The offroad map that works at zero bars.
Dustlark puts legal trails, high-resolution terrain, land ownership, and mud forecasts on your iPhone before you leave pavement, across 11 western states and growing. It knows your rig, reads the road, and keeps your whole convoy on one map with no cell service anywhere in the run.

Why Dustlark exists
Every layer you need, downloaded and yours.
The big map apps went subscription, forced logins, and still leave you stranded when the signal drops. Dustlark is built on public-land data you already paid for as a taxpayer, packaged to live on your phone. No account to make. No location history sold. Core mapping is designed to stay free, including exporting every mile you record.
Optional end-to-end-encrypted sync across your own devices, and an online browse mode through a no-log relay for trip planning, are in development. Offline is not going anywhere. Dustlark works at zero bars today. That will not change.
The Map
The whole backcountry, offline.
- Paint an area, download it. Frame the country you wheel, choose your layers, and pull just those tiles from the statewide archive, so the download is exactly as big as the trip needs. Search, terrain, even Wikipedia keep working with no signal.
- Eleven states, one flagship. Utah, California, Colorado, Idaho, Washington, Oregon, Nevada, Montana, Wyoming, Arizona, and New Mexico are live. Utah runs deepest, with lidar relief, parcel owners, geology, and mud intelligence. Terrain is rolling out state by state.
- Legal routes, not guesses. Official Forest Service motor-vehicle maps plus BLM public-motorized routes, with seasonal closures checked against your trip dates.
- Five looks. Outdoors, crisp 1-meter lidar hillshade, 1890s historic topo, live aerial imagery, and a true-dark Night Stage that flips the whole app after sunset. Lidar hillshade is Utah's today, more states next.
- Land ownership down to the parcel. Owner names are live in Utah, boundaries across every state we cover, so you know whose gate you are looking at.
Plan Like a Guide
One card answers "should we run it?"
- Snap-to-trail routing with live elevation, grade, and a dirt-honest arrival time that slows down for the climbs.
- Fit for your rig. Lidar-measured road width against your mirrors, drop-off exposure, and side-lean, from the Garage profile you set once. Deepest today in Utah, expanding as lidar coverage grows.
- Mud and weather. USDA soil surveys crossed with recent rain and the trip-day forecast: "3 miles on clay-prone soil, give it two dry days." Mud intelligence is deepest in Utah, expanding state by state.
- Auto camps. Set your departure time and Dustlark splits a long route into driving days, then picks each night on legal public land, flat and near a campground. Drag any camp you want moved, and it stays put.
- Drag to reroute. Grab the line and pull it onto the road you meant. Only that leg recalculates. The rest of your route never moves.
From Your Drives
Your phone learns the trail.
- TerrainSense classifies washboard, rock gardens, crawl sections, off-camber lean, and steep pitches from your phone's motion sensors. Any mount, no setup, it self-calibrates as you start driving.
- A live dial on the map shows what the rig is feeling right now, a ring that fills and reddens as it gets rough.
- Your tracks paint themselves by measured roughness, and scrub back through any drive with the map and the graph locked together.
- Plan a route you have driven and the assessment card shows what you actually felt out there, not somebody's guess.
Convoy
Keep the whole group on one map, no bars.
- Pair a Meshtastic radio and every rig shows on your map with name, heading, and how fresh the fix is. The radios relay position rig to rig for miles with no cell service anywhere in the run.
- Navigate to a buddy. Tap a rig for a live distance, bearing, and compass heading. Regroup after a wrong turn or reach a broken-down truck.
- Help beacon. One tap pulses your position and reason ("stuck, need recovery") to every rig on the mesh until you cancel it.
- Message offline. Glove-friendly canned sends and free text hop the mesh like positions. "Airing down at the turnout" reaches everyone.

What Makes It Different
Data nobody else brings to a trail map.
MOAT 01
Terrain sensing
Your own drives measure washboard, crawl, and off-camber. Difficulty you can trust because your phone felt it, not a crowd-sourced star rating.
MOAT 02
1-meter lidar road geometry
Computed road width, cross-slope, and shelf exposure, checked against your rig. "Narrows to 9 feet at mile 6.3." Live in Utah, our lidar flagship.
MOAT 03
Weather to road intelligence
Soil survey plus forecast equals honest mud windows. Know which days that clay two-track is passable. Deepest in Utah today.
MOAT 04
Offline mesh convoy
Your whole group on one map with zero bars, relayed rig to rig over LoRa radio.
The promise Every number on every card cites its source and data date. Where the data is thin, Dustlark says "unknown" instead of a guess dressed up as an answer.
