How to Create Your Own High Route

A Line Across the Sky

Over the last year, I have developed a reputation for “high routes” – off trail, non-technical traverses in the alpine. High Routes exist in a broad space between mountaineering, backpacking, and trail running. These trips inspire me so much because they blend many different skills – route finding, endurance, scrambling, snow travel – into a cohesive experience (you’ll notice I emphasize the entirety of the experience). I have begun to get questions from people about high routes: how do you come up with these ideas? How do you plan them? How do you determine if they are feasible? So I decided to write a post about the process of creating a high route…

The Vision

High Routes begin with a simple vision – to stay as high possible while remaining non technical. Obviously, “technical” can have different definitions but the main takeaway is that the movement should be fluid, allowing one to cover as much alpine terrain as possible and not be weighed down by technical pitches and cumbersome gear. If there was one word to describe the High Route experience, I believe it would be purity: we move in a way that is pure across a landscape that is pure.

The Area

High Routes are all about aesthetics. When you choose an area for a high route, you are selecting a canvas for your artistic creation. There can be many sources of inspiration for a high route. With the Cascade High Route, the greater concept for a high route from Snoqualmie Pass to Canada dictated some of the terrain choices, as I was simply trying to link high routes near the Cascade Crest. With the Dakobed Range Circumnavigation, my obsession with the Napeequa River Valley drove me to scheme a way of exploring yet another magical part of the virgin valley. With the Triple Rainbow High Route, I purposefully sought out an area of the Cascades that feel overlooked and almost mysterious. The Alpine Lakes Crest Traverse was borne out of a winter of staring at these peaks while skiing near Snoqualmie Pass, wondering what secrets they held. This is where you can express who you are, your signature style. Maybe it is a remote serrated granite ridge that draws your eye, or a reclusive pocket glacier, or a pristine alpine lake. What areas are special to you? What is the experience that you seek? Let yourself be inspired.

Access

As much as people like to think so, I don’t actually enjoy bushwhacking. Okay, maybe I like a little wet brush for breakfast in the morning… In the Cascades, one of the biggest challenges to high routes in access. Ideally, you want to use trails to access and leave the alpine. Oftentimes, there are trails crossing passes that we can use to access an alpine ridgeline. Loops are nice, but sometimes car shuttles are needed to execute the purest traverses, such as the Extended Ptarmigan Traverse. If you cannot use trails to approach or descend, look at satellite imagery for boulder fields, moderate timbered ridges, or snow fingers (depending on the season). Avoid avalanche paths and the accompanying slide alder at all costs, which brings me to the subject of terrain selection…

Terrain Selection

Terrain and route selection is obviously the nitty gritty details of a high route. In general, look for high elevation benches, snowfields, and glaciers to traverse. Don’t be afraid to lose elevation and quickly regain it to avoid cliff bands and difficult sidehilling. When it comes to the local area, you should leverage your local knowledge about common terrain features. For example, in the Eastern Cascades, north and east sides of peaks tend to be steeper, rockier, and more unstable because they were more recently glaciated and less soil has accumulated since glaciation. In the Brooks Range of Northern Alaska, flat terrain at the valley bottoms is incredibly boggy and tiring to move through, while terrain just a hundred feet above on the sides of the valley can be easy travel.

  • Ridges: True ridges are usually very slow for travel and have lots of unnecessary ups and downs and possibly technical sections. Usually avoid if you want to cover a good distance. However, sometimes the best rock is found on ridge tops.
  • Glacial Benches: In ranges like the Cascades, there are frequently “hanging valleys” where an older deceased glacier carved away a steeper lower valley, leaving a bench beneath the upper glacier. These can frequently provide aesthetic, brush free, relatively flat travel above steep, brush filled basins. Getting up out of the lower basins into the hanging valleys can be tricky, but there are usually weaknesses.
You can see the glacial benches that wrap around this entire valley.
  • Sidehills: Sidehilling is a required skill of the high router. Sometimes it can be relatively easy but other times, especially when wet, quite desperate. Be sure to wear shoes with big tread and good ankle mobility so you can allow your ankles to twist into the hill (I like La Sportiva Ultra Raptors or Mutants). Poles are a must. In general, if vegetation is growing on the hill, you can traverse it, but still consider if you could cross to other side of the ridge, drop a little bit to a bench, or something else because extended sidehilling can be very fatiguing.

  • Passes: Passes are like your ticket to freedom. Passes are weaknesses in a ridge that allow you to cross back and forth, giving you varied scenery and aesthetic travel. Maybe it makes sense in one part to ride benches on the west side, then cross a pass and use snowfields on the east side.
  • Boulder Fields: Boulder fields are difficult to predict and really require local knowledge of their size and stability. I like to use boulder fields to gain vertical, but not to cover horizontal distance.
  • Avalanche Paths: Unless snow covered, these are a bad idea. Slide Alder dominates and will suck your spirit out of you.
  • Slabs: Some areas, like the High Sierra, are littered with slabs. Slabs are often the best terrain for high routes. The only concern with them is how steeper slabs can become dangerous when wet, from rain or snow melt above.
Slabs and snow, not the best combination.
  • Forests: Once again, forests vary greatly by location. In the Sierra and higher Cascade valleys, they are usually pretty tame and can actually allow pretty fast travel, although visibility is reduced. Near valley bottoms, there are often many blowdowns and tall brush, making travel difficult.
  • Burn Areas: Burn areas often provide relatively fast travel during the first few years after a fire because of no brush, but get very bad in the following decades as the brush regrows and downed timber covers the slopes.
  • Rivers and Streams: Rivers can be very difficult to cross without a bridge or good log, especially during peak snowmelt in the spring and early summer. Be considerate of this and try to cross rivers at flatter sections of terrain and higher up, where there is less flow.

  • Snowfields: Snowfields are your friend! Anticipate snow conditions by aspect and temperature: try to cross south facing snowfields earlier in the day and north facing ones later. Whether or not you do a route N-S or S-N can greatly affect the snow conditions you encounter. Even though common knowledge says it’s a bad idea, I often take just aluminum crampons and poles, confident I will not slip and need an ice ax. This is more efficient than using an ice ax on moderate terrain.
  • Glaciers: Glaciers can be very helpful in alpine terrain. Generally, try to stay higher on glaciers and in flatter sections. Convexities usually lead to a higher density of crevasses. Access at the tongue of a glacier can be difficult, especially with deep lateral moraines resulting from glacial recession. At the top of glaciers, watch for bergschrunds. People often ask me how I decided whether or not to bring a rope on glaciers. If you’re not sure, then bring a rope! But in all honesty, I research for late season photos of the glacier, look at trip reports, try to find information about how crevassed a glacier is. But if you’re at all uncertain, play it safe.
The Honeycomb Glacier is an example of one I crossed solo: very consistent grade, few convexities, plenty of late season photos available.

Research

There are tons of ways to research your proposed high route. Here are a few resources that I frequently leverage:

  • Trip Reports: Search the internet, on popular forums, and social media for trip reports of a similar route or specific area you are interested in. The photos and stories can be very helpful in informing your decisions.
  • Guidebooks: People think of the Beckey Guides as just for alpine climbing, but there’s actually “High Routes” in the subtitle! In other climbing guidebooks, approach beta for certain routes can directly relate to your high route plans. In the Cascades, owning the archaic “Routes and Rocks” high route books is a must.
  • Locals: It’s no secret that a successful high route depends on previous experience in the area. If you don’t have that experience, talk to locals who do. Even if you do, find more experienced travelers and pick their brains about routes they have done and how those trips worked out.
  • Maps: I am a big fan of caltopo for planning my routes. The “MapBuilder Hybrid” base layer is super useful because it mixes satellite imagery and a topographical layer, allowing you to see the topography and surface terrain as you draw your route. Turning on slope angle shading can help you see micro terrain features and evaluate the viability of certain snowfields or sidehills. You can even get projected current snow depth over terrain.
A blend of the topo map and satellite imagery allow for fine route precision. Here, we can stay off the boulder field while still following the natural flow of the terrain.
  • Satellite Imagery: Satellite imagery can reveal so much about terrain surface. This can help you tell if it is brushy, meadows, forests, boulders, etc. Additionally, you can leverage free Sentinel2 (a satellite) imagery to get up to date insight into snow coverage. Caltopo has even integrated this into their website!

Execution

After all the dreaming, the actual execution of the high route is so exciting and important. Obviously, a strong fitness base and variety of mountain skills – snow travel, scrambling, bushwhacking, boulder hopping – are paramount, along with navigation. Remember, no matter what line you drew on the map, the terrain is not going to be exactly what you expected, and you will have to route find and improvise on the way. Trust your instincts; even if they are not good, you will improve them.

A few general ideas to think about:

  • Bail Options: I always recommend having bail options planned and mapped in case you fall behind schedule, there is a rolled ankle, a section does not work, or you just are not feeling it anymore.
  • Speed: This will take some trial and error to learn how fast you can move in different terrain, but start conservative, like 25-50% of your trail speed. 1 mph can be good for a high route. Pace yourself. High routes are demanding.
  • Campsites: Keep in mind where you would want to camp (generally protected flat areas), where it is even possible to camp, and be adaptable to make sure you get a good night’s rest. Don’t get caught on an endless boulder field as the sun is going down.
  • Weather: Visibility and dry rock/heather is key to a successful high route. Pay close attention to weather patterns an don’t be afraid to bail if it is not looking good.
  • Gear: I generally advocate going light as possible. Sure, you can roll with 30 lbs on a trail, but hopping across boulders? That’s a different story. I try to minimize everything I can, from lighter sleeping gear to simply less water (make use of frequent water sources).
On the two-day Alpine Lakes Crest Traverse, I carried less than 15 lbs in a 26 liter frameless pack, allowing me to move quickly over any terrain.

Final Thoughts

In this article, I tried to lay down a framework and explain how I go about creating a high route; I didn’t want to tell you things you can or cannot do. Perhaps the most important part of a successful high route is creativity – the fearlessness to dream and to explore. Lowell Skoog, arguably the greatest ski mountaineer in Cascade history, once told me:

If you can dream it, you can do it“.

Sometimes, I believe that our greatest obstacle is not some steep cliff or intimidating glacier, but our own conceptions of what traveling in the mountains is supposed to be. In many ways, I believe that we are only limited by our imagination. If you have a clear vision of the experience you seek in the mountains and you take the necessary steps to prepare and execute, you will someday make that vision a reality. It is only a matter of time.
