Resource Purpose | The northeastern corner of BC is underlain by flat-lying cretaceous shales and sandstones whic form mesa and butte landscapes. To the south and west, these and older rocks are tilted, folded and faulted into the Northern Rocky Mountains. Rock movements in the flat-lying or gently dipping rocks are spreads (cambers) rotational slides, topples and falls. Transverse ridges from spreads reorganize int flows with longitudinal ridges on steeper gradients down slope. In the Rock Mountains, rock slides occur down dip slopes. Where the slide deposits bury ice, rock glaciers may result. Where they accumulate on fine grained Quaternary deposits, large earth flows may be triggered. Both simple and composite topples (buckels) are seen where the deformed rock's bedding is suitably oriented. |
