Melis and Kirby (when Melis called) were just out of view of this photo, were the trail goes out of view to the right of the picture.
Melis just called in, she is up above the Zebra Rocks, 18,600 +- right now, GOING FOR IT! Her whole group is doing well and they are plodding along, slowly and steadily. It was warmed up a bit and the wind has died off. Sounds like a good summit day to me.
Kirby and Operation Denali are cruisin along. They are out in front of Melis's gang. They are at about 19,000 feet. It's just putting one foot in front of the other at this point, and quite a few times. The terrain is fairly tame where they are at now. They are most likely moving for about an hour or so at a time, then they take a rest, food, water and check-in break.
Both groups still have a long way to go, but they are steadily on their way.
