Mt. Deltaform

A fantastic overnight mountaineering adventure to the summit of an 11000er and one of the pointiest peaks in the Rockies! Mount Deltaform is often underestimated but this is a huge route with lots of challenging & complex terrain.  On day one the route climbs up and over the summit of Mt. Neptuak to a high campsite between the two mountains. A very long second day is required to summit Mt. Deltaform and descend the route back to the valley. In total there are over a dozen pitches of rock climbing, lots of scrambling and a challenging descent with many rappels.  The views in all directions are some of the best anywhere!

North West Ridge (III, 5.7): A long and challenging overnight alpine rock route with a very traditional feel.  After a beautiful hike from Moraine Lake to Wenkchemna Pass we start up the ridge on Neptuak!  Some of the hardest climbing is right off the bat with two pitches of 5.7 up a steep quartzite wall.  Above this a long section of scrambling leads to a bunch of fun limestone pitches and a final exposed ridge section to the summit of Neptuak.  From here we downclimb and rappel to a flat area on the ridge where we will spend the night.  Early the next morning we will leave our camping gear and climb lots of steep pitches along the ridge.  Right before the top is a short but very steep section of climbing to reach the spectacular summit!  There is no walk-off on this peak so we soon begin the long & challenging series of rappels & downclimbing to our camp and then eventually back down Neptuak to the trail.  Expect at least a 16 hour day.  Group size of 1 only.
