Colorado high country at first light.
AI e-scouting · Colorado elk

It does the research.
You make the call.

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. Built on elk-hunting know-how, not a magic elk-finder.

Leftover list is up. I can hunt 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 18Unit 28
Herd (2025 post-hunt)3,2202,660
Bull:cow ratio29:10026:100
Success rate (recent)9–13%5–8%
Hunter density34 days/sq mi17 days/sq mi
Huntable public land64%67%
Prime burn regrowth194,000 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.

To the field

Take it anywhere.

Glassline is the planning layer, not another map to manage. Build the plan here, run it in the apps already on your phone.

In: your waypoints

Years of pins in onX or Gaia? Bring them. Glassline imports GPX and KML, and the ground you already know shapes the plan.

Out: the field kit

Every plan exports as GPX and KML — the points you kept and the routes between them — into onX, Gaia, or Garmin.

Glassline runs in your browser — built for desktop e-scouting, responsive on your phone. Native apps are coming.

What hunters are saying
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.

Super user-friendly, and I can't wait to use it out in the field. As someone who sometimes hunts solo, I've been looking for something like this.

We are fair chase hunters

Glassline maps the mountain, never the hunters.

Glassline encodes elk-hunting 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. We help you plan the hunt. The hunt is still yours.
