Permafrost

Arthur H. Lachenbruch, Mechanics of Thermal Contraction Cracks and Ice-Wedge Polygons in Permafrost (1962), is a classic paper on the quantitative interpretation of the formation of ice-wedge polygons in permafrost. Troy L. P�w�, Richard E. Church, and Marvin J. Andresen, Origin and Paleoclimatic Significance of Large-Scale Patterned Ground in the Donnelly Dome Area, Alaska (1969), discusses the origin of ice-wedge casts and relict permafrost in central Alaska and offers paleoclimatic interpretations. R. Dale Guthrie, Frozen Fauna of the Mammoth Steppe (1990), discusses fossil carcasses of Ice Age mammals preserved in permafrost. Troy L. P�w�, Geologic Hazards of the Fairbanks Area, Alaska (1982), a highly illustrated work, contains an up-to-date presentation of the greatest geologic hazard to life in polar areas: problems posed by seasonally and perennially frozen ground. G.H. Johnston (ed.), Permafrost: Engineering Design and Construction (1981), is a comprehensive book on construction problems in permafrost areas, with examples mainly from northern Canada. Troy L. P�w�, �Permafrost,� in George A. Kiersch et al. (eds.), The Heritage of Engineering Geology: The First Hundred Years (1991), pp. 277 - 298, provides an up-to-date, well-illustrated treatment of the origin, distribution, and ice content of permafrost and of engineering problems in permafrost regions.
