Did a loop from Icicle Creek TH along Icicle Creek to Frosty-Wildhorse, and then from Frosty Pass along the Icicle Ridge Trail to Chatter Creek and out at Chatter Creek TH. Camped at Upper Florence Lake. 

Route is snow free, other than a couple easy snow crossings (no spikes needed) at the top of the Chatter Creek Trail below Lake Edna. 

If you do this loop, a few things to be aware of:

The Icicle Creek to Frosty-Wildhorse route up to Icicle Ridge is super easy until the Frosty-Wildhorse junction. Flat shaded trail all the way to the junction. The bridge is indeed out at French Creek junction, and also the second bridge about 5.5 miles in crossing over Icicle Creek. I used the stock ford which was about shin deep and waded across at French Creek. Walked over the second broken bridge (very slowly) which felt fine. Broken but stable enough. 

The climb to Frosty Pass up Wildhorse Creek Trail is tough, mostly due to how overgrown it is. Shoulder height brush totally obscuring the trail for miles and miles as you ascend. I used a trekking poll to move brush out of the way to see the trail hidden beneath it quite often, and consulted a GPS to be sure I was on trail consistently. It was a full on bushwhack at times. A few ticks tried their best to get me, but I brushed them off before they could do any damage. I think wearing a long sleeve wicking shirt like a sun hoody, and leggings or pants, are an absolute MUST on this section.

The Icicle Ridge Trail from Frosty Pass to Upper Florence Lake (and all the way to Cape Horn as well as down to Lake Edna below Cape Horn) is super easy to follow and stunningly gorgeous. Panoramic mountain views that make the climb totally worth it! Wild flowers a plenty in the meadows. Some of the best scenery in the state in every direction you look, and you'll likely be totally alone up there. I had total solitude at Upper Florence Lake. Great campsites at the lake that have nice wind cover as well. The water in the lake was WARM! Amazing place that I cannot wait to visit again.

The descent of Chatter Creek from Lake Edna the next day was a KNEE WRECKER. But the views are amazing. Some route finding was necessary across the boulder and snow fields at the start of the descent, but otherwise the trail was easy to find. If there is any advice I can give you is that hiking up the Chatter Creek Trail is a fitness challenge I would not underestimate, even for the fittest people. I was glad I was descending rather than ascending. The trail is extremely steep, the trail narrow and sometimes overgrown, and it will take a LONG time to go up this trail if you choose to do that. I would personally go up Wildhorse via Icicle Creek or White Pine or even Chiwaukum to make Icicle Ridge, rather than ascending Chatter Creek. Descending it was hard enough!

Overall an amazing trip up to an infrequently visited area that is well worth the challenge to access for the views and solitude! Highlights are Icicle Ridge Trail from Frosty Pass to Lake Edna, especially Mary's Pass, Lake Mary, Upper Florence Lake, Cape Horn, and Lake Edna. Stunning views descending Chatter Creek. Lowlights are the bushwhack up Frosty-Wildhorse Trail, but would still choose to ascend via this trail (or White Pine to Frosty-Wildhorse, or Chiwaukum) over ascending via Chatter Creek!

I did this as an overnight, but an additional night would have been nice just to be immersed a little longer in this stunning place, perhaps visiting some other lakes in the area like Augusta for a night. Have fun out there, be safe, and leave no trace!

A delightful alpine-view sandwich of a loop trip, with brushy bread.

Trail 1580, Chatter Creek - Quite brushy, intermittently, but if you can squeeze through the growth you are rewarded with excellent views once you start climbing the ridge at the northwest end of Chatter Creek basin. North of this ridge to the junction with 1570 was the only section on this trip that was a little hard to follow, but not bad. There were a few small snowfields, easily crossed, and cairns to follow.

Trail 1570, Icicle Ridge Trail - At the junction with 1570, turn left (northwest) and head up to stark Lake Edna. A sign leads to an open toilet with a view. A bear container is a must if camping here; there's no way to hang a bear bag on what few tiny trees are up here. The section from Lake Edna to just before Lake Mary was absolutely gorgeous.

Trail 1592, Frosty-Wildhorse - Lake Margaret is the least alpine, the least scenic, and the most buggy of the four lakes on this hike (Edna, Upper Florence, Mary, Margaret). But because I got high off altitude and views and wildflowers and wanted to cover a lot of distance my first day, I ended up there. The Frosty Creek drainage below Margaret is pretty wildly overgrown. It swallowed me up and spit me out the other side. It's a good place to roll an ankle, because you can't see the trail a lot. It's a great place to get soaked by morning dew. And it would seem to be an excellent place to be a thirsty tick, but I lucked out and got none. There is a freshly-dead deer nearby the trail on this section, after the unruly vegetation and just before the switchback. Be alert for wildlife that may be in this area to dine. Props to a trail crew working on repairing trail on this switchback.

1551, Icicle Creek - Right after the junction of 1592 and 1551 the bridge over Icicle Creek is broken, but can still be carefully walked across. This trail is gloriously easy, brush-free, shaded, and zen-like. The bridge over French Creek is out, mostly destroyed. One could probably get across it but I crossed on rocks instead. 

Road-walking - Was luckily short. I was walking back to Chatter Creek trailhead -- as I hadn't planned this loop trip, I'd only planned on going to Edna and back, but kept going far enough that it made sense to just keep going -- but some wonderful fellow hikers who I'd met briefly on the trail offered me a ride.

Same beautiful trail. Tiny bit of snow on the icicle creek side. Wouldn't recommend going over to the north/Ida lake side of that first pass for the next couple weeks unless your prepped for decent snow pack.

Wildflowers starting to pop up, it's gorgeous with the patchy snow up there. We camped lower though because it's so nice down by the creek.

**I left 2x cork-handled, orange, black-diamond hiking poles in the parking lot on the levy / creek side. There in the first parking spot just to the right by the trees when you enter the lot. If anyone sees this I'll pay you to ship them back to me, or can come pick them up if you're in the seattle area. Thanks! Joednelson@gmail.com 

Beautiful trail, easy to follow, and great views along the way!

The majority of the incline is mostly snow free. The top mellows out, with an inch of snow or so, and then steepens again to the saddle. This steep section had 1-2 inches of snow that was quickly melting in the sun and turning the trail into a muddy slip and slide on my way down. Managed to keep the seat of my pants mud free and made it down without wiping out!

10am - 4pm on a sunny Saturday and only saw 2 other parties.

A great rainy hike, it's quite steep at times. The best time, amazing views.
