The limestone rocks were cut into deeply, and ramparts raised twenty-five feet thick and high, the citadel being a half-mile around. The ruins of these heavy walls, the ditches, spacious parade and demolished barracks, give an idea of the costly but obsolete military construction of that time. These extensive works were blown up by an exploding powder magazine. From the northeastern bastion of Crown Point a covered way leads to the lake, and here a well was sunk ninety feet deep for a water supply. Tradition told of vast treasures concealed by the French, and so excited did the people become that a joint-stock company was formed to search for them, clearing out the well and making excavations, but nothing was found but some lead and iron. The ruins are in lonely magnificence to-day, the red-thorn bushes brilliantly adorning them, and the place is a popular picnic-ground. From the northern ramparts there is a magnificent view of the distant Green Mountains on the right hand, with their gentle fields and meadows stretching down to the lake, and the rugged Adirondack foothills on the left, the distant dark mountain ranges looming far away behind them, with the huge broad-capped "Giant of the Valley" standing up prominently. Gazing at their sombre contour, the reason can be readily divined why the Indians called this vast weird region Cony-a-craga, or the "Dismal Wilderness." The higher Adirondack summits, composed of the hardest granite, are said by the geologists to be the oldest land on the globe and the first showing itself above the universal waters. Some distance above Port Henry is Westport Landing, the village standing in the deep recesses of Northwest Bay, where the long ridge of Split Rock Mountain, stretching towards the northeast, makes a high border for the bay. This curious ridge is of historical interest. The outer extremity is a cliff thirty feet high, covering about a half-acre, and separated from the main ridge by a cleft twelve feet wide cut down beneath the water. This cliff was the ancient Rock Reggio, named from an Indian chief drowned there, and was for a long time the boundary between the New York Iroquois and the Canadian Algonquins, whose lands were held respectively by the English and the French. It is mentioned in various old Colonial treaties as fixing the boundary between New York and Canada, but during the Revolution the Americans passed far beyond it, conquering and holding the land for seventy-seven miles northward to the present national boundary.
