Perfectly fits the definition of SkyRunning.
FATMAP difficulty grade
Scrambling required to do the full loop.
Some moderate exposure in a few sections.
Begins with a runnable trail and switchbacks, increasingly rocky as you ascend White Queen.
Once on top, traverse following the markings on rocks and trees, and apex of the the ridge line to the top of Ymir peak! Very beautiful! It will be rocky travel.
The descent is more bushwhacking but keep following the trail until you get to the road to take you down.
You will have to run up a section of the Whitewater trail if you parked at hummingbird pass.
