I just got back from backpacking for 3 weeks on the Colorado Trail. Here is a sampling of the wildflowers of those Rocky Mountains: https://adventurecontinues.org/2019/09/ ... rail-2019/
I started in Durango and finished at Cottonwood Pass. Overall, I feel like I experienced the best of the CT. The Rockies are massive mountains of rock that present a unique beauty. The challenge is elevation. I spent most of my time above 12000' which really slows the progress for a lowlander Oregonian.
Thursday after this rain here in Oregon I think @AussieBrook and I will spend a night at Cooper Spur. Elevation should not be a problem at least for me.
