ghsmith76 There is a glaring misprint or failure to edit in your description of Timberline Trail. You write about starting at the lodge, going counter-clockwise and entering Zig Zag canyon. That would be Clockwise. Counter would be crossing the Smith River first, on the way to Copper.
Other than that, I think you chose some doozeys. Wise man. I have to ask, if you were picking from the NW, why did you leave off the 96 mile trek around Rainier (Wonderland Trail)?

The only one of these that I have done is Spider Gap/Buck Creek. (Well, I've never actually done that exact loop, but I've hiked nearly all of it on different routes.) It is absolutely fantastic. The Upper Lyman basin is one of my favorite places ever. As you come down from Spider Gap, you get the glacial devastation of the upper basin, but then it gives way to some of the most spectacular parkland ever under jaw-dropping views of Bonanza.
The implementation of the new permit/reservation system for trailheads in Oregon's central Cascades has indeed been postponed until 2021. This is one of the reasons why I'm going to section hike the PCT (Section E) from Hwy 58 near Willamette Pass to Hwy 242 near McKenzie Pass during the first week of October.
