This is loop 47 in the Mountaineers ""Best Loop Hikes"". The book says 8 hours, GrnLkHiker did it in 6 on 8/15/07 but it took us 10. Maybe our mistake was taking it clockwise, oppposite to what the book recommends; our older knees would rather go up steep slopes than down them. We did a lot of extra miles and elevation gain trying to find the trail up Jack Ridge and down to Trout Lake, and we also took an unintentional side trip. Be forwarned that #1557 is overgrown, there are many massive blow-downs, no signs and many boot tracks going who knows where. Also, this hike is almost entirely in the forest, it's a beautiful forest but we were longing for some views after a long day and when the trail left the wilderness area and entered a clearcut above Trout Creek, the opening was welcome.
Jack Creek Trail #1558 is a fine trail along a pretty creek, we passed two fishermen, the only folks we saw all day. After 3 miles there is a sign for #1557 up Jack Ridge. The trail is immediately engulfed in thick brush, but passable. Soon you cross a creek and then switchback steeply up through more brush. Be careful not to get off on a dead-end boot track; we did twice, back-tracked one time and bushwhacked back to the trail the second time. You should hear the creek to your right most of the way up, and if you haven't switch-backed in about 50 yards you probably missed one. Lots of brush and blowdowns. The only views are from the top of Jack Ridge, not spectacular but nice to be in the open.
We missed the trail down to slime-green Trout Lake because a boot track continues south along the ridge past it. When you see Trout Lake, look for a sharp switchback to the left just before an avalanche slope; there is no marker. Not realizing we had missed it, we continued south along the ridge and then up several hundred feet above a burn where the views are better; this side trip added an hour or more to the loop. The #1557 down to Trout Lake starts out okay but soon disappears beneath some massive blowdowns. We thought we had missed a switchback and backtracked before figuring out we'd just have to go over/under/around several huge trees. After bushwhacking for half an hour, we found the trail again. The lake is very marshy and difficult to approach because of all the brush and logs. We found the outlet and crossed it and then looked for #1555 heading north. There are no markers and I'm not sure what we took was a trail. We followed the east side of the outlet stream through a lot of muck and brush until the outlet stream meets Trout Creek, this is also the junction with trail #1554. Here we crossed back over the outlet stream and there are trail signs, though not particularly helpful ones. Find a trail going north with Trout Creek heading downstream on your right. This is #1555 and it is easy to follow along the north ridge above Trout Creek and then west back down to #1558.
Fine weather, no bugs, plenty of water for our filter bottles and a few berries too.
