Located on the east side of the Cascades, Blewett Pass boasts dry snow and easy access via a network of cross-country ski trails. Numerous fires that burned in the summer of 2012 thinned out much of the Blewett Pass area and left behind generously spaced trees that make for great skiing. There are three prominent features visible from Highway 97: Tronsen Ridge lies to the north and Diamond Head and Table Mountain are to the south. All three can be accessed by Upper Tronson Road or the Blewett Pass Sno-Park. The Blewett Pass Sno-Park is regularly filled with snowmobiles and their trailers; Upper Tronson Road has a plowed pull-out that will hold around 8-12 cars, accesses the same network of trails, and may be a better option if you are looking for a quieter experience.
From the Blewett Pass Trailhead, take the Haney Meadow Trail to the base of Diamond Head. From here you'll likely break your own skin-track up Diamond Head. If you are beginning at the Upper Tronson Road pullout, head southeast up the Tronson Road Loop to Sidestep Hill Trail and begin your skin-track up Tronsen Ridge. Gaining Tronsen Ridge provides access to open slopes and the glades that drop off of Table Mountain and Tronsen Ridge. There are many skiable aspects accessed from Tronsen Ridge, which makes the area a great choice when wind or sun become a concern.
Winter backcountry adventures can be dangerous outdoor activities that pose significant risks as conditions affecting safety (i.e. weather, snowpack stability, avalanche hazard) are constantly changing. Prior to engaging in these activities each individual should get the proper training to make safe decisions and be equipped to use avalanche safety resources and tools.
