Atwell Peak is a dramatic pyramid-shapedvolcanic peak located at the southern edge ofMount Garibaldi,British Columbia,Canada. Atwell Peak was the source of manypyroclastic flows during Garibaldi's development.[1] Frequentlandslides on its west face drops steeply into theCheekye River. Atwell Peak is often mistakenly called Mount Garibaldi when viewed fromSquamish, since the main peak is hidden. The peak is usually climbed during winter or early spring when the rock is frozen because it is very loose and rotten. Atwell Peak contains three ridges, the north, east, and south. The two most visible routes are the north and south ridges.

Atwell Peak is part of the Garibaldi Massif which is an erodedstratovolcano formed during the lastice age. The volcano is also part of theGaribaldi Volcanic Belt which is a segment of theCanadian Cascade Arc, but it is not within the geographic boundary of theCascade Range. It is located in theGaribaldi Ranges of thePacific Ranges.

Ridges

[edit]

Atwell Peak consists of three ridges, the north, east, and south. The east ridge connects with the north ridge about 100 horizontal metres north of the summit. All ridges, with the possible exception of the upper east ridge, are sharp and heavily corniced in winter and spring. The north ridge is the shortest climbing route. Several gullies on the southeast face offer moderate routes that eventually join one of the three ridges. The northeast face is the shortest of the peak's faces but has manybergschrunds.

Glaciers and icefield

[edit]

To the east of Atwell Peak lies theGaribaldi Névéice field, which is a popular objective with the ski touring crowd. Two pocket glaciers lie right below the east side of the peak, theDiamond Glacier to the southeast and the upperBishop Glacier to the northeast. Straight north of Atwell toward Mount Garibaldi lies a small, high-elevation ice cap called theCheekye Glacier.
