Commonwealth Basin Snowshoe

Click for larger image

The Commonwealth Basin snowshoe route starts at the Snoqualmie Pass ski resort and follows Commonwealth Creek northeast towards the base of Red Mountain. The winter scenery along the way is varied and spectacular, ranging from snow-covered foot bridges in an intimate forest setting to frozen waterfalls to wide-open mountain vistas. And the higher-altitude climb up the flank of Red Mountain, pictured in the distance above, yields even better views.

Portions of the route follow a section of the Pacific Crest Trail (PCT) Section J, between Snoqualmie Pass and Stevens Pass. (The PCT is a 2,653 mi (4,270 km) long-distance hiking trail extending from the southern to the nothern US border through the Cascade and Sierra Nevada mountain range.) We’d planned to park in the PCT trailhead lot to make the snowshoe hike, but the lot and road leading to it were snowed in. We instead parked with the skiers and walked a short distance before donning our snowshoes. Within feet, we left the busy and noisy ski area just off the I-90 highway for a hushed and tranquil woods covered with snow. We saw few other people the entire time, and really enjoyed the winter scenery and views.

Less Snow

We’re snowshoeing into Commonwealth Basin today from a summer trailhead for the Pacific Crest Trail. The summer bathrooms at the trailhead are closed for the winter and buried in snow, as is the entire parking lot and short entry road. We instead parked near the ski resort and walked a short distance over the snow to reach the trailhead.

Alpine Lakes
We’re just crossing into the the southern boundary of the Alpine Lakes Wilderness Area that encompasses over 400,000-acres (160,000 ha) roughly between Snoqualmie Pass and Steven’s Pass. Alpine Lakes contains some of the most rugged and beautiful topography in the Cascade Mountains, with steep mountains and over 700 lakes. With 47 trailheads and 615 miles (990 km) of trails, the area is very popular in the summer, particularly the Enchantment Lakes region where a lottery system is in place to obtain an overnight camping permit.

Snow Bridge
We’d followed an ad-hoc trail north along the west side of Commonwealth Creek, but wanted to make a loop and return along the Commonwealth Basin Trail along the east side. Here James is crossing a snow bridge across the creek and climbing up the other shore to reach the trail.

Low Fuel
We’ve loving the remote telemetry available for our new truck. Here the HondaLink app indicates the doors are locked, the odometer reads 2,248 miles (3,617 km), and we have 14 miles (22 km) of range left on a near-empty tank. That’s by far the lowest we’ve ever let the fuel get. Fortunately we’re in North Bend and about to fuel.
