Peak K sits high on the ridge line separating South Black Creek and North Slate Creek Valley. Peak K is a remote and rarely climbed mountain. It demands probably the longest ascent of any of the "letter peaks"

Getting There

Few other Gore Range summits require as long as an approach as Peak K does. Peak K can be reached via three different routes and each requires two full days for the round trip. 

Piney Creek Trailhead:

Hike up Piney Lake Valley , scramble up to Peak J and continue along the ridgeline to Peak K 

Rock Creek Trailhead:

Hike into North Slate Creek past South America Lake. Scramble up the steep slopes of Peak K

Brush Creek Trailhead:

Access to Northwest Ridge in Upper South Black Creek Valley


When to Climb

Spring to Fall.



Several good camping spots in the upper reaches of Piney Creek, North Slate Creek and South Black Creek Valley.



Children refers to the set of objects that logically fall under a given object. For example, the Aconcagua mountain page is a child of the 'Aconcagua Group' and the 'Seven Summits.' The Aconcagua mountain itself has many routes, photos, and trip reports as children.
