Hiking Trail Directory rates this route expert from the available distance and elevation measurements. That rating is useful for comparing routes in the directory, but it does not establish technical terrain, exposure, path condition or the skills required on the day. The start and finish differ on this point-to-point route; arrange the return journey before setting out.
The source data records route tags for mountain and membership of the rwn network. These attributes describe the route record as a whole; they do not prove that every section has the same surface, signage or feature.
The directory season field highlights june to october. This is planning metadata, not a live statement about snow, closures or trail condition. Butte is the nearest linked city in the directory, approximately 25.8 km away in a straight line.
The map is derived from OpenStreetMap and contains 75 geometry points. Elevation values were sampled from terrarium-z11. The traceable source record is 8106945. Open-data records can lag behind reroutes and closures, so compare the source, official notices and the forecast before travelling.
Plan around this route’s details
- Start, finish and return
- The recorded 41.3 km line has different endpoints. Confirm travel from the finish before setting out; that return journey is additional to the mapped route.
- Climbing in context
- The recorded ascent averages approximately 20 m of climbing per kilometre across the whole route. This is climbing density, not trail gradient: climbs and flatter sections may be unevenly distributed. Recorded descent totals 691 m and also needs time in your plan.
- What needs a separate check
- This record does not establish surface, dog access, wheelchair access. Check any of these that affect your group. Current closures, access arrangements and transport are not verified by the route line.

Your walking-time scenario
Adjust the example pace and allowances to explore your own plan. This calculator uses your inputs, so it may differ from the directory’s headline estimate.
Calculated walking time including your allowances
12 hr 14 min
619 min for distance + 84 min for ascent + 30 min allowance.
This is an aggregate calculation for a long outing. It does not plan overnight stages, accommodation or recovery.
Formula: distance ÷ pace × 60 + ascent ÷ 100 × climbing allowance + stops. Travel to and from the route is additional. Terrain, descent, weather and navigation are not modelled. These results do not establish route suitability. Read the time-planning guide.
Recorded route measurements
The start and finish differ on this point-to-point route; arrange the return journey before setting out. The mapped distance is 41.3 km (25.7 mi), with 840 m (2,756 ft) of recorded ascent, with 691 m (2,267 ft) of recorded descent. The sampled elevation profile records a maximum grade of about 13%; this is a calculated value and may smooth short, steeper sections. The profile reaches 2,077 m (6,814 ft) from a recorded low of 1,439 m (4,721 ft).

Tips from the trail
- Open the linked source record before departure to check whether the mapped relation has changed.
- Save the route line offline; a map download is useful regardless of expected phone coverage.
- Use 2 days as estimated moving time, then add your own allowance for stops, conditions and daylight.
- Confirm return transport and its operating hours before starting this point-to-point route.
- Carry enough food and water for the full route; water availability is not established by the map data.
- Follow local access rules and leave no litter or food waste behind.
Warnings
- This guide does not contain live information about closures, hazards, snow, flooding or path condition.
- The route reaches a recorded elevation of 2,077 m (6,814 ft); obtain a location-specific mountain forecast and check seasonal access.
- The finish is separate from the start, so a missed transport connection can materially extend the outing.
Safety
Emergency services in United States can be reached on 911. Share your route and expected return time with someone before leaving. The directory has no verified coverage map or live trail-status feed, so do not rely on phone reception or this page alone. Turn around when conditions, access or your remaining time no longer match the plan.
What to bring
- Footwear suited to the current surface and conditions
- Weather layers appropriate to the local forecast
- Offline route map and a backup navigation method
- Food and water for the planned time plus a reserve
- Charged phone and a small first-aid kit
- Head torch and an extra warm layer for a longer outing
- Trekking poles if you normally use them on sustained ascent and descent
Photography
