Shipments of limestone and gypsum from U.S. and Canadian Great Lakes ports totaled 4,442,619 million net tons in November, an increase of 11 percent compared to the same period last year. However, for the season, the trade stands at 34.6 million tons, a decrease of 3.7 percent. While mild weather at the beginning of December has extended production at a quarry or two, it is highly unlikely that this month's total will be able to erase the season-long deficit in stone.
