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 useless 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 easy methods to plan new routes which are environment friendly to journey, secure, and quick is a talent that’s solely mastered after you’ve spent a good period of time roaming off-trail and discovered the form of terrain and vegetation to keep away from.
Three Rules
There are three ideas of wilderness navigation that you really want to bear in mind when planning wilderness routes: effectivity, security, and velocity.
Effectivity
Mountaineering cross-country is significantly harder than mountaineering on cleared and well-defined trails. One of many first stuff you’ll discover is that the bottom is affected by rock and natural particles that you want to hike over or round. Tall grass, bushes, bushes, bogs, and boulders might block your manner. The hills will probably be steeper than you’re used to encountering on trails and your regular mountaineering tempo will probably be a lot slower.
Cautious examine of a topographic map will reveal routes which are simpler to stroll than others, with gentler gradients and detours round troublesome obstacles. For instance, cliffs are greatest hiked round moderately than tackled head-on and the edges of streams are greatest prevented as a result of they’re typically crammed 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 harm whenever you step off trails and head out into open nation. It’s additionally greatest to keep away from steep ravines as they’re typically 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 wish to make real-time detours round harmful terrain which you can’t anticipate based mostly on the data offered by maps or different planning assets.
Velocity
Regardless of the issue of wilderness journey, there are land options which you can comply with that make cross-country journey sooner and simpler. For instance, mountaineering above treeline is usually sooner than beneath it, offered you might have good climate. Mountaineering alongside gravel river bars can be a lot sooner since there is no such thing as a impeding vegetation. However there are additionally many varieties of terrain that may considerably gradual you down as a result of they’re boulder or vegetation traps resembling steep hillsides or ravines.
A Route Planning Instance
Studying easy methods to plan a route that’s vitality environment friendly, secure, and quick to hike is the essence of wilderness navigation. Let’s have a look at an instance for example the method.
Assume we’re standing on prime of closely forested Mt Martha (on the map above) and wish 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 important thought, since that direct route isn’t energy-efficient, secure, 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 form of drainage, earlier than climbing uphill to The Humps.
- The descent down the east aspect of Mt Martha is 774′ in 0.4 mile, which is kind of precipitous, and there’s an excellent likelihood that it’s coated with boulders and bushes which have eroded or fallen over and been swept down the hillside. Choosing your manner by means of that crap will take an infinite quantity of vitality, you possibly can simply twist an ankle or break a leg within the course of, and it’d most likely be fairly gradual going. Crossing the drainage (the “V” on the backside of the valley) and climbing out of it’s also more likely to be a horrendous slog since all the 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 mountaineering 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. Aspect-hilling will be exhausting as a result of one leg is at all times larger 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 ft to a flat space known as a saddle earlier than climbing simply 108′ to the unnamed peak. The saddle is most likely coated with bushes, together with some blown over bushes on the bottom, however simple to cross as a result of there’s so little gradient.
- The second leg regularly drops 550′ ft down the ridgeline to The Humps over the course of 0.8 miles. I might count on spruce above 3000′ then turning to open hardwoods that are sooner to hike by means of.
Whereas the blue route requires about 50% much less elevation acquire than the crimson route, the most important vitality financial savings between the 2 is avoiding the particles beneath Mt Martha’s japanese slope that you simply’d should hike by means of. That may very well be a whole nightmare by way of effort, security, and velocity. There’s none of that on the blue route, although it’s 0.2 miles longer, making it a greater off path route.
Wilderness Route Planning
The essence of Wilderness Navigation is studying easy methods to make selections about the most effective cross-country routes throughout unfamiliar terrain by way of vitality expenditure, security, and velocity. Whereas studying easy methods to comply with a bearing utilizing a compass, GPS, or smartphone app is a crucial prerequisite to following a wilderness route, crucial route planning talent to develop is studying easy methods to learn a topographic map and making inferences in regards to the panorama it depicts.
Whereas there’s an abundance of wonderful GPS route planning instruments out there, 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 alternate options hastens the training course of. When you possibly can have a look at a map and rapidly determine the most effective off-trail path to take, you’ll have internalized the three ideas of wilderness navigation route planning: effectivity, security, and velocity.
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!
