Hunting a unit you've never set foot in? Glassline compresses 40 hours of e-scouting into a playbook you refine — ranked hunt areas, plays, and packout math, for elk, mule deer or both on one hunt. Built on hunting know-how, not a magic animal-finder.
$39.99/yr — first 500 hunters, rate locked.
Glassline compresses 40 hours of e-scouting into a playbook you refine: hunt areas, camps and plays for elk, mule deer or both, in a Colorado unit you've never set foot in. Then it comes with you, on your phone, signal or not.
$39.99/yr for the first 500 members, locked as long as your subscription is active. Or start free: one hunt, full generation.
Most tools stop when the planning does. Glassline plans the hunt at your desk, then carries the playbook onto the mountain: the night before, the morning of, and the last trip out.
Tell Glassline what you're hunting, your weapon, your style and when you can go. It ranks the units that fit, over the counter or in the draw, and shows the factors behind every rank: season-specific harvest, huntable public land, pressure, access.
Hunt areas ranked Primary, Secondary and Contingency, each with the reasons behind it. Camps your vehicle can reach, with drive times to each area. Plays built on the ground you'll hunt, each with a way in, routing and hike/drive estimates, and packout math. Routed for your fitness, not flagged after.
Glassline maps where each hunt area can be glassed from: road stops your vehicle can reach and hike-in points inside your fitness. Click to show the viewshed and the ground you can see lights up on the map. Then Stand here: drop into 3D at the point, range the far slope, and raise binoculars or a spotter at their true field of view. The viewsheds download with your offline maps.
The LiDAR basemap is bare-earth relief from USGS lidar at 5 m, so benches, cuts, old roadbeds and slide paths show through the canopy. It's free, with slope, aspect and landform layers beside it. For members, the Terrain filter dims everything except the ground you describe: slope, aspect, landform, open or timber, public land, how far from a road your vehicle can drive. Start from a preset (Gentle north-facing timber, Benches off the road, Open parks that warm early, Inside old burns, Openings inside timber) or set your own. No ranking, no pins. Sun and shade shows terrain shadow at any hour of your hunt.
Hybrid LiDAR Know a bench the data missed, or a way in that's on no map? Draw the area, drop the mark or the access point, set the priority, and the plan builds around them. On the phone, tap your own stops and Glassline prices the way in: drive, hike and climb. Rebuild anytime: Glassline redoes its own work and keeps yours.

Hunt mode lays out each day in morning, midday and evening blocks. Wake math works back from legal light, from first light to in position to the trailhead, and sets your alarm. Each night, check in: what you saw, who else was out, the weather.
Boot tracks at the trailhead. Fresh snow overnight. A front inside your dates. Every play carries a decision tree that presents options for what you find. Run shows the plays that fit the light you have left. Relocate sorts camps by the new country each one puts in reach. Conditions and nightly alerts keep snow, drought, fire and the forecast current.
Offline maps and a logistics kit for your hunt: imagery, terrain, the LiDAR basemap, the roads your vehicle can drive, seasonal closures at your dates, every glassing point's viewshed. Build a play at camp, run it, move camp, log what you see. Drive and hike times are estimated on the phone, marked "~", and rechecked when you're back in service.
Every play carries packout math: trips, hours and miles for your party, your pack and your objective, measured from the back of the play. When an animal is down, the Packout block starts a meat-care clock and routes the way out.
A short tour of Glassline in the live app — from describing your hunt to a routed playbook you refine.
Glassline cross-references every integrated dataset and shows its work. In the field, it works from what you report seeing.
Ask GlasslineAsk about the ground, the access, or the packout — every answer cites the datasets it came from.
I've got five days of second rifle, solo, truck camping, decent shape. I'm between two units I've never set foot in — 18 and 28. What should I be weighing?
Here's how they stack up for five days of second rifle, solo, out of a truck camp:
| Unit 18 | Unit 28 | |
|---|---|---|
| Herd (2025 post-hunt) | 3,220 | 2,660 |
| Bull:cow ratio | 29:100 | 26:100 |
| Success rate (recent) | 9–13% | 5–8% |
| Hunter density | 34 days/sq mi | 17 days/sq mi |
| Huntable public land | 64% | 67% |
| Prime burn regrowth | 194,000 ac (East Troublesome) | 14,700 ac (Williams Fork) |
Unit 18 carries the stronger harvest numbers — 9–13% success over the last three seasons against 28's 5–8% — and the East Troublesome burn is a real feed signal: 194,000 acres inside the 4–10-year regrowth window that scores highest for food. The trade is pressure — hunter density runs about twice 28's — and a herd that's slid from 4,145 to 3,220 since 2021.
Unit 28 is quieter country: roughly half the hunter-days per square mile, 50 trailheads against 18's 35, and 67% huntable public. The flag is herd health — the bull:cow ratio dropped from 40 to 26 in one year, and success rates have trended down since 2020.
The trade in one line: the harvest data leans 18; the pressure data leans 28. One note for both — last winter's snowpack came in near 60% of median, so the model has the water weight up and the elevation ceiling higher than a normal year.
You make the call.
Bring years of onX or Gaia pins in as GPX or KML. They shape your plan and no one else's. Send the playbook back out to onX, Gaia or Garmin. onX names, colors and icons survive the round trip.
First and foremost, it saved me many hours in front of the computer and frankly many hours of boots on the ground!
I will absolutely be using it this next year.
Using Glassline has been a unique experience unlike anything that I have used before. Everyone knows about onX, Google Maps, etc., all of which are great, but Glassline takes e-scouting to another level. I have reviewed their information and planning on past units I have hunted, and I have found the data very accurate. I am excited to now try to use the hunt playbook in new units this year!
It is what I have been doing the last few years but using multiple apps, programs, and websites to achieve this. Which included HOURS of staring at aerial photos prior to checking out new areas.
First 500 members. Your rate stays locked as long as your subscription is active. $59.99/yr after.
A fraction of a $499 e-scouting consult, and a rounding error next to a $5,000 guided hunt.
Unlimited hunts — every unit you draw, all four rifle seasons, for one price.

Glassline maps the mountain, never the hunters.
Glassline encodes elk and mule deer know-how — terrain, seasons, tactics, logistics. It never uses real-time animal locations, collar data, or crowdsourced sightings, and it never will. There is no shared hotspot list and no map of where hunters go. Location is used for your own plan — drive times from where you stand and the day's check-in — and your field log shapes your plan and no one else's. We help you plan the hunt. The hunt is still yours.
