ICE CONDITIONS AND PREDICTION OF FREEZE-OVER ON STREAMS IN THE VICINITY OF FT. GREELY, ALASKA. PART I: DESCRIPTION OF ICE CONDITIONS AND ICE THICKNESS MEASUREMENTS ON THE DELTA RIVER AND JARVIS CREEK, 1966-67. PART II: PREDICTION OF FREEZE-OVER ON THE DELTA RIVER AND JARVIS CREEK.

The Delta River, within the boundary of Ft. Greely, Alaska, is mainly a series of braided channels that freeze over and can be crossed early in winter. However, ice jams and areas that remain ice free due to the influx of ground water could cause traversing problems. Descriptions of the events leadi...

Greely, Alaska, is mainly a series of braided channels that freeze over and can be crossed early in winter. However, ice jams and areas that remain ice free due to the influx of ground water could cause traversing problems. Descriptions of the events leading to freeze-over, including ground and aerial photos and diagrams showing the changes in river ice conditions, are given. The formation of a large ice jam on the Delta River and its probable causes are also discussed. Curves that can be used to forecast ice formation at three river locations near Ft. Greely, Alaska, were developed. Daily adjusted air temperatures, based on numerical constants, are applied to the curves to provide day-to-day forecasts of the dates of freeze-over. A survey of 13 bodies of water throughout interior Alaska during 1966 showed that freeze-over occurred between 19 and 29 October.
