This is a report of a July 17, 2004, one-day, 25-mile loop hike connecting the West Fork Foss River trail #1064 through Trout, Copper and Big Heart lakes with Chetwoot lakes, Tank lakes, and back down the Jewel lakes, Necklace valley East Fork Foss River Trail #1062. Take Hwy 2 east past Skykomish, then up the Foss river FS road to the trailheads. Many thanks to Meadow Man who wrote a trip report on this loop on Aug 14, 2003 that gave me great guidance during this epic 18 hour trek. I will leave off some details which you can get from his report. I have about 40 pictures of the hike you can see at: http://www.whitefamily.bankslake.com/archives/2004/2004-07-17- kirk-big-heart-lake-loop-hike/index.htm The attached pictures show us at Copper lake and then Joel above Angeline lake almost reaching Little Chetwoot lake. As a scoutmaster in recent years I have led scouts backpacking up to Copper and Big Heart Lake several times, as well as up into the Necklace valley to Jade and Emerald lakes. But I always wanted to complete a single loop hike connecting these two great lake areas. I tried once from each direction from Foehn lake heading west, and Big Heart heading east, but was always stopped by snow too deep to trudge through. Now though the conditions are ideal this summer with the snow level at 5,400-5,600 feet or higher and good weather. Here is the Report: I went with a 25 year old friend Joel, who would be the safety buddy for my 47 year old body. Our goal was to train our legs for a Mt Rainier summit climb in 3 weeks, of which I have completed 5 successfully and Joel none yet. We camped Friday night at the Trout lake Trailhead of #1064, and awakened to a beautiful blue sky on Saturday. We parked the car in the lot, not finding anyone to hitch a ride to park it at our destination lot at the foot of trail #1062, East Fork Foss. I would later pay the 2.5 mile price for that mistake. We did not get started till 8 AM, but only carrying daypacks with food, water, ice axes, and rain gear, so the 1.5 mile hike past Trout Lake (2,100 ft) was easy and lovely, but the always sweaty 2.0 mile, 1800 ft climb up to Copper lake, exposed to the morning direct sun, was quite warm bordering on brutal. Copper Lake (3,961 ft) was beautiful, and despite a few bugs, was a nice picture postcard place to take a snack break. Mosquitoes were all over this hike and we used plenty of repellent to keep them at bay. No obvious bites, but they got me 40 times through my shirt at the shoulders I came to find later. Spray there too next time. We then headed up the easy 1.5 m trail to Little Heart Lake (4,204 ft), and then the 1.8 mile 700 ft elevation up and around the ridge and down a bit to Big Heart at 4,545 feet. The time from the car all the way (6.5 miles) to Big Heart took about 4 hours. No snow anywhere and the trail in great shape. We ate lunch at the logjam outlet with the thundering falls singing in the background. Big Heart is one of the best short backpack trips in the Alpine Lakes as it does not attract large numbers of campers due to the effort to climb there, and the lake is large and excellent for views, day hikes to nearby peaks, as well as rock jumping and log rafting. Our next destination was Chetwoot lake and I had heard several descriptions of how you could just climb straight south over the 5,400 ft ridge between Big Heart and Angeline Lakes to get to Chetwoot. I had done this partway to some degree on past hikes but never found a distinct trail. This time we hiked straight south until rock cairns and a well worn small trail took us east clockwise around the ridge, then south on the eastern ridge side to an Angeline Lake lookout and cliffs, then a quick switchback west up to the saddle in the middle of this ridge between Big Heart and Angeline. From there scattered cairns and some trail led us south towards Chetwoot. From Big Heart onward to Tank Lakes this is steep, scrambling and ducking type hiking which would be laborious with a pack on, but doable I suppose. Hiking straight south we hiked up random snow patches and rock in a lovely area with views of Big Heart's south end, until we ended up passing a small lake on its west side. From here we were unsure what a now visible lake to the east was: had to be either Chetwoot or Angeline still, but it was bordered on the east by steep cliffs so looked like Angeline to us. Our GPS and maps helped greatly to determine finally what it was by size and by our hiking direction on the GPS . We had to hike toward it to determine it had a north end outlet and thus was Chetwoot (4,900 ft). The hiking time from Big Heart to Chetwoot was 3+ hours for only about 2+ miles - it was THAT rough with day packs. Note to self: ALWAYS have a good GPS receiver when doing bushwhacking hiking where the trails are not on the map. At the minimum have good maps and an altimeter. We had all of them to cross check each tool. It literally saved us hours of wrong-way hiking and probably was the key thing we needed to complete this hike safely. Crossing the exit stream out of Chetwoot (very scenic camp site) we headed straight east and up toward what the map and GPS said would be Little Chetwoot lake. Unfortunately there is a ridge guarding Little Chet which is in a NE opened glacial bowl. We ignored Mountain Man's directions that were vague on this point and climbed straight east and up to the ridge crest, through rock and some snow patches ( Ice Axes were used here for added snow traction and safety though not too technical or dangerous), to 6,000 ft and the ridge top. There we saw Little Chet way down below at about 5,400 ft. We scurried down a fairly etchy descent into a perfect glacial bowl and side traverse to the outlet of LC in very loose rock scree all the way (no snow at all - was sun exposed) and then to the far east side of the lake. We went up to 5,700 feet and headed around the north ridge of Iron Cap mtn, until we had to decide to chance the rocky cliff advance or handclimb up and through a small light-colored rocky gully to get some tree and heather covered terrain to continue on. We chose the gully, and despite risk of knocking small rock down on each other we were up it quickly and had a safer, though still steep, cliff traverse around the ridge. The trees and heather were obstacles but comforting to hang onto and hike through with the slope being steep and cliffs awaiting any stupid moves. We continued through this southerly traverse, finally descending to about 5,300 ft and a ridge running south to east then to NE that we kept on the top of. Huge open snow fields to hike through at this point but fairly flat, and solid: no post-holing at all. Excellent views east of a huge rocky bowl, and Otter lake way below to the NE and North, and waterfalls coming off the opposing ridge from Bonnie and Tank Lakes. From the ridge we hiked on you can also see clearly the Middle fork Snoqualmie river way down south at 3,800 feet as well as the magnificent spires of Chimney Rock, Overcoat Peak and Summit Chief Mtn all about 7,400 ft tall across the river valley. We even saw real people on the trail way below which was comforting to know we could have bailed out on the loop hike and descended to a well traveled route if ever in real trouble. Staying on the high point of the ridge we hiked N-NE up gradual slopes (no trail or markers anywhere) until we finally saw some cairns at about 5,600 feet that were not much help as they led us, then disappeared. But they did confirm we were close, so we used the GPS to guide us almost straight north from that point climbing on rock till we found the lowest Tank lake at about 5,850 ft. That was a big relief to confirm (by an excellent GPS on-screen map) that we were walking gradually uphill past Tank to the other Tank lakes. By this time it was after 7 PM and we tried to motor NE starting downhill to 5,700 ft Foehn lake which is very small, like the Tanks, then spotting an occasional cairn and randomly climbing down to Opal lake at 4,800 ft. There is no real trail here and it is very much hit and miss where it is hikable due to streams running everywhere. This was about 7.5 miles from Big Heart over some very rough and minor risky, but outstanding view-filled ground. It took us about 4 hours to hike from Chetwoot to Tanks/Foehn lakes. We found what we thought was Opal Lake (it was really Crown lake)and our green trail map said the trail was right on its west shore, where we found nothing, so assuming stupidly the lake had risen over the trail, we bushwhacked through rock and tree to the end of the small lake. There we found no trail so searched in vain, and finding nothing, just plowed ahead north watching GPS and looking for tread. We should have headed west just 50-150 yards and would have found a well beaten path along the west side of Emerald Lake, an old log cabin I recalled from years earlier, and the clear trail to Jade lake, then down and out. But instead we mistakenly got too far east, mistook Crown Lake for Opal, and our Topo and GPS maps being incomplete, we could not self-correct early on. Instead we found rockslides and trees, clear enough to pass through and ended up on the south shore of Ilswoot lake at 4,590 ft. Much to our dismay we were far from the main trail and being 8:30 PM it was getting dark. So we trudged back west uphill and over a ridge, spotted some campers already snug in their beds, asked where we were and how to get to the main trail. They directed us to the east shore of Emerald lake, where more snuggy tenters told us how to get out to the trail and down to Jade Lake. I've rarely been more envious of backpackers who had their beds all made and were headed to sleepy land, while Joel and I had 3,000 vertical feet to descend and almost 8 miles to get to the East Fork Foss parking lot... IN THE DARK. Luckily we were smart enough to pack headlamps that lit the way, though the trail lost itself a few times from us, but we just had to keep putting one boot in front of the other for several thousand steps. Much of this trail down to the East Foss is in creekbed so very steep and awkward. After crossing the Foss River it is a flat 4.5 mile out but we saw nothing in the dark to report. We started down from Jade lake at 9 PM and arrived at the trail end at 2 AM (8 miles in 5 hours with few breaks), 23 miles from the morning start- Bushed, beaten and angry at biting off more than we should have maybe chewed, and at getting lost in the Necklace Valley lakes which wasted time, energy and precious daylight. From here I told Joel to take a nap while I trudged from 2-3 AM over to the West Fork trailhead to get the car and get us out of there. We called our wives once in Cell range on Hwy 2, and they forgave us our lateness and the delayed calling. My wife knows the drill and told Joel's wife to not panic till after 3 AM as I am always later than planned. Driving home was totally impossible so I stopped at a park-n ride in Kirkland to sleep 45 minutes before safely returning to Tacoma, where I crawled into Bed at 6 AM. Then up at 10 AM for church to say thanks for all the Divine protection as well as the fantastic sites we witnessed in the proceeding 24 hours. All in all a spectacular hike if one is up for it. Recommend starting VERY early in the AM (it was daylight at 5:30 AM) and bring GPS, Axes, repellent, headlamps, and a good camera. The sights are astounding. Better yet, pack overnight gear and take it slow and enjoy the experience longer.
