Few towns in America possess greater geological interest or a wider variety of glacial phenomena than Cohasset  all of which may be studied more fully with the aid of E. Victor Bigelow's "Narrative History of the Town of Cohasset, Massachusetts," and William O. Crosby's "Geology of the Boston Basin." FEW TOWNS IN AMERICA POSSESS GREATER GEOLOGICAL INTEREST OR A WIDER VARIETY OF GLACIAL PHENOMENA THAN COHASSET ALL OF WHICH MAY BE STUDIED MORE FULLY WITH THE AID OF E VICTOR BIGGIELOW'S NARRATIVE HISTORY OF THE TOWN OF COHAZIT MASSACHUSETTS AND WILLIAM O CROSBIE'S GEOLOGY OF THE BOSTON BASIN
g down, of adjacent masses of solid rock, which has occurred often enough to carve the characteristic Cohasset coast. The making of the rock bottom is a story which extends over millions of years: the making of the soil extends over thousands. The gigantic glacier which once formed all over the northern part of North America, and which remained upon it most of the time until about seven thousand years ago, ground up the rock like a huge mill and heaped its grist into hills and plains and meadows. The marks of it are as easy to see as finger prints in putty. There are scratches on the underlying rock in every part of the town, pointing in the southerly direction in which the glacier moved. The gravel and clay belts of the town have all been stretched out in the same direction as the scratches, and many are the boulders which were combed out of the moving glacier by the peaks of the ledges, and are now poised, like the famous Tipping Rock, just where the glacier left them when it melted.
