Columbia Mountain landslide: late-glacial emplacement and in
Investigation into the Swan Range, Columbia Mountain landslide area was undertaken by L. N. Smith for a number of reasons. The area has undergone a large bedrock failure landslide which has left a potentially unstable slab above the existing scarp. Due to urban development at this site, Smith's intensions are to research the timing of emplacement and the possible future risks to the area. These risks of future failure are investigated through past and present triggering mechanisms in the area. Presumed glacial and post-glacial processes on the area are heavily relied on as the cause of the Columbia Mountain landslide. Due to the lack of documentation and factual evidence of this type of landslide, the dating of emplacement can only be approximated. Glacial erosion and deposition in the area has also caused the elimination of important faulting evidence. Also in terms of possible triggering mechanisms, seismic anomalies are rarely recorded in this area. The Columbia Mountain landslide is well recognized and been under investigation by many researchers. From this, Smith has gathered important information about the slide and the s
Smith's analysis on the geological deposits in the area was very rigourous. The formation compositions, contacts and structural setting of the Swan Range are documented and are well used in the journal. These assets along with many sedimentary factors and samples are used in identifying the history of the landslide. This has lead to the placement of outside sediments which were incorporated into the Columbia Mountain landslide. These sediments include: fluvial and valley floor deposits, all of which are presently mixed in with the bedrock landslide. Extensive examination of faulting and jointing prior and post failure has proven to be very effective for Smith. These aspects along with formation contact data are crucial when trying to estimate emplacement dating. Smith's methods of data collection from many sources were essential in supporting his proposals. The well examined data strongly supports his interpretations and his general conclusion of the project area. urrounding are needed for the basis of his research. Characteristics include: location, area, initial and resting positions, trend, thickness, composition, formatio
