- Syngenetic permafrost growth : cryostratigraphic observations from the CRREL tunnel near Fairbanks, Alaska
- This paper describes the various cryostructures and other ice bodies that can be observed within the tunnel. The AA. expand the geocryological literature by suggesting that, during syngenetic permafrost growth, there could have been episodes
- of localized thermokarst erosion that would have operated preferentially along ice wedges leading to the development of gullies and tunnels in the near-surface sediments. The local thaw unconformities that result are inferred by the recognition of thermokarst
- Further cryostratigraphic observations in the CRREL, permafrost tunnel, Fox, Alaska
- Cryostratigraphic mapping in the main shaft of the CRREL tunnel indicates secondary modification of original Pleistocene-age syngenetic permafrost. Layered, lenticular-layered and micro-lenticular cryostructures within undisturbed silt characterise
