The Quest for the Cascade High Route

A Cascadian Dream

Ever since spending two magical weeks on the Sierra High Route, I have dreamed of creating a similar high route back in my home mountains, the North Cascades. But the North Cascades are even bulkier and more rugged than the Sierras, so I know that it will be a huge challenge. Daniel and I have started planning routes and hopefully this summer we will start doing certain segments. I will update this page with each exploration.

Steve Roper, the father of the Sierra High Route, had a simple vision: stay as high as possible without needing technical gear. This methodology has really captured my imagination. There was something so wholesome and beautiful about carrying minimal gear, staying high and off trail, and moving quickly above the tree line. I think what I enjoy most is that it makes me feel the maximum degree of freedom: unrestricted by trails, and unburdened by excessive gear and a heavy pack. This type of movement feels pure and simple, and it can take you to amazing places.

In the North Cascades, high routes are not as easy. We simply do not have the huge mile long flat basins above tree line and endless granite lakes of the High Sierra. Instead, we have huge, steep glacial carved valleys, jagged ridge lines, and a whole lot of brush. In many cases, travel in the high country is actually easiest when on snow or glaciers, so for this trip, we will have to make the exception that light glacier gear is okay. To avoid the glaciers of the North Cascades would be to remove the essence of the range, what makes it so wild and unique compared to the other ranges in the lower 48.

There is no doubt the Cascade High Route will be a very different adventure than the Sierra High Route. The lower 48’s two most extensive, impressive ranges are unique and so will these experiences be. Next, I will give a general overview of each section, as we have planned.

I90 to Deception Pass

There are a few ways to do the I90 section: staying close to either the Alpine Lakes Crest (Lemah to Daniel) from either the Middle Fork Snoqualmie River or Snoqualmie Pass, or an eastern route through the Stuart Range and Chiwaukum. In my experience, the eastern route would be challenging to stay high off trail because of the excessive steep choss in the Stuart Range and ruggedness of the Chiwaukum. Also, the Alpine Lakes Crest actually feels less traveled, with its own share of sparking blue lakes.

Currently, our route starts on the PCT from Snoqualmie Pass before branching off and climbing up over Chikamin. This is the beginning of a wild, remote off trail section across the Overcoat Glacier, beneath the Chiefs, over Hinman, and then up to Pea Soup Lake. Here, one could take trails back from Jade and Marmot Lake to Deception Pass or try a more direct route on the east side of Daniel, or go up and over Daniel from the north. More exploration will be needed to determine the best route here.

Deception Pass to Stevens Pass

This section could be very simple, cruising the PCT for a short section. But I believe there could be some beautiful terrain just east of the PCT. From the Robin Lakes (a true alpine lakes gem), I think you could traverse by the Swallow Lakes and Square Lake (hopefully not too much brush) and up to the Thunder Mountain Lakes (a true hidden gem) before descending to the PCT. This is not the most spectacular terrain, but still could be very pleasing.

Stevens Pass to White Pass

We have struggled with what to do in this section. The only feasible option that does not require dropping low onto roads or extensive bushwhacking is to simply take the PCT north. There is not a lot of continuous alpine terrain allowing for high route travel. The Monte Cristo Group to the west is beautiful and rugged, but getting there is convoluted and would require large sections probably just on a forest service road. East of the PCT has long lowland valleys. Maybe we will come up with a better idea in the future, but for now, our plan is to cruise the PCT.

White Pass to Cascade Pass

This section is where the high route really ramps up in terms of scenery and scale. The Glacier Peak Wilderness is my favorite place to hike and trail run, so we are calling this section the Glacier Peak High Route. The most obvious option crosses the Whitechuck and Honeycomb Glaciers, meanders through the wonderful Napeequa River Valley, crosses High Pass, Buck Creek Pass, towards the Lyman Lakes somehow, past Image Lake towards the southern end of the Ptarmigan and for the full length of the famous Ptarmigan Traverse. The second option goes completely over the summit of Glacier Peak to the Lime Ridge High Route, down to the Suiattle River Trail (possible resupply) and then the often-forgotten Bath Lakes High Route to join the southern end of the Ptarmigan Traverse. The former option stays high more consistently but the latter involves a summit of Glacier Peak. We are leaning towards the former because it travels through the wonderful terrain just east of Glacier Peak, home to silty blue lakes, deep valleys, endless wildflowers, and mighty peaks. This very well could be the most beautiful and diverse section of the high route.

Cascade Pass to Highway 20

There are a few options, but it depends where you want to arrive at Highway 20. We want to arrive somewhere near Diablo Lake for a Pickets Traverse, so naturally, the Isolation Traverse, an established classic route, makes sense. This traverse is extremely glaciated and even will involve a short rappel. It offers the option for some extremely aesthetic summits like Eldorado and Snowfield Peak. This is very alpine terrain, unlike anything else in the lower 48.

Highway 20 to Whatcom Pass

There are many places to cross the North Cascades between Highway 20 and Canada, but we are favoring a west side traverse through the Pickets, the most remote and rugged area in the lower 48. We just felt like not including the Pickets in the high route would be wrong. The Isolation Traverse ends very close to the Sourdough Mountain Trail, which can be ascended to Stettatle Ridge and traversed to the beginning of the Southern Pickets. There are many options in the Pickets Traverse itself, but we will likely stick to an easier option since this section is very challenging already. Regardless, we will end up at Whatcom Pass.

From Whatcom Pass, we think there is a high route that leads to the imposing, lofty Redoubt-Spickard group. This section will likely require some scouting, but it should work. The Redoubt-Spickard group is a fantastic way to finish the trip, a collection of 8000+ ft peaks with an aqua blue lake at the base. From there, one can either hike out the Depot Creek Trail to Canada or schwack down to Ross Lake and catch a boat ride back to Highway 20.


Another unique challenge is resupply points. Between US2 and Highway 20, no roads are crossed and no trailheads are even that close, with the exception of the North Fork Sauk and Cascade Pass Trailheads. Food could be left at these trailheads, but this brings into question the legality of such food caches. There is also Holden Village only ~6 miles away from the Lyman Lakes, and I think you could send packages there. Finally, Stehekin is not too far from Cascade Pass, although this is a substantial detour. For the northern part of the high route from Highway 20 to Canada, there are no easy resupply options, although we think this section will be manageable in a week.

The Challenge of the North Cascades

Even as we began to figure out the pieces to the puzzle, this high route will be extremely challenging physically, navigationally, and logistically. Hopefully, once we have answered the question marks and etched the dotted lines on the map into pen, we can give it a go in one long, epic adventure. We definitely consider this a multi-year or decade project, but climbers here know that the challenge of the North Cascades is one that can occupy an entire lifetime.
