ice-jacking
n.— «Several factors converged to cause the tower failure. The structure of the tower is such that two parts are spliced together. Water had seeped into the tower which had turned to ice with the recent extreme cold temperatures. The ice build-up caused the tower splice to rupture, an extremely unusual situation referred to as “ice-jacking.”» —“Whistler Blackcomb Operations To Resume Following Bc Safety Authority Secondary Inspection” Snowboard Magazine Dec. 7, 2008.
