Our original plan was Sasse Mt. and snowshoes, but we were driven southeast by increasing rain and winds. We chose a loop trip of Rattlesnake Canyon as a good alternative. To get there, go south on Canyon Road at the Ellensburg Exit from I-90 (note the Appleseed Restaurant is closed and up for sale!). Begin looking on your right after passing the 17-mile marker, to find a very nice US BLM parking area with toilet facilities and a swaying suspension bridge that will take you across the river and into Umtanum Canyon. These are not officially maintained trails, so prepare to keep a sharp eye out for the path. Take the first fork left into a draw and follow uphill, gradually traversing northerly and up steep ridges to the old Ellensburg-Selah toll road. Proceed along the rolling, hilly road toward the north trailhead, finding an optional cutoff about a mile or so south of the north trailhead that will head downhill toward the canyon, past an old cabin site (Barnes Cabin on the map), on an old jeep track and later descend game trails until you reach the flat, grassy meadow at the north end of the canyon. Here a well stamped boot path leads into a quiet land between walls of volcanic palisades where the meanderings of Umtanum Ck. create many crossings, changeable year after year. Often crossings are over beaver dams. The beavers are active this year and we counted two quiet, slick-surfaced wide spots where the little engineers were active. Flowers along the way--hedgehog cactus, larkspur, brodaeia, daggerpod, shooting star, bluebells, mission bells--not peaking just yet, but beginning to show. Down in the canyon it's quite warm, sheltered from the chilly, scouring winds of the ridge top. The trail occasionally crosses volcanic talus, winds through aspen groves, past great ponderosa, presenting delightful variety. An occasional campsite log makes a good resting spot. The old settlement foundations are still there toward the end of the canyon and the long-ago planted orchard, lilacs and quince bushes are blooming. We heard some favorite songs, larks and canyon wrens. Just one party met, who had camped the night before and seen Big Horn Sheep up on the canyon banks. One drowsy snake sighted. None of the many crossings was awful, just fun. We had a benign adventure in the sunlight while the west got storm weather. Est. mileage, 12 miles. Est. gain, 2,500. Go east in the spring -- but not after late May, since later there will be active rattlesnakes and poison ivy.
