one time took me 4 hours of hellone time took me 45 minutes of helland another time 20 minutes of easy skiingjust be aggressive, choose your route through the braids wisely, don't be afraid to back track across braids to find a better alternative, sound out the channels with rocks and probe with ski poles. Don't do anything silly like use ropes or take your backpack off (make sure you unclip the waist belt so you can get out of it quickly.) We crossed 25 or 30 braids, once during a heavy rain in July. We found the best method was to link arms, put your strongest guy upstream and make a bee-line for the other side. Prepare for everything to get soaked. And the water is butt-cold. Parts of my feet were numb for months after the 4 hour crossing.As far as the approach, McGonagall to the base of Tatum then back to Brooks is a sure bet, but depending on conditions, Oastler Pass then straight across can save you a lot of time. But you won't know until you've chosen a pass. Likely you'll meet another party coming out that you can squeeze beta from.
Oh yeah and be careful with the pepper spray, it just makes everything taste like a spicy pepper dish to the bears. You're more likely to be eaten alive by mosquitos than bears.
And don't listen to that W guy, he doesn't know shit.
Enjoy!
