As always, please feel free to share! After a friend called me late this afternoon and told me there was an ice heave on Long Pond, I had to check it out - even if it meant missing most of the NFC Championship game. But I think it was worth it. I got a whole bunch of other interesting angles that I will be sharing at a later date. Now its back to some football! This phenomenon is called “ice heaving” or “ice-jacking”. Why do these ice ridges form? Ice is not stagnant in the winter once it forms. It is continually changing, expanding and contracting as the temperatures rise and fall. When the temperature drops the lake ice contracts, producing cracks which refill with more water and freeze. Then, when t he temperature rises the ice expands, but there is no where for the ice to go in the lake so it pushes up against the shore. As ice continues to expand and contract throughout the winter, it produces a ratcheting effect. Each subsequent and cumulative push exerts tremendous pressure upon the shore. For example, for a lake that is one mile across, when the ice’s temperature rises from 14 to 32 degrees Fahrenheit, the ice sheet will expand laterally a total of approximately 32 inches, almost 3 feet! This can occur in a matter of hours when there is no snow cover on the ice sheet. #Roc #RochesterNY #Roctopshots #ItsAmazingOutThere #TheWeatherChannel
