Copyright © Craig Romano/The Mountaineers Books West Fork Foss River and Lakes
Tucked in tight folds, big basins, and rocky cirques high above the West Fork Foss River are a bevy of big, beautiful alpine lakes-one of the highest concentrations of alpine lakes in the entire Alpine Lakes Wilderness, actually. You can spend days here, and many do, but day hiking to several of these aquatic gems isn't out of the question. Just prepare for a tough slog over rough terrain. And prepare for some of the finest alpine scenery this side of Stevens Pass.
How many of the five lakes lying along this trail you choose to visit will depend on your stamina and determination. While this hike isn't the longest in this book, nor does it involve the most elevation gain, it does rank among the toughest. Much of the way is over rock-lots of rock. And much of the climb comes at once in a brushy section fully exposed to the sun. Making matters worse, the first mile of this trail is absolutely awful. It involves stumbling over what in essence is a dry (or not) rocky streambed. But if you can psych yourself up to get up and over these obstacles, you're in for a real treat. These lakes are among the biggest and most beautiful within the entire 393,360-acre Alpine Lakes Wilderness. Immediately entering wilderness, the trail begins in a lush mossy river bottomland. In the autumn of 2006 the trail became a river channel when the West Fork Foss flooded. Tread damage was extensive, and this part of the trail is a real mess. Hopefully by 2010 the Forest Service will have received funding and the Washington Trails Association will have assembled a work team to help rehabilitate this popular path. In 0.5 mile come to what may be a tricky or impossible river crossing. The floods of '06 destroyed a bridge here. In the summer of 2008, a log was in place across the main river channel, allowing safe passage-but this could change. Once across, continue upvalley, passing some of the largest trees this side of the redwoods. Carefully negotiate through a recent rock-slide area ("the fall of 2006!"), and at 1.5 miles come to Trout Lake (elev. 2000 ft). A shallow lake set amid cliffs and graced with groves of hemlock, it's a popular backpacking destination among anglers and families with children. Beyond Trout, trail damage is minimal, but the going gets tough. Paralleling a crashing side creek, the trail furiously climbs over rock and brushy slopes out of the deep valley. Following the waterway upward, you'll soon come to a spectacular waterfall. Then, angling right, the trail works its way over the headwall from whence all that water rages. Now in cool forest of yellow cedar and mountain hemlock, carefully cross a side creek on a snow-damaged bridge and continue upward at a saner grade. At 3.5 miles reach a junction (elev. 3850 ft). The trail right leads 0.2 mile up a steep and brushy route to often overlooked Lake Malachite (elev. 4089 ft), set in a big cirque. Continuing on the main path, reach Copper Lake (elev. 3961 ft) in 0.25 mile, just after crossing its outlet creek above a set of falls. Call it quits at the grassy outlet, where you can sit and stare across sparkling waters fed by snowmelt cascades, or keep exploring. The trail hugs the lake's rugged eastern shore, revealing fine rocky overlooks among groves of ancient trees. At 5 miles, after passing through heather meadows, reach the next aquatic gem, Little Heart Lake (elev. 4204 ft). Access to this body of water, often littered with avalanche debris, is at the campsites near the outlet stream. To get to Big Heart Lake, the most beautiful yet of the West Fork Foss lakes, keep following the trail, heading about 700 feet up a steep ridge and then dropping 350 feet off of it. Enjoy window views north of Trout Lake in the valley below and Glacier Peak hovering in the horizon beyond. Big Heart Lake at 6.5 miles (elev. 4545 ft) is set against a backdrop of rocky ridges and snowcapped spires. The large logjam near its outlet stream cascading into the valley below makes for an ideal spot for sunning, snacking, feet-soaking, and savoring all of this beauty. Rest up. It's a rough journey back, too.

A great and quiet hike. I only ran into two groups of people during the full trip to Lake Big Heart and back. Some how I managed to miss lake little heart. I'm going to guess that was thanks to a snow detour of two. The snow is getting very tender. You really need to be careful after Lake Copper. The trail is in needed of some serious marking and trimming near Lake trout. Coming it wasn't a problem but going it wasn't much fun to try to decoded. This is currently designated a wilderness area so make sure you check in with the ranger station.

I wanted to take my daughter on a hike we could make as long as we wanted, and Foss Lakes seemed like a great idea. I hadn't been there in over 8 years and was looking forward to it.
The forest road to the trailhead has quite some potholes in it, so careful zigzagging is advised. The trailhead now has a very nice toilet and the trail itself starts from a different location. I used the old start and found some dozen yards in that there was a new trail being constructed parallel to the old one. Quite some work has been done and it looks really nice. Thanks to those involved. Like the sign at the trailhead says, the bridge is out. There is a good big log that can be used to cross the river. It can be slick if wet, but otherwise should not present a problem. It is marked with tape. The trail is in very good shape, although the new growth is trying to take over the trail again. You can tell that it doesn't get as much use as some of the trails in the I90 corridor. In two places the rocks under the trail have given out and care is required when crossing these spots. It looks like these parts of the trail can slip down the hill. Both areas are before you get to Trout Lake. The trail beyond Trout Lake is gorgeous and steep. The roar of the waterfall is constantly with you. There are still some patches of snow close to Copper Lake, and some parts of the trail there are under water. No problem unless you are wearing sneakers. Copper Lake is almost completely ice free. We stopped here to have our lunch and found it to be the right place to turn around. A beautiful hike.

Synopsis: West Fork Foss River: #1064 Trout, Copper and Malachite Lakes
Great TH toilet block, first 400 yards rerouted on new path, log bridge partially submerged but passable. Great brush work from Trout lake up to 3200' contour. Overall trail in great shape - dry, virtually no mud one or two old blow downs easily navigated. Snow at 4000'; last 4 yards to Copper over mushy but compacted snow. Log jam crossing exciting due to high water level of lake, some are just floating! Camp sites practically all melted out. The Hike: Wanted to make the most of the first decent weather weekend this year since March (sheesh!) and hopefully before the bugs emerged. Long time wish to overnight at Copper took me there on the morning of Friday 25th June. FS road somewhat pot holed requiring some care to avoid the big ones. Only 1 other car at TH, sign board still wrapped for winter (wrapping was gone when I returned). Evidence of FS maintenance on what is arguably one of the finest hikes off hwy 2. Clean new toilet block and a rerouted initial path alongside old stream bed path for about 400 yards. Uneventful through to the large log bridge, which since last year has sunk on this side of river bank making the first 6' wet with some other logs hindering access to it (See pic). Water volume causing log to be splashed over some of its length making log look very slippy, but it isn't and with care is reasonably easy to navigate. Brushy ascent through clearings up to Trout, no other soul in sight and very peaceful. Now comes the huge improvement on this "unmaintained" (that's what the TH sign says) trail. The shrubbery from Trout onwards up to the base of the Copper Lake outlet falls at about 3200' has been truly cut back opening up the entire tread and halting the gradual decline of the trailbed down the slope. New foot trails are already being created and this has greatly improved the access and the general feel-good factor of this trail. The falls at the head of the valley are magnificent and a full volume from the snow melt and fill the steep sided valley with booming thunder. After 3200' the brush work stops (FS please, please, please continue your work in the upper stretches were shrub incursion and trail erosion will soon make this trail a real pain). As the trail levels out above the falls the area is very wet and boggy but the trail remains mostly dry. At 4000' and some 1/4 mile from Copper lake the snow line is reached and there are long stretches of compacted but soft snow to negotiate. Just watch out for those pesky rock melt outs under the snow. Getting to the lake shore at the log jam is a bit of a bash and then working out a good course through the log maze if fun, and occasionally you'll get a floater or roller, so I strongly advise hiking poles and testing everything before committing - but it's doable. Many campsites across the log jam all of which are melted out. Uneventful but awesomely peaceful first night at Copper. My initial intention was to try for Big Heart Lake but the snow fields at the lake soon dissuaded me, but I did a foray over patchy snow fields round to Little Heart Lake. On Saturday, the day dawned with patchy clouds and mist and I thought I should return back home, so packed up and set off but at the falls the sun broke through and promised a glorious day and nature reminded me of its presence as a hornet stung me on my ankle. So as I had supplies for 3 days I turned tail and regained the lost 200' back to the Malchite TH. (This is flashed with an orangle tag, but the TH sign is easy to miss as it is high up (about 12') on a large tree and easily missed. The trail up to Malchite was great considering it's only a boot trail and I expected much snow, but there was none until you hit the level section approaching the lake. In fact access to Malchite is much easier than Copper. However, the log jam was just too flaky for me but all the campsites were on the far side of the outlet (many floaters and rollers). So I backtracked down the outlet to a point where the river starts its tumble down the valley and there are a set of wonderfully flat and non slippy rocks that can be navigated in boots without geting your feet wet, so I made it. There was one other party in the traditional camp site, most of which was buried in about 4' of snow. So I located a spot that I had scoped out last year and with the removal of a small amount of snow uncovered a lovely flat area with a great hanging tree right next to it (See pic). It's difficult to say which is more beautiful Copper or Malchite, but who cares they are both stunning and I spent another gloriously peaceful day there and the weather obliged with a sizzling cobalt blue sky and high temperatures; I could almost see the snow receding under the blaze of the sun. Sunday dawned with an overcast sky that stayed with me all the way to the car, so this was a blessing and the log crossing is much easier coming back. Oh and did my original idea work out? ie no bugs - you bet. I got hit 3 times in 3 days, so I would count that as bug free considering how bad the Foss river can get. Go now, while the bugs are still unsure - the trail is awesome and the sights magnificent. Day hike

Decided to try out the West Fork Foss Lakes today, hoping that conditions were doable seeing as the last report for this trip was May 1 and deep snow was still lingering around.
The road up was decent. There were numerous potholes, some monsters, but they were all pretty avoidable with some creative driving. We got up no problem in my old Subaru. The trail conditions in the first mile were pretty shabby as previous reports said, including washouts, landslides and missing bridges. Good news though: we ran across a WTA crew taking a lunch break after working hard laying down some stones as a base for a reconstructed trail. It was looking good so far! Trout Lake was gorgeous, and the trail up to Copper Lake is almost fully snow free, but the 1/2 mile before the lake still has a week or two of melting to do before it's all gone. Some posthole hazards, so be aware! Copper Lake was absolutely stunning with the lingering snow on the mountains! The lake itself is still frozen, but that only added to the scene. We had plans to go to Malachite Lake as well, but time wasn't too allowing for us, and a small short dousing of rain helped motivate us to head out. All in all a great day! Lots of flowers in bloom!

The forecast was poor, but we decided to try a day hike to Trout Lake and Copper Lake.
The road that turns left off the Foss River Road is marked poorly (No FS road #) We turned around and arrived at the trailhead around 10am and we were the only vehicle in the parking lot. We didn’t see any other hikers on the whole trip. In years past this would be considered an easy family hike. Not so this time. The trail is rough with lots of roots and rocks to trip over. The log bridge is gone, but there were some slippery logs to make passage possible. One large avalanche requires some bush whacking but it’s doable. There is also a place where the trail is gone due to landslide. It isn’t too difficult to get around but if you go too close to the edge the ground under your feet tends to sluff off. Once at Trout Lake it’s as beautiful as ever if you could ignore the steady rain. There is no snow all the way to Trout Lake. Back on the trail again headed for Copper Lake it was snow free for about ½ way. The second half had slush in the tread making footing a bit sketchy. Suddenly the snow became deep (4 to 6 feet) just before the stairs. The log bridge over the stream that exits Lake Malachite has the rail gone over most of the span. With snow on top we were able to cross with snowshoes without slipping off. We only made it to about ¼ mile short of Copper Lake because the deep snow was full of snow bridges and we were unable to easily identify safe passage. Overall it was a great hike. Lots of Trillium in bloom and the trees are just starting to sprout leaves. The waterfalls are spectacular. There was plenty of solitude. We just had to deal with the steady rain. Once back to the car (tired and wet but no other vehicles) we drove into beautiful sunshine as soon as we got on paved road. |
