Full Trip Report

I did a nice ski tour in the Naches Mountains with Chris VB on Sunday.  We started at Tipsoo Lakes and skinned around the southwest side of Naches Peak, and then eastward across the hillside above Dewey Lakes.  Our goal was Seymour Peak, on the opposite side of the valley.

While traversing through Naches Flats, we encountered a solo skier coming over a small ridge. It turned out to be Eva Meassick, whom I had encountered several years ago in pretty much the same location.  If you don’t know Eva, you really should.  She is 75 years young and serves as a volunteer backcountry ski ranger for Mt Rainier National Park.  Her current schedule involves ski-patrolling the backcountry 2 to 3 days per week throughout the entire winter and spring—always alone.

She admitted that this “relaxed” schedule reflected her growing dislike for the 4-hour round-trip drive from home;  until recently, she’d routinely patrolled 5 days per week!  I took her photograph, and she regaled us with stories of her past backcountry adventures, which included the second completion of the rugged Cariboo Traverse in Canada.

Once back on route, Chris and I descended to the Dewey Lake Saddle, then worked our way up to the Dewey-Seymour Saddle.  I skied, booted, and scrambled up the corniced ridge crest to Seymour’s summit for better views.

Later, we enjoyed a fast ski run down through Dewey Basin on good corn snow.

After climbing back up toward Naches Basin, we continued our counter-clockwise loop around Naches Peak.  This made for a more interesting return to Chinook Pass, and it afforded us a look at an impressive slab avalanche that had released closely below the summit.  We estimated the fracture crown to be 3 to 5 feet high—and not more than a week old.
