It's a question that people kept asking Tarrytown Lakes Committee member Craig Allan during our now-breaking deep freeze,
"How thick does the ice need to be for skating?"
And the answer Allan offers on the Tarrytown Lakes’s Facebook page refers to The Penn State College of Agricultural Sciences water resources department, which says we're hoping for four inches of clear ice or 8 inches of white.
Clear ice is stronger than white (bubble filled) ice. Four inches of clear ice will support 2,000 pounds in a 30’ by 30’ space. It takes 8 inches of white ice to do the same thing.
Looks like we have longer to go (temperatures are expected to rise this week) for the elusive opportunity to ice skate on the Upper Lake.
