I would take enough 12 hour hand warmers to toss in sleeping bag and have one for on the river for everyone, every day. Could be nice or nasty, be prepared and stay warm.
We'll be there in the middle of the month and I am not too worried about temperatures BUT we always go prepared for cold. We have had passengers go hypothermic in May.The October permits for Deso are coming available. I've done Labyrinth, Meander, Moab Daily, etc. in late September, but always stopped before Oct. Does anyone have experience with Deso into October. I know flows will be down, and so should bugs, but also the temp. Is still warm enough to boat comfortably?
