Wilderness navigation requires planning routes throughout terrain that doesn’t have pre-defined trails or roads to comply with. Whereas following a route utilizing a map and compass, GPS, map-to-terrain affiliation or simply lifeless reckoning is required, these instruments and methods don’t offer you the talents to plan good cross-country routes. Half artwork and half expertise, studying the best way to plan new routes which are environment friendly to journey, protected, and quick is a ability that’s solely mastered after you’ve spent a good period of time roaming off-trail and realized the sort of terrain and vegetation to keep away from.
Three Rules
There are three rules of wilderness navigation that you really want to bear in mind when planning wilderness routes: effectivity, security, and pace.
Effectivity
Climbing cross-country is significantly harder than mountain climbing on cleared and well-defined trails. One of many first belongings you’ll discover is that the bottom is affected by rock and natural particles that you’ll want to hike over or round. Tall grass, bushes, bushes, bogs, and boulders could block your method. The hills will likely be steeper than you’re used to encountering on trails and your regular mountain climbing tempo will likely be a lot slower.
Cautious research of a topographic map will reveal routes which are simpler to stroll than others, with gentler gradients and detours round tough obstacles. For instance, cliffs are finest hiked round moderately than tackled head-on and the perimeters of streams are finest prevented as a result of they’re usually stuffed with dense vegetation and flood particles.
Security
The necessity to hike throughout avalanche terrain, scree-covered slopes, and river crossings all improve the hazard of getting damage whenever you step off trails and head out into open nation. It’s additionally finest to keep away from steep ravines as they’re usually catchments for ankle-busting boulders, fallen bushes, and vegetation. Whereas many of those hazards will be anticipated by studying to research topographic maps, you’ll additionally need to make real-time detours round harmful terrain you could’t anticipate primarily based on the data supplied by maps or different planning assets.
Velocity
Regardless of the issue of wilderness journey, there are land options you could comply with that make cross-country journey quicker and simpler. For instance, mountain climbing above treeline is commonly quicker than beneath it, supplied you’ve got good climate. Climbing alongside gravel river bars can be a lot quicker since there isn’t any impeding vegetation. However there are additionally many varieties of terrain that can considerably sluggish you down as a result of they’re boulder or vegetation traps comparable to steep hillsides or ravines.
A Route Planning Instance
Studying the best way to plan a route that’s power environment friendly, protected, and quick to hike is the essence of wilderness navigation. Let’s take a look at an instance as an example the method.
Assume we’re standing on prime of closely forested Mt Martha (on the map above) and need to hike over to a characteristic that’s 9/10 of a mile away, because the crow flies, known as The Humps. When you’ve got a GPS, it’s completely conceivable that you simply’d plug within the lat/lon location of The Humps, plot the shortest path to it, and set off to comply with it. However that wouldn’t be such an ideal thought, since that direct route isn’t energy-efficient, protected, or quick to hike.
Discover that the route descends very steeply down the face of Mt Martha right into a steep valley, earlier than crossing what is probably going some type of drainage, earlier than climbing uphill to The Humps.
- The descent down the east facet of Mt Martha is 774′ in 0.4 mile, which is sort of precipitous, and there’s an excellent likelihood that it’s lined with boulders and bushes which have eroded or fallen over and been swept down the hillside. Choosing your method by means of that crap will take an unlimited quantity of power, you possibly can simply twist an ankle or break a leg within the course of, and it’d most likely be fairly sluggish going. Crossing the drainage (the “V” on the backside of the valley) and climbing out of additionally it is prone to be a horrendous slog since the entire particles from the slopes overhead will gather at that time.
- Whereas the climb from the drainage to the excessive level of The Humps is barely 250′ over 0.5 miles, you’d be side-hilling, or mountain climbing up the slope at an angle. You are able to do it, it’s often extra environment friendly to hike perpendicular to the contour line to distribute the work equally between your legs. Facet-hilling will be exhausting as a result of one leg is all the time greater than the opposite and doing extra work.
A Higher Route
The blue route (above) from Mt Martha to The Humps will be damaged down into two legs: a 0.4 mile leg which crosses the saddle to the unnamed peak south of Mt Martha, and the second leg, an 0.8 stroll down the ridge to The Humps.
- The primary leg drops 164 toes to a flat space known as a saddle earlier than climbing simply 108′ to the unnamed peak. The saddle is most likely lined with bushes, together with some blown over bushes on the bottom, however straightforward to cross as a result of there’s so little gradient.
- The second leg progressively drops 550′ toes down the ridgeline to The Humps over the course of 0.8 miles. I’d count on spruce above 3000′ then turning to open hardwoods that are quicker to hike by means of.
Whereas the blue route requires about 50% much less elevation acquire than the crimson route, the most important power financial savings between the 2 is avoiding the particles beneath Mt Martha’s jap slope that you simply’d should hike by means of. That could possibly be an entire nightmare when it comes to effort, security, and pace. There’s none of that on the blue route, regardless that it’s 0.2 miles longer, making it a greater off path route.
Wilderness Route Planning
The essence of Wilderness Navigation is studying the best way to make selections about the very best cross-country routes throughout unfamiliar terrain when it comes to power expenditure, security, and pace. Whereas studying the best way to comply with a bearing utilizing a compass, GPS, or smartphone app is a vital prerequisite to following a wilderness route, a very powerful route planning ability to develop is studying the best way to learn a topographic map and making inferences concerning the panorama it depicts.
Whereas there’s an abundance of wonderful GPS route planning instruments accessible, the one solution to study the implications of various landforms proven on maps is to get out and hike off-trail as a lot as you possibly can, ideally with a companion, as a result of discussing completely different route options hastens the educational course of. When you possibly can take a look at a map and shortly determine the very best off-trail path to take, you’ll have internalized the three rules of wilderness navigation route planning: effectivity, security, and pace.
Think about, with the ability to hike anyplace your two legs can take you. That’s whenever you’ll expertise the true freedom of the hills!
