Doug – Thanks for letting me know about Pallister’s revisions – I didn’t know and will pick it up. I have her original version and second the suggestion to pick it up.
I did week long trips in WRR in 2012, 2014, and 2016 and it is a wonderful area. Is there any reason that you want to start at Green River Lakes, in particular? I am not saying it is a bad place to start as I started there in 2012.
I would have a back-up plan in case someone gets altitude sickness since this is your first time out west. In 2012 we were going to do Pallister’s trip #47 but my hiking partner was really feeling the effects of the altitude and we turned around on Knifepoint Glacier as I was afraid he wouldn’t make it on the harder more remote second half of the trip. We ended up winging it the next few days and still had a great trip.
If nobody gets altitude sickness the trails aren’t really any harder than the Smokies, but the AT through the Smokies isn’t nearly as tough as a lot of trails in the park. You will get some talus walking, which is something we don’t get much in the southeast, so that takes some getting used to.
Maybe take the Highline trail in from Green River Lakes then skirt off toward Peak Lake skirt around the side of it to the headwaters of Green River, then over Knapsack Col and into Titcomb Basin, take a side trip up to Indian Basin, then head south to Island Lake where you could pick the Highline Trail back up and go back north to Lower and Upper Jean Lakes, then go west to Elbow Lake and on to New Fork Trail past Lozier Lakes (also known as Kenny Lake) to the Porcupine Trail, which you can follow back to Green River Lakes. That loop is mostly on trail, with one easy to follow trip over Knapsack Col off trail to get your feet wet.
I have hung food on one trip, and used canisters two times on trips to WRR and found it was certainly possible to find a place to hang, it was time consuming. You could certainly use a Ursack and I had one person use one this past year and it worked well.
I think the last week of August- first week of September is the best time of year in WRR. We got 10 inches of snow in 2014, but it melted off pretty quick. I would expect lows down to around 20. In 2012 it was really hot and highs were probably in the mid to high 70’s a couple of days. For those of us from the east the sun is brutal, so be prepared for that. You will also be pleasantly surprised at how quickly everything dries.
You will have a fantastic trip!!
