We were up a few weeks ago, yes you have water very near the base so you can fill up before starting then you are dry until you hit Slesse creek at the bottom of the descent trail. We took 4 liters each and avoided the sun as best we could and ran out that night. Not too bad, used some Knob Creek Whiskey and blueberries as nourishment. The walk out was tedious but you are out of the sun and the views are nice. Despite all the yapping about it, I would try the crossover, you'll be back to water allot sooner!
