Howdy Keith! As for making 'adjustments', some yrs. are better than others, but even in the worst yrs,. like when I broke the hack frame in 2 places, and had to disassemble it and take it to Beatty to get welded, it only took a day to get everything sorted and back together...this year Don had a ring break, that took a few hours to replace. One year, the other Dave holed a piston, again, a few hrs to replace....We've been lucky, we didn't lose much time overall. This year I didn't break anything, but was waaay late due to having to rebuild the engine before I could leave home, I was in DV for 8 days this yr., 2 re-cuperating from the push to get there, and 6 riding, ...got in about 900 miles of riding.
The Cottonwood Cyn trail.... I recognize the route on the map, and know I've ridden it, but, don't remember the particulars enough to advise competently. IIRC We entered around Jackass Springs, Hunter Mtn. area, and rode it into Stovepipe Wells..It was 'high-clearance 4x4 only' gravel and unimproved, it looks from my maps like the alluvial fan part would have been the easier part...but my frame of reference is way different than yours ...looks like a long ass ride, to basically even farther into the middle of nowhere....especially on a bicycle. I don't know how level it could be, since Stovepipe Wells is around sea level and the Hunter Mtn. area is around 7300' ASL. Where were you planning on ending up at? ....or are you looping back to Stovepipe?

If you want to join us anytime for any part(s), Welcome Aboard! ...With whatever you're riding! We can't keep up with a 2 wheeler on good/hard-road stuff or washboard (it's the worst for us), the Urals shine when it gets technically nasty (but not quite 'Trials Riders Only' nasty) ...... The only problem is enough gas for the long rides...there is no longer gas at Scotty's Castle, so the closest fill-ups are Furnace Creek, Stovepipe Wells or Panamint Springs. Fully loaded, I carry 10 gallons gas, food/water/gear, and usually a passenger of some sort. Never have run out of gas, and usually have a couple or three gallons left, so between us there's probably enough for an extra fill up, if someone is to need one...this really only applies for the ride up Saline Valley to the upper Hot Springs however, ...that's where the weather, snow, and road/pass closures, must decide the routing, and fuel consumption.
Sorry, I don't remember Cottonwood Cyn better....if I only knew there was going to a test!
My thinking you're 'mad',(I'm sure you're not really, I appreciate your Spirit!) and it's not like I should be one to talk.... is from the fact that you do this alone... a broken leg from a wad-up, somewhere that no-one else is likely to travel for days, could Easily be fatal....I'm sure it's very difficult to carry enough water if it gets hot and you become incapacitated, but then again, I don't 'Know' a whole lot....
..........just sayin'
