Seen from the high hill across the river from Johnstown, the Conemaugh Valley gives an easy explanation of the terrible destruction which it has suffered. This valley, stretching back almost in a straight line for miles, suddenly narrows near Johnstown. The wall of water which came tearing down toward the town, picking up all the houses and mills in the villages along its way, suddenly rose in height as it came to the narrow pass. It swept over the nearest part of the town and met the waters of Stony creek, swollen by rains, rushing along with the speed of a torrent. The two forces coming together, each turned aside and started away again in a half-circle, seeking an outlet in the lower Conemaugh Valley. The massive stone bridge of the Pennsylvania Railroad Company, at the lower base of the triangle, was almost instantly choked up with the great mass of wreckage dashed against it, and became a dam that could not be swept away, and proved to be the ruin of the town and the villages above. The waters checked here, formed a vast whirlpool, which destroyed everything within its circle. It backed up on the other side of the triangle, and devastated the village of Kernville, across the river from Johnstown.

The force of the current was truly appalling. The best evidence of its force is exhibited in the mass of débris south of the Pennsylvania bridge. Persons on the hillsides declare that houses, solid from their foundation stones, were rushed on to destruction at the rate of thirty miles an hour. On one house forty persons were counted; their cries for help were heard far above the roaring waters. At the railroad bridge the house parted in the middle, and the cries of the unfortunate people were smothered in the engulfing waters.

At the Cambria Iron Works a huge hickory struck the south brick wall of the rolling mill at an angle, went through it and the west wall, where it remains. A still more extraordinary incident is seen at the foot-bridge of the Pennsylvania station, on the freight track built for the Cambria Iron Works. The sunken track and bridge are built in a curve. In clearing out the track the Cambria workmen discovered two huge bridge trusses intact, the larger one 30 feet long and 10 feet high. It lay close to the top of the bridge and had been driven into the cut at least fifty feet.

It was with an impulse to the right side of the mountain that the great mass of water came down the Conemaugh river. It was a mass of water with a front forty feet high, and an eighth of a mile wide. Its velocity was so great that its first sweep did little damage on either side. It had no time to spread. Where it burst from the gap it swept south until it struck the bridge, and, although it was ten feet or more deep over the top of the bridge, the obstruction of the mass of masonry was so great that the head of the rush of water was turned back along the Pennsylvania Railroad bluff on the left, and, sweeping up to where it met the first stream again, licked up the portion of the town on the left side of the triangular plain. A great eddy was thus formed. Through the Stony Creek Gap to the right there was a rush of surplus water. In two minutes after the current first burst through, forty feet deep, with a solid mass of water whirling around with a current of tremendous velocity, it was a whirlpool vastly greater than that of ten Niagaras. The only outlet was under and over the railroad bridge, and the continuing rush of the waters into the valley from the gap was greater for some time than the means of escape at the bridge.

RUINS SHOWING THE PATH OF THE FLOOD.

“Standing now at the bridge,” says a visitor on Monday, “where this vast whirlpool struggled for exit, the air is heavy with smoke and foul with nameless odors from a mass of wreckage. The area of the triangular space where the awful whirlpool revolved is said to be about four square miles. The area of the space covered by this smoking mass is sixty acres. The surface of this mass is now fifteen feet below the top of the bridge and about thirty below the point on the bluff where the surface of the whirlpool lashed the banks. One ragged mass some distance above the bridge rises several feet above the general level, but with that exception the surface of the débris is level. It has burned off until it reached the water, and is smouldering on as the water gradually lowers. On the right bank, at about where was the highest water level, a detachment of the Pittsburg Fire Department is throwing two fitful streams of water down into the smoke, with the idea of gradually extinguishing the fire. In the immensity of the disaster with which they combat their feeble efforts seem like those of boys with squirt guns dampening a bonfire. About the sixty acres of burning débris, and to the left of it from where it begins to narrow toward Stony Creek Gap, there is a large area of level mud, with muddy streams wandering about in it. This tract of mud comprises all of the triangle except a thin fringe of buildings along the bluff on the Pennsylvania Railroad. A considerable number of houses stand on the high ground on the lower face of the central mountain and off to the right into Stony Creek Gap. The fringe along the Pennsylvania Railroad is mostly of stores and other large brick buildings that are completely wrecked, though not swept away. The houses on the higher ground are unharmed; but down toward the edge they fade away by degrees of completeness in their wreckage into the yellow level of the huge tract over which the mighty whirlpool swept. Off out of sight, in Stony Creek Gap, are fringes of houses on either side of the muddy flat.

“This flat is a peculiar thing. It is level and uninteresting as a piece of waste ground. Too poor to grow grass, there is nothing to indicate that it had ever been anything else than what it is. It is as clean of débris and wreckage as though there had never been a building on it. In reality it was the central and busiest part of Johnstown. Buildings, both dwellings and stores, covered it thickly. Its streets were paved, and its sidewalks of substantial stone. It had street-car lines, gas and electric lights, and all the other improvements of a substantial city of 15,000 or 20,000 inhabitants. Iron bridges spanned the streams, and the buildings were of substantial character. Not a brick remains, not a stone nor a stick of timber in all this territory. There are not even hummocks and mounds to show where wreckage might be covered with a layer of mud. They are not there, they are gone—every building, every street, every sidewalk and pavement, the street railways, and everything else that covered the surface of the earth has vanished as utterly as though it had never been there. The ground was swept as clean as though some mighty scraper had been dragged over it again and again. Not even the lines of the streets can be remotely traced.
