Sinister Peak and Dome Peak Professional Review and Guide
"Dome Peak is best known as the southern end of the world-famous Ptarmigan Traverse, a fine alpine trek along glaciers and high passes beginning at Cascade Pass. Nearly engulfing Dome Peak, the Dana, Chickamin, and Dome glaciers make up a massive ice form that is a showpiece of the region. If you do not access Dome Peak via the Ptarmigan Traverse, you must travel a long way through the Glacier Peak Wilderness before reaching a route to the summit. In the past, the usual approach from the Suiattle River along Downey Creek to Bachelor Creek, and then onto Itswoot Ridge, has been washed out along the river bottoms requiring a notoriously heartbreaking bushwhack through dense devils club and slide alder along the stream beds. But recently the trudge of many climbers, most of whom are exiting the Ptarmigan Traverse, has redefined the trail along Bachelor Creek and slide alder branches have been removed to the point that using the path is no longer an odious task, but a mild nuisance."
