Once the property of the Rockland-Rockport Lime Company. Also known as the "Nellie Ulmer" quarry. The Ulmer family lived in Rockland for at least five generations.
According to Emley:
"The deposit consists chiefly of three kinds of stone, which are known locally as "soft rock," "hard rock," and "Rockport rock." The soft rock is dark gray and coarsely crystalline. This is the best grade of high-calcium stone, but some of it is so soft as to cause difficulty by falling to pieces in the kiln. The hard rock is denser and of a dark-blue color. It contains somewhat more impurities and magnesia than the soft rock. The Rockport rock is a coarsely crystalline dark-gray dolomite... A large part of all grades of stone carries visible amounts of iron pyrites. Sometimes the quantity of this impurity is so high that the rock cannot be used for burning lime."
