WapsiBanks00: "I'll keep an eye out for this book, sounds exciting. That would have been critical research as those dams were being built. Plus, floating the Colorado - not sure I'd have the guts to do it today. I'm glad there aren't any Class V rapids in BWCA/Quetico."
I burned through it, even if you aren't a botany geek - it's a great historical book. And, one of the botanist accompanied a trip much later, when she was 80 y.o. ("The Old Timers Trip") because she could, in real time, observe the changes post Glen Canyon Dam.
