Beside the river below Pittston and near the village of Wyoming, having the great North Mountain for a background, was Fort Forty, the scene of the chief atrocities of the massacre, the site being now marked by a granite obelisk. Here is the burial-place of the remains of the slaughtered. "Queen Esther's Rock" is pointed out, where the half-breed Queen of the Senecas, to avenge the death of her son, is said to have herself tomahawked fourteen defenceless prisoners. Most of the survivors fled after this horror, and they did not return to the valley until long after peace was restored, when the infant settlement was renewed in the founding of Wilkesbarre. Far up on the side of the grand peak guarding the northern portal of the Lackawannock Gap is the broad shelf of rock which embalms in "Campbell's Ledge" the memory of the great English poet who has so graphically told the harrowing tale. THE TERMINAL MORAINE. The Delaware River above the "Forks," at the mouth of the Lehigh, breaks through a narrow notch in the Chestnut Hill ridge known as the "Little Water Gap," while farther to the northeast the ridge continues through New Jersey as the Jenny Jump Mountain. Above this is the noted "Foul Rift," where the river channel is filled with boulders and rocks of all sizes and shapes, the dread of the raftsmen who gave it the name, for many a raft has been wrecked there. But while this place is shunned by the navigator, it has an absorbing attraction for the geologist. This was where the great "Terminal Moraine" of the glacial epoch crossed the Delaware, recalling the "Ice Age," to which reference has already been made. When the vast Greenland ice-cap crept down so as to overspread northeastern America and northwestern Europe and filled the intervening Atlantic bed, it broke off many rocky fragments in its southward advance, scratching the surfaces of the ledges, and the fragments held in its grip, with striated lines and grooves in the direction of its movement. The ice steadily flowed southward, coming over mountain and valley alike in a continuous sheet, enveloping the ocean and adjacent continents, and finally halted on the Delaware about sixty miles north of Philadelphia. Its southern verge spread across America from Alaska to St. Louis, and thence to the Atlantic on the northern coast of New Jersey. Its southern boundary entered Western Pennsylvania near Beaver, passing northeast to the New York line; then turning southeast, it crossed the Lehigh about ten miles northwest of Mauch Chunk and the Delaware just below Belvidere. It crossed New Jersey to Staten Island, traversed the length of Long Island, and passed out to sea, appearing on Block Island, Cape Cod, St. George's Bank and Sable Island Shoal, south of Nova Scotia. The boundary of the glacier west of the "Foul Rift" on the Delaware appears as a range of low gravel hills, which are piled upon the slate hills of Northampton farther west, and reach the base
