With 2 companions, I did a 4 day 3 night trip to Marmot Lake, Deception Lakes and Cathedral Rock. All of the trails are in excellent shape and the large pile of avalanche debris on trail 1068 to Marmot Lake had been cleared a couple of days before by a WTA youth work party.
The first day we hiked in to Marmot Lake, a beautiful spot, with good campsites and a gently sloping granite shoreline, great for swimming or just hanging out. With some trepidation, we headed up to Jade Lake the next morning. Although the route goes up a steep talus filled gully, it is well marked and the rock stable. There is a route on the left side of the gully that avoids some of the talus, but we only found it on the way down. Jade Lake is spectacular and reminiscent of the Canadian Rockies. It was the the highlight of the trip. There is a campsite nearby at No Name lake, but it would be a brutal ordeal to haul a full pack up there.
The next day we hiked to Deception Lakes, backtracking on trail 1068 and then heading north on the PCT. Expecting a series of lakes surrounded by meadows, we we're pretty disappointed when we got there. We had planned to spend 2 nights. We tried to hike up Surprise Mountain, but the trail quickly disappeared once we left the shore of the lake. Don't be fooled by solid green lines on the Green Trails maps. Some of these trails are hardly used and hardly ever maintained.
So after one night, we decided to spend our last night on the ridge near Cathedral Rock. The PCT between Deception Pass and Cathedral Rock was beautiful. We found a site along the trail at the edge of the meadow near the junction of the PCT and trail 1345. We had to walk about 5 minutes down the into the meadow to find flowing water. There are spectacular campsites on the ridge , but you would need to hike 10 minutes down trail 1345 to find water in a small lake or to the trickle of water we found in the meadow.
The last morning of our trip the weather changed abruptly. It had been quite hot and sunny. Within a couple of hours the temperature dropped almost 20 degrees and the clouds rolled in. By the time we reached the trailhead that afternoon it was raining.
