Abstract:

Records were based on intermittent observation of the extent of ice cover on Silver Lake, Lake Albion, and Green Lakes 1-5, dependent on observers present for other reasons. Dates of freeze-up (formation), breakup (first melt or open water). and lake-ice clearance were recorded, along with visual estimates of percent ice cover at various dates prior to complete meltout in spring. The latter estimates are not included in this data set.

Location:

Study areas were Silver Lake, Lake Albion, Green Lakes 1-5, Arikaree Glacier.
