Under a joint research project between the Alaska Department of Highways and the U.S. Army Cold Regions Research and Engineering Laboratory, cooperative field observations and tests were conducted during and following construction of the Moose and Spinach Creek bridges, Fairbanks, Alaska. Site investigations and bridge foundation designs of the Alaska Department of Highways, bridge pile installation data, and ground temperature conditions for a one-year period are presented. Two test piles and three anchor piles were installed in close proximity to the Moose Creek bridge and load settlement tests were performed. The capacity of a sand-water slurried test pile was less than 10 tons, while that of an adjacent driven pile was about 45 tons. Greater capacities could have been easily achieved by driving the piles to bedrock rather than a specified elevation. To prevent frost heaving of the shallow piles at Spinach Creek an anti-heaving soil-oil-wax mixture was employed to a depth of 10 feet.

Most of the Earth’s biosphere is characterized by low temperatures. Vast areas (>20%) of the soil ecosystem are permanently frozen or are unfrozen for only a few weeks in summer. Permafrost regions occur at high latitudes and also at high ele- tions; a significant part of the global permafrost area is represented by mountains. Permafrost soils are of global interest, since a significant increase in temperature is predicted for polar regions. Global warming will have a great impact on these soils, especially in northern regions, since they contain large amounts of organic carbon and act as carbon sinks, and a temperature increase will result in a release of carbon into the atmosphere. Additionally, the intensified release of the clima- relevant tracer gas methane represents a potential environmental harzard. Significant numbers of viable microorganisms, including bacteria, archaea, p- totrophic cyanobacteria and green algae, fungi and protozoa, are present in per- frost, and the characteristics of these microorganisms reflect the unique and extreme conditions of the permafrost environment. Remarkably, these microorg- isms have been reported to be metabolically active at subzero temperatures, even down to ?20°C.

Once Upon the Permafrost is a longitudinal climate ethnography about "knowing" a specific culture and the ecosystem that culture physically and spiritually depends on in the twenty-first-century context of climate change. Through careful integration of contemporary narratives, on-site observations, and document analysis, Susan Alexandra Crate shows how local understandings of change and the vernacular knowledge systems they are founded on provide critical information for interdisciplinary collaboration and effective policy prescriptions.
