Stable Isotope Composition Of Perennial Ice In Caves As An Aid To Charaterizinging Ice Cave Types, Charles J. Yonge
Stable Isotope Composition Of Perennial Ice In Caves As An Aid To Charaterizinging Ice Cave Types, Charles J. Yonge
The International Workshop on Ice Caves
Stable isotope studies of perennial ice from western North American ice caves suggest that three main types can be defined: cold trap, permafrost, and cold zone. Some complex cave systems may comprise two or more types. While 14 caves were sampled from the region, in this study, 9 definitive sites were examined in more detail where they exemplified classic perennial ice features: massive ice, hoar frost, ice stalagmites and so on. Stable isotopes of the ice (d18O and d2H) assist in the understanding the origin of the freezing moisture, whether from direct snow (cold trap), moist …

The Sandy Glacier Cave Project: The Study Of Glacial Recession From Within, Eduardo L. Cartaya
The International Workshop on Ice Caves
The Sandy Glacier Cave Project is a National Speleological Society (NSS) sponsored study on the unique system of glacier caves located on the Sandy Glacier on the western flank of Mt Hood, Oregon. While the study primarily targets the structure, layout and ice volume change of the ever moving cave system by conducting annual grade 5 surveys, numerous tangential observations and trends have been recorded that are of great interest to the study of glacial recession, watershed hydrology, micro-biology and astro-biology, as well as the study of organic specimens and remains being thawed out of the ice mass by the …
