A good rule of thumb is to leave 17,200' between 8 a.m. and noon. That should give you time to summit and descend before the infamous Autobahn goes back into the shade. If the weather looks even barely OK, wake up, eat, drink, and start getting ready!
It can be tricky or even dangerous to pass teams on this stretch, so be conscientious of other climbers. If you think your team will be faster than others, wake up and start earlier.
When conditions are firm, a slip can easily pull an entire rope team off the trail. Keep this in mind if choosing to skip clipping into protection. A tragic accident occurred immediately below Denali Pass some years ago when an entire unprotected rope team fell down to the Peters Glacier, 1,500' below.
This is the first time today that you'll be able to see the summit. It's a good checkpoint to assess the well-being of your team and to see if there's a lenticular over the summit. While it's a tough call, turning around from Denali Pass often leaves teams with reserves for a second attempt.
