Saturday is the biggest rifle day of the year
This Saturday, Oct 24, two of the biggest rifle openers in the West hit on the same morning. Montana's general deer and elk season opens and runs five full weeks through Nov 29. Colorado's second rifle season opens the same day and runs nine days through Nov 1, with deer and elk both legal and over-the-counter bull elk tags available in a lot of units. If you hunt either state, the days between now and the opener are your whole e-scouting window. In Idaho the clock runs the other direction: any-weapon elk closes Oct 24 in most zones, so this weekend is the last shot at a settled October pattern. Dates change by district and hunt code, and nothing on this page overrides the warden. Confirm your tag, your unit and this year's exact dates on the state planner before you load the truck.
Opener pressure changes everything
The opener does not move the feed. It moves where the animals will tolerate being in daylight. Colorado's second rifle is the most heavily hunted nine days in the state: nonresidents on OTC tags, residents who did not draw a limited tag, and every outfitter client converge on the same units at the same time. Montana's general season runs longer and covers more country, but opening weekend still stacks trucks at every easy trailhead. Educated elk do three things: go nocturnal, move deeper into timber, and leave the country they used before the pressure. That is why e-scouting this week matters more than any other week. The elk are already in the spots the pressure will push them to. The satellite and the layers show you the thick timber, the far benches and the closed roads before you burn a day of the season finding out.
Where the elk are right now
The rut is over and elk are back to routine: feed at night, bed down in timber by morning, hit water somewhere in between. After a month of archery pressure and two weeks of early rifle in Colorado, the herd bulls are not standing in the same meadows they used in September. Look for the thick stuff: north-facing timber near feed, benches above drainages where elk can watch the approach, and pockets more than a mile from the nearest trailhead. In Colorado's OTC units the move is vertical and away. Elk drop off the easy ridges and slide into the dark timber bands the roads do not reach. In Montana the pattern is the same, plus migration math. Any real weather between now and the opener starts pulling elk toward winter range, and the published migration corridors in HuntTrack show exactly which drainages they walk. Cross the corridor lines with the Movebank collar tracks and you are reading routes, not guesses.
Where the mule deer are
Mule deer run a different clock. The rut has not started yet, so opening weekend is a pre-rut hunt. Bucks are feeding hard, building reserves, and checking doe groups on south-facing benches. They are not moving much in daylight, and pressure makes it worse. The setup that wins is feed plus bedding with a view: a bench with fresh green growth, a burn scar or timber cut from the last few years, and a high point to glass it from. Montana's season runs all the way to Nov 29, which means the back half is peak rut hunting. If you can pick your week, the second half is when the big bucks stop being careful. In Colorado's nine-day window you do not get that luxury. Hunt the does. Bucks will check them on the cold mornings at the end of October, and the does are right where the feed and the water meet public land.
Read the access first
Every good spot you find is useless if you cannot legally hunt it. Turn on hunt units, public land and parcels before you mark a single pin. In Colorado, second rifle OTC bull tags are not valid in every unit. Some are OTC, some are limited draw, and the list changes by hunt code, so check your exact unit against the current OTC list before you commit to a trailhead. In Montana, confirm your hunting district, because shoulder seasons and private-land-only tags layer on top of the general dates in some districts. Block Management ground matters too: the parcels and public land layers show you where the FWP access ground actually sits, and the name on the boundary tells you which agency manages it. Keep the public and private boundaries on everywhere, and trust the orange parcel lines for private. That is the standard, in every state.
Stack the layers like the opener depends on it
This is the week to run the full stack. One, migration corridors and collar tracks for where the animals walk. Two, roadkill clusters for the confirmed crossings. Elk and deer get killed where the herd has always crossed, so a creek crossing with repeat kills is a funnel. Three, burn scars and timber harvest for the feed. Three to eight year old burns are the greenest feed in the unit. Four, water and wetlands for the daily loop. Elk drink every day, and the permanent sources near feed are the anchors. Five, slope shading and the satellite basemap for your glassing seat and the walk in. Six, the wind overlay for the setup, remembering thermals slide downhill in the morning and reverse in the evening. Mark three spots where feed, water, corridor and public land overlap, and mark a backup for each. Opening weekend will burn one of them. That is what backups are for.
Opener weekend checklist
Six things to confirm before Saturday, and every one of them is a map layer away.
| The check | What to confirm | Where the map helps |
|---|---|---|
| Your unit and tag | District or hunt code, OTC eligibility in CO, tag type | Hunt units layer plus the units index pages |
| Your dates | MT Oct 24 to Nov 29, CO Oct 24 to Nov 1, district exceptions | Season-aware Open now panel |
| Your access | Public vs private, Block Management, walk-in areas | Public land plus parcels layers |
| Your approach | Closed roads, timber bands, glassing seats, wind | Slope shading plus satellite plus wind overlay |
| Your backup | A second spot for when the first is full | Corridor funnels and far pockets |
| Your offline cache | Tiles cached before you lose signal | Offline mode: viewed tiles cache |
Ten minutes to an opener plan
One, confirm your unit, tag type and exact dates on the state planner. Nothing here overrides the warden. Two, turn on hunt units, public land and parcels and mark where you can actually be. Three, stack corridors, roadkill, burns, water and wind, and mark three spots where it all overlaps on public ground. Four, check the walk in on satellite: roads, closed gates, timber, and a glassing seat for each spot. Five, mark a backup for each spot, because opening weekend is a contact sport. Six, cache the tiles and charge everything. Saturday is four days away. The elk already know where they are going. Now you do too.
