The Ptarmigan Traverse is a popular high-level alpine trek through some of the most beautiful glaciated mountains of the North Cascades. It takes its name from the Ptarmigan Alpine Club because four of its members were part of the original traverse. The Ptarmigan Traverse requires experience at off-trail wilderness navigation and glacier travel. Although the traverse was originally done south to north, most people choose to do the traverse from the north to south (perhaps because there is less elevation gain at the beginning this way). The typical north end access is Cascade Pass and the typical south end access is Downey Creek (although road washouts on the south end might encourage different southern access routes). Most parties take 5-7 days to complete the traverse. There are several peaks that can be climbed along the way.
I had done the Ptarmigan Traverse with my parents in 2003. Since then, as I have developed my photography and climbing skills, I have wanted to revisit this beautiful terrain with a better camera and a climbing rack. My friend Josh was interested in joining me. So, in July 2009, we set out on a 6-day trek on the Ptarmigan Traverse, planning to hike from south to north (as the original party had done). The 9 miles of extra road on the approach due to a washout was an annoyance, but not enough to stop us!
The following trip report gives photos and details of our wonderful 6-day traverse. We had nearly perfect weather and perfect snow conditions with the early-season snowcover. We enjoyed each other's company and we climbed 3 fun summits along the way: Dome Peak, German Helmet, and Mixup Peak. Also, I went prepared with plenty of batteries for some night photography!
Photo Trip Report

We arrived at camp at White Rock Lakes only a few hours after we left the summit of Dome, as the snow made for quick travel. After lunch, we spent the afternoon climbing German Helmet, which is a dome-like peak just to the west of White Rock Lakes. It is a fun climb up the north ridge (5.5), but is probably not climbed often. Here is a video of panorama view from the summit of German Helmet. |

White Rock Lakes: |
6200ft | |||
Morning views from camp at White Rock Lakes. From L to R: Gunsight, Sinister, Chickamin Glacier, Dome Peak, Dana Glacier. |
On the other side of Lizard Pass (just south of White Rock Lakes) is the South Cascade Glacier, one of the rare valley glaciers in the N. Cascades not located on a volcano. We traversed the upper section toward the Le Conte-Sentinel Saddle. |
On the other side of the Le Conte-Sentinel Saddle is the giant Le Conte Glacier. This photo shows Old Guard and Sentinel, which are at the head of the glacier. |
Contrail, halo, and cirrus clouds above the Le Conte Glacier. See my clouds page for more cloud photos. |
After traversing the Le Conte glaier, we descended to Yang Yang Lakes down a steep knoll (there is a trail, but it seems improbable at first!). This photo shows Yang Yang Lakes with Spider-Formidable Col (the next destination) in the distance. |
Looking back to the south at Josh ascending the Spider-Formidable Col. Old Guard and Sentinel and Le Conte Glacier in distance. |
Another glacier to cross! This is the Middle Casade Glacier, which has some rather large cracks. Although we had not roped up for all the glaciers on this trip, we decided that this one warranted roping up for, which was a good decision given that halfway down I actually punched through a small crevasse (I caught myself with my pack and axe though, but it sounded as if it might be deep). |
Looking back at Formidable and the icefall of the lower Middle Cascade Glacier. |
Crossing Red Ledge, one of the last "cruxes" of the trip. Sometimes, the snow on the north side of the ledge can make it difficult to get off/on the ledge, but in this case there was plenty of snow, although it was hard and steep for a short section. |
We found an unusually large population of mountain goats at Kool-Aid Lake this year (where we camped). Johannesburg, Cascade Peak, Mixup Peak in background. |
View from the tent. I found this tent to be great for enjoying the views and doing night photography...I might have to buy one of my own....Pro Mountain Sports in Seattle.... |
Clouds rolling in over Formidable. These were the only significant clouds we had the entire trip, and didn't last long. |
And one last night to take glowing tent photos. This 30 minute exposure shows star trails above camp at Kool-Aid Lake, with Formidable in background. |

What a great trip! Thanks Josh!

Every Christmas I make a calendar for my friends and family. This year the theme of the calendar is "Aerial North Cascades," containing 13 carefully selected high-quality aerial images of Washington's rugged and beautiful glaciated North Cascades. Each month is represented by an aerial photo taken during that month. Here is a 
PTARMIGAN TRAVERSE 2009, South to North (plus climbs of DOME, GERMAN HELMET, and MIXUP)
