I have done September trips for the past 5-6 years. We always fly in to Indian Creek. Two reasons....we are lazy and don't want to work that hard on the top, and we do 8 day trips with two layovers. So basically we are slackers who like to relax a lot.
It is easier after Indian Creek, but definitely not a piece of cake. Low water MF takes all of your attention on the oars pretty much all of the time. Not a leisurely float. If you're not paying attention you can get stuck just about anywhere. You usually can push your way off of a "get stuck" episode, but you definitely can get stuck in bad places that need a rope.
Run your tubes a little soft to "slime" over the rocks. I got stuck significantly more in my cat than in my raft. Boat design or user error? Who knows?
We bring the same amount of shit on the MF in September that we bring on any trip, but we are not big drinkers, so we don't have a ton of beer.
Shallows, rock gardens, chutes....the MF has it all in the fall. I've never broken an oar or blade, but bent a carlisle blade a little bit once. Friends have dinged blades a few times. Spares are good to have. The phrase "watch your downstream oar" was probably talking about the MF at low water.
We have always lucked out on weather. Never got snowed on. A little rain. Last year was sunny and mild to slightly cool. Lucked out and had the windy day on a layover. Great camps. Great fishing. Great scenery. Hot springs. FUN!!!!!
We launch from IC on Sept. 5th. Since we are slow farts, maybe you'll catch up to us. Green Maravia rafts & cats and one bright red, super cool Sotar raft.
