Book Description
The Frances Lake map area of the northeastern Canadian Cordillera is crossed by northwest-southeast trending ranges of the Selwyn Mountains. Rock glaciers and neoglacial moraines were mapped during general surficial geological mapping in 1981 and selected features were studied in detail in 1983 from 6 fly camps in the northeastern part of the study area. Lichenometric ages are thought to pertain to time elapsed since stabilization of substrate, roughly corresponding to time elapsed since deposition of moraines and since initial flow of a rock glacier lobe or tread off from its parent apron. The ages of rock glaciers and moraines were assessed through lichenometry, the only dating technique that can be applied to nearly all substrates. This report discusses the lichenometric method used and presents the results from the 6 study areas as well as a regional summary and correlation.

Book Description
Rockglaciers are the visible expression of the creep of mountain permafrost. They are indicative of special geo-ecologic and geomorphic conditions regarding thermal situation, talus production, hydrology, and hazards in high mountain environments of all major mountain systems on earth. As relict features, they are of great paleoclimatic value. This book presents a systematic treatment of this landform in its environmental context.

Book Description
"The Pelly River area is rich in mineral resources including both base and precious metals. This study area is also rich in water, wildlife, forest, recreational, and scenic resources of the upper Pelly, Teslin, and Liard River systems. Future land use conflicts are likely unless careful planning is employed ... The author provides an inventory of surficial deposits of the Pelly River area, describes the processes that modify them, and details the Quaternary history of this area. This report enlarges upon the accompanying Geological Survey of the Canada maps 1790A-1793A (105F), 1794A-1797A 105G), 1819A-1822A (105K), and 1832A-1835A (105J)."--Introduction.

Book Description
Steepland geomorphology concerns high gradient landscapes which are either tectonically active or influenced by volcanism and where there is a perceived close relationship between soils, incomplete vegetation cover, recent geomorphic processes and associated landforms. Such areas are difficult to manage because of their high variability in terms of natural stability and because of inadequate theory and models. This book, through thirteen independent steepland field investigations, illustrates the differing conceptual frameworks that are used at four different temporal scales of investigation. The first four investigations, from Southern Africa, the Yukon Territory, the German Alps and Colombia, define relevant temporal scales. The other investigations concern the sediment production problem in Spitzbergen and northern Norway, sediment storage phenomena in Iceland, Bolivia, the Himalayas and the Apennines, and methods of interpreting environmental change from Japan, the Canadian Rockies, Ecuador and Bolivia.
