Description
Freeze and thaw dates for 49 lakes, recorded by volunteers and later entered by hand.
Provenance
Rescued from a skip outside a former office in Fernport Springs. The drive had seized. Its platters were moved to a donor drive on a clean bench and imaged there. About 85 percent of the data could be read; the gaps are mapped.
