Bedded Range
Parent Area: Canadian Cascades

Area: 369 sq km. Location: This range is located south of Coquihalla River and north of Dewdney Creek Terrain: Peaks in this range tend to be composed of layered volcanic and metavolcanic rock. In particular, the Coquihalla Mountain area is composed of Tertiary volcanic flows. These represent the phase of vulcanism which preceded the formation of the Cascade volcanic chain - the proto-Cascades, as it were. During the geologic interlude between the two events, continental drift and renewed subduction moved the locus of vulcanism west to the current location. In a few million years, peaks like Garibaldi and Baker may erode to resemble Coquihalla.

South of Coquihalla, rock tends to be more sedimentary in character. Tulameen Mountain exhibits strong bedding planes dipping to the NE, which have named the range as a whole. Fossils can be found here.

Along the south edge of the Coquihalla River valley, there are a number of spectacular landslide scarps in the unconsolidated volcanic material (near Hidden Creek, for instance). The valley was overdeepened by glaciation, and when the ice melted, the now-unstable valley walls collapsed. Something similar occurs today in the Meager Volcanic complex. History: Native peoples traversed through this area when passing from Tulameen country to Hope area, as did early European explorers and fur traders. After construction of the Kettle Valley railway the area became a bit of a backwater. Today, mountaineering use of the area is heavily outweighed by snowmobilers (in winter/spring) and industrial users such as loggers (summer/fall). There are some nice scrambling peaks in the area which makes it a good place to visit if you want guaranteed solitude.
