To be honest, skiers like me usually avoid trails like the Salmon le Sac-Fortune Creek trail. But there's excellent scenery to be had, if you don't mind sharing the trail with skiers named Arctic Cat and Yamaha. Yes, this road is open to smowmobiles--I thought I'd tell you that right up front. But an ambitious overnight ski or snowshoe into the Wenatchee Mountains offers great camping, wooded trails among towering peaks, and sometimes drier weather than the west.

Start at the Sno-Park at the north end of Cle Elum Lake. Continue north on the snow-covered Salmon le Sac road 4330. Numerous side trips are available to you as you work your way up this valley. At about 7 miles take the Fortune Creek turnoff, to your right. So far, the road has been wide enough for snowmobilers to pass you. From here on, the trail is narrow and bumpy, and you risk disaster by being on their trail. I suggest dropping down toward the creek and making your own trail for the next 4 or 5 miles.
At about 13 miles turn south, following Fortune Creek instead of the trail, and you enter a broad valley. Campsites abound, and the noise will be gone by the time you get this far. Straight ahead are the Esmerelda Peaks. On your left is Ingalls Peak. This is a beautiful setting, with steep cliffs on both sides of the valley. Lake Ann is here somewhere, under 10 or 15 feet of snow. The slopes invite telemarkers to practice until they drop.
Stats: Sno-Park elevation 2300', high point as high as 6300'. One way 13 miles to Lake Ann.
Note: This is backcountry travel. Trails are often confusing or not evident in the snow, especially with snowmobile tracks leading everywhere. If you are not comfortable with map and compass, or you are not confident in your ability to handle a white-out, don't go.
Getting there: Take I-90 to exit 84 and drive through Roslyn, where "Northern Exposure" was filmed. Continue driving north past Cle Elum Lake, to where the snow closes the road. Sno-Park permit required.
Note: This is backcountry wilderness travel. Any trail can become very dangerous in winter conditions. You are responsible for informing yourself of the hazards and taking the necessary precautions. Please read Terms of Use.
