Spotting a Designated Route on a Medicine Bow Map
A line on a Medicine Bow map can look like an invitation to ride, but it may show a road, a hiking trail, a closed route, or a route with seasonal limits. That uncertainty is frustrating when you’re planning a ride near Laramie or the Snowy Range. This guide explains how to identify designated motorized routes, check their conditions, and avoid relying on a map line alone.
Start with the map that answers the access question
Use the Motor Vehicle Use Map for legal route designations
For National Forest land, start with the Forest Service’s Motor Vehicle Use Map, usually called an MVUM. It identifies routes designated for motor vehicle use and can show restrictions such as vehicle type, season, or width. A general recreation map may be easier to read, but it may include roads or trails that aren’t open to the machine you plan to ride.
The key distinction is between a route that appears on a map and one that is designated for your kind of motorized travel. A thin line on a topographic map might simply represent a path or old road. The MVUM’s legend and notes tell you how to interpret its specific line styles and symbols. Don’t assume a route is open just because it is drawn clearly or appears to connect two popular riding areas.
The Medicine Bow National Forest covers a large area, and route access can vary by location and season. When you download a map, check that it applies to the part of the forest you intend to ride. If you’re comparing maps, make sure they show the same area and that you understand which one is intended to show motor vehicle designations. [Medicine Bow Designated Routes Only] explains why staying on designated routes matters.
Read the legend before tracing a route
It’s tempting to zoom in, spot a promising line, and start planning around it. Take a moment to read the legend first. The map’s line patterns, colors, route numbers, and labels are only meaningful when you know what that particular map uses them to represent. A dashed line, for example, does not mean the same thing on every map.
Look for the map’s notes about designated roads and trails, allowed vehicle classes, seasonal dates, and any route-specific limits. If the map separates roads from trails, don’t assume an ATV or UTV is allowed on both. A trail may have a width restriction, while a road may be open to a different range of vehicles. [Wyoming's 50-Inch Trail Limit] is useful background if you’re trying to determine whether a wider side-by-side may be excluded from a particular trail.
Check the map’s title, coverage area, legend, and publication information before relying on it. If you’ve printed a map, confirm that the legend and fine-print notes are legible. If a detail is too small to read, zoom in or consult another official copy rather than guessing from the line itself.
Trace the route and check every restriction
Follow the route from beginning to end
Once you’ve identified a line that the legend describes as a designated motorized route, trace the full route—not just the part that looks appealing. Find its starting point, its connections, and its endpoint. A route can end before it reaches the destination you had in mind, or it may connect to another route with different access rules.
Pay close attention at intersections. Two lines crossing on a map don’t necessarily mean the routes connect in a way you can ride. One may pass over another, stop short, or continue as a route with a separate designation. Check for route numbers, junction labels, and other details that clarify which line you’re following. If the map is dense, note the relevant junctions before setting out so you aren’t trying to interpret a cluttered screen while riding.
For a trip that combines forest roads and trails, verify each segment individually. A route can be open while the next segment is closed, limited to another vehicle type, or subject to a seasonal restriction. [Wyoming's Enrolled Roads and Trails] offers broader context on how route access is organized across Wyoming, but you still need to check the specific land manager’s map for the area you plan to visit.
Look for machine, width, and seasonal limits
A route designation is not a blanket permission for every vehicle. Look for restrictions that apply to your ATV or UTV, including any posted width limit or vehicle class. This is especially important if you’re riding a side-by-side: a narrow trail suitable for a smaller machine may not be open to a wider model.
Seasonal access deserves equal attention. A route might be open only during a stated period, or its status might depend on conditions and temporary closures. Don’t treat a date range as a promise that the route will be passable. Snow, mud, fire restrictions, wildlife protections, or other management decisions can affect access. Confirm current local conditions before you leave, particularly early or late in the riding season.
| What to check | What it tells you | What to do if it is unclear |
|---|---|---|
| Route line and map legend | Whether the line represents a designated motorized road or trail | Compare the line with the legend; don’t infer access from appearance |
| Route number or label | Which segment you are tracing through junctions | Record the number and check each connected segment |
| Vehicle or width restriction | Whether your ATV or UTV fits the designation | Check your machine’s width and the route notes |
| Seasonal dates | When the map indicates the route is open | Confirm whether temporary closures or conditions affect access |
| Map coverage and notes | Which area and rules the map applies to | Use the map for the correct forest area and read its fine print |
| Signs or closures on the ground | Whether access has changed or is restricted at the route | Follow posted restrictions and check with the managing office if needed |
If the map and a posted sign appear to disagree, don’t assume the map gives you permission to continue. A sign may reflect a temporary closure or a more specific restriction. Stop before entering the questionable segment, note where you are, and seek clarification from the responsible land manager. [When a Map and a Sign Disagree] covers this situation in more detail.
Confirm what you see on the ground
Treat signs as part of route identification
At the trailhead or route junction, look for signs that identify the route, state a restriction, or indicate that it is closed. A sign can help confirm you are at the junction you intended to reach. It can also alert you to a limitation that is easy to miss while studying a map at home.
Don’t treat the absence of a sign as proof that every route nearby is open. Signs may be located at key access points rather than at every turn, and a junction can be easy to misread. Keep your map available as you navigate, and compare your location with the route you traced in advance. If the terrain or junction doesn’t match your map, pause and reassess instead of choosing the most inviting-looking track.
If an official map marks a segment open but a closure sign is posted at the entrance, obey the sign. The safest response is to avoid the segment until you’ve confirmed its status. [When a Sign on the Ground Says Closed] and [What a Wyoming Warden Checks at a Trailhead] provide related guidance on closures and trailhead checks.
Use digital maps as a planning aid, not a substitute for the official designation
Digital tools can make route planning easier. For example, onX Offroad can help you review terrain, save a planned route, and keep useful map information available while you travel. That can be handy when you’re comparing a possible loop near the Snowy Range with your official Forest Service map or preparing for limited cell service.
Still, use an official MVUM to confirm the motorized designation and its restrictions. A digital map layer may help you understand where a route runs, but it should not replace checking the map’s legend, seasonal limits, and route-specific notes. Before the trip, compare the route you saved in onX Offroad with the official map, especially where your plan crosses a junction or changes from road to trail.
Download the information you need before leaving reliable service and carry a usable backup. A phone can lose signal, run out of power, or become difficult to read in bright sunlight. A paper map or a second offline map source can help you stay oriented if your primary device fails. [Wyoming Trail Maps and MVUMs] explains how these map types fit into route planning.
Build a reliable route plan before you ride
Make a simple route checklist
Before leaving, write down the route number or name for each segment, its junctions, and any access limits that apply to your machine. Note where the route starts and ends, and identify a suitable turnaround point if a closure or confusing junction prevents you from continuing. That small bit of preparation can prevent the stressful moment of discovering that your intended loop depends on an unverified connection.
A practical check can look like this:
- Identify the correct MVUM for the area you plan to ride.
- Read its legend and confirm which symbols show designated motorized routes.
- Trace your entire route, including every connecting segment.
- Check vehicle class, width restrictions, seasonal dates, and map notes.
- Compare your plan with any digital map you’ll use offline.
- Check for local closure notices before departure.
- At the trailhead, match the signs and junctions to your planned route.
- Stop and reassess if a posted sign or the terrain conflicts with your plan.
A route plan should also account for time and changing conditions. Mountain weather can shift quickly, and a route that is straightforward on a map may take longer than expected because of rough ground, mud, snow, or stops at junctions. Build in enough flexibility to turn around rather than pressing ahead because you’re trying to complete a planned loop.
Know when to ask for clarification
Some map questions can’t be answered confidently from a screenshot or a line on a phone. If the legend is unclear, route designations appear inconsistent, or a junction has a sign you don’t understand, contact the appropriate Forest Service office before riding that segment. Give them the route number or location and describe the machine you plan to use. Asking about the exact segment is more useful than asking whether a broad area is “open.”
It’s also worth asking when your machine is close to a listed width limit or when the route appears to connect with land managed by another agency. A designation on one side of a boundary doesn’t automatically settle access on the other side. Keep your route on clearly designated ground unless you’ve confirmed the next segment’s rules.
Finally, avoid treating older screenshots, saved routes, or a friend’s past experience as proof of current access. A route may have been open when someone last rode it and later become subject to a closure or restriction. For additional guidance on staying on mapped routes, see [Riding a Road Instead of a Trail] and [Wyoming Trail Closures to Check First]. A few minutes spent checking the map, the restrictions, and the signs is far less frustrating than discovering the problem after you’ve ridden miles into the forest.
