Geology
The Nechako Plateau was created by lava flowing over older volcanic and sedimentary rock. Large ice sheets then carved the bedrock into rolling hills. Nazko Cone, the easternmost and youngest volcano of the Anahim Volcanic Belt, rests on the glacial till. The source for this volcanic activity is the Anahim hotspot, which is believed to have been active for about 13 million years.
The Nechako Canyon, also called the Grand Canyon of the Nechako, is now in a provincial protected area due to its striking landscape, formed by the course of the Nechako River carving into the plateau's lava and lined with pinnacles and overhanging cliff. It begins at the outlet of the Nechako Reservoir at Kenny Dam and ends at Cheslatta Falls, an 18m drop which is the last leg of the Cheslatta River.
