrier coverage maps overlaid on the terrain. Switch between T-Mobile, AT&T, and Verizon. Source: CellMapper. Rough but useful — knowing roughly where signal returns is the difference between a relaxed lunch break and panic-walking around looking for bars.

Topo and elevation

Topo overlay Pro

Contour lines and shaded relief generated from Terrarium elevation tiles. Helpful when the base map's relief shading isn't enough to read steep terrain.

Community layers

Places (free)

Every public place saved by the community — campsites, water, fuel, viewpoints, trailheads. Filter by attributes, place type, and cell signal in the side panel. See Saving places for adding your own.

Note pins Pro

Your own private text + photo notes. They aren't visible to anyone else.

Tribe notices on map (free, members only)

Toggleable overlay for any tribe you're a member of. Off by default. See Tribes & chapters.

OSM POI layers (free)

Pre-built community-maintained pins for camp sites, gas stations, water taps, Walmart parking. Pulled from OpenStreetMap and rebuilt weekly. Each one has its own zoom floor — you'll see Walmart pins at a wide zoom, but fuel/water need you to be zoomed in further.

Weather + time tools

Weather widget Pro

Current temperature, wind, humidity, pressure, and a short forecast for wherever the map is centred. Updates every time you re-centre.

Sun & moon Pro

Sunrise, sunset, golden hour, blue hour, and moon phase. Useful for photographers and people planning to set up camp before dark.

Navigation tools

Digital compass + inclinometer Pro

True/magnetic bearing using your device's compass, plus an inclinometer that reads your phone's tilt. Magnetic declination is corrected via NOAA — accurate within a degree across the lower 48.

Real Compass Pro

A draggable baseplate-style orienteering compass that overlays the map. Rotate the bezel, line up north, and read the bearing to anywhere on the map. Includes a 1 km grid and toggle between magnetic and true north.

Search

Place + GPS coordinate search (free)

The search bar at the top of the map handles two things:

  • Place names — towns, parks, forests, points of interest. Powered by Photon (OpenStreetMap-based).
  • GPS coordinates — paste any common format and the map flies there. Decimal (40.7, -74.0), DMS (40°42'N 74°0'W), cardinal prefixes/suffixes (N40.7 W74.0). It's parsed locally — no network needed.

Layer hygiene

Don't turn everything on. Layers are stackable and the map will happily render eight overlays at once, but it gets hard to read fast. Toggle off what you're not using right now — your eyes and your phone's GPU will thank you.
