Left PCT trailhead at Snoqualmie Pass about 7:00 am on perfect, cool, clear and sunny day. Patchy snow and blow-downs to junction with Commonwealth Basin Trail, but trail is in good shape. More snow patches and blow-downs to where PCT crosses the winter avalanche runout area from Kendall Peak. Snow cover becomes 90% as trail climbs in the trees to Kendall ridge. Several large blow-downs make following the trail difficult. Trail is mostly snow free traversing the Western facing upper-talus slope of Kendall Peak. Once the trail climbs the shoulder and turns onto the North facing slope, snow is deep and steep to the Katwalk proper. Ice axe is a must to cross the steeper snow chutes. I used crampons as the snow was still to hard to kick steps. A slip while crossing the chutes would result in a long, painful slide/fall into upper Commonwealth Basin. The Katwalk is snow free but right after the PCT totally disappears under a continuous, deep-snow field all the way to Ridge Lake. Looking through binoculars it looked like the PCT is not hikeable above Alaska Lake and across the face of Chikamin Peak. I would guess about 3-weeks til it melts out. Round trip to Katwalk covers about 10 miles and 2,900 feet.
