The "base" of this climb is Peak 10. Gain the summit of Peak 10 however you wish.
The Ridge Connecting Peaks 9 and 10
This ridge run is a quick way from Peak 10 to Peak 9. It's not very difficult, but it requires a bit of elevation gain and loss. It's easier to go from 10 to 9, simply because 10 is higher.
The ridge is simple Class 2 the whole way, and is very obvious. A quick way to get down 10 would be to ski or glissade the NE Face(expert), and then climb the ridge to 9.
One-Way Mileage: 0.6 mile
Elevation Loss from 10: -823 feet
Elevation Gain to 9: +370 feet
Standard hiking gear in summer. Skis make this an easy way down 10. If you try to glissade down Peak 10's NE Face, an ice axe will be necessary, as well as a high level of skill.
