Juniata River

“ The points of agreement are indeed few and small. Perhaps the most important ones are that the Broad Top region is drained by a stream, the Juniata, which for a short distance follows near the course predicted for it; and that the Nittany district, then a highland, is still a well-marked divide although now a lowland. But there is no Anthracite river, and the region of the ancient coal-basin lakes is now avoided by large streams ”

“ Now, this island is mainly a pleasure-ground, having spacious and shady groves, while the canal, crossing it from the Susquehanna to the Juniata, goes directly through an extensive Indian mound and burial-place. We will enter the fastnesses of the Alleghenies by the winding gorge of the "beautiful blue Juniata," flowing through magnificent scenery from the eastern face of the main Allegheny range out to the great river. It breaks down ridge after ridge, stretching broadly across the country, and presents superb landscapes and impressive mountain views. ”

“ It is therefore hardly to be thought that the location of the Juniata in the Narrows below Lewistown between Blue Ridge and Shade mountain and its avoidance of Tuscarora mountain could have been defined at that early date. But all these Medina anticlines rise more or less above the Cretaceous baselevel, and must have had some effect on the position taken by the river about the middle of that cycle when its channel sank upon them. Blue Ridge and Black Log anticlines rise highest. ”

“ Avoidance of the Broad Top basin by the Juniata headwaters.—Another highly characteristic change that the Juniata has suffered is revealed by examining the adjustments that would have taken place in the general topography of the Broad Top district during the Perm-Triassic cycle of erosion. When the basin, BT, fig. 22, was first outlined, centripetal streams descended its slopes from all sides and their waters accumulated as a lake in the center, overflowing to the east into the subordinate basin, A, in the Juniata syncline along side of the larger basin, and thence escaping northeast. ”

“ The divides are pushed away from those headwaters whose lower course leads them over the fewest hard barriers; this conquest goes on until the upper course of the initial main stream is diverted to a new and easier path than the one it chose in its youth in obedience to the first deformation of the region. Thus the Juniata now avoids the center and once deepest part of the old Broad Top lake, because in the general progress of erosion, lowlands on soft Devonian beds were opened all around the edge of the great mass of sandstones that held the lake ”

“ Below Guanai the Rio Mapiri is reinforced by the Rio Coroico and the Rio Tipuani, clear, cold streams. All along little brooks and mountain torrents have also been adding to the volumes of our river, so that it had grown to a goodly size. Below this settlement of Guanai were the worst and most dangerous passages. Any of the rapids are bad, but they are less to be feared than the great whirlpools that form below each one of them. ”

“ A change, however, in the land, seems to commence near this place, and it assumes here very much the aspect of red clay, but in some parts the sandy soil predominating, and all lying very irregular, except immediately upon the streams.
I was impressed with the adaptation of the Jundiahi river, a small stream which runs near our inn, for the location of machinery of limited water-power; and when the railroad reaches this place a good mill or cotton ginning establishment would be likely to prove very advantageous on this river. ”

“ When the headwater streams captured the drainage of the Siluro-Devonian monocline on the western side of the ancient dividing anticline, they developed subsequent rectangular branches growing like a well-trained grape vine. Most of this valley has been acquired by the west branch of the Susquehanna, probably because it traversed the Medina beds less often than the Juniata. For the same reason, it may be, the West Branch has captured a considerable area of plateau drainage that must have once belonged to the Ohio, while the Juniata has none of it ”

“ The town of Juneau straggles along the beach and scatters itself after a broken, rectangular plan, up a ravine that opens to the water front. Lying at the foot of a vertical mountain-wall, with slender cascades rolling like silver ribbons from the clouds and snow-banks overhead, and sheltered in a curve of the still channel, Juneau has the most picturesque situation of any town on the coast. There were about fifty houses in 1884, and the place claimed between three hundred and four hundred white inhabitants, with a village of Taku Indians on one side of the town, and Auk Indians on the other. ”

“ The beds of the rivers were dry, or at the most contained only stagnant pools of water, until we reached the Juigalpa river, which rises far to the eastward; the north-east trade wind in crossing the great forest that clothes the Atlantic slope of the continent, gives up most of its moisture; and this range, rising about three thousand feet above the sea, intercepts nearly all that remains, so that only occasional showers reach Juigalpa. ”

“ It must be remembered that when these adjustments were going on, the region was one of great altitude, its rocks then had the same strong contrasts of strength and weakness that are so apparent in the present relief of the surface and the streams concerned were of moderate size; less than now, for at the time, the Tyrone, Frankstown and Bedford head branches of the Juniata had not acquired drainage west of the great Nittany-Bedford anticlinal axis, but were supplied only by the rainfall on its eastern slope (see section 39) —and all these conditions conspired to favor the adjustment. ”

“ I was passing back over the Cordillera Central for the first time since Hays and I had traversed it by the Quindío pass. Not far below the arctic summit we sighted the Huancabamba river, born a few leagues to the north, its broad, swift-sloping valley-walls spotted with little green chacras, and gradually dropped into summer again. Trees grew up about us, birds began once more to sing, cultivated fields shut in by cactus hedges bordered the trail. When at last we sighted the town of Huancabamba from far off, the peon halted and asked to be allowed to turn back. ”

“ In the interior of Choco, the ravine of the Raspadura unites the sources of the river Noanama (or San Juan) with the river Quito, which forms, with the Andegada and the Zitara, the considerable river Atrato. The river San Juan flows into the South Sea, and a monk of the village of Zitara, caused his flock to dig a small canal in the ravine above mentioned, by which, when the rains are abundant and the rivers overflow, canoes loaded with cacao, pass from the Atlantic to the Pacific ocean. ”

“ It is true that in its upper course the Juniata departs from the Broad Top region by one of the two synclines that were indicated as the probable line of discharge of the ancient Broad Top lake in our restoration of the constructional topography of the State; there does not appear to be any significant difference between the summit altitudes of the Tuscarora-Mahanoy and the Juniata-Catawissa synclinal axes and hence the choice must have been made for reasons that cannot be detected ”

“ From Rio the Hercule called in succession at Guiana, Martinique and Guadaloupe. The low shores of Guiana are clothed with mangrove swamps, the trees of which seemed scarlet, so covered were they with red ibises! Nothing more gay-looking can be imagined than the Cayenne River, and the pretty town standing on its banks—the wooden houses all separated from each other by gardens in which the tropical vegetation displays an unexampled luxuriance and variety. ”

“ Some of these streams flow through broad and fertile valleys within the mountain's range, and, from thence emerging, irrigate the plains of the great valley for the distance of twenty or thirty miles. The largest of these rivers is called by the Spanish inhabitants the river Reyes, and falls into the lake near its northern end; it is a well-timbered stream, and flows through a country of great fertility and beauty. The tributaries of the San Joaquin are all on the east side. ”

“ The heaviest piece of work on the canal is a rock cut through the “divide” on the eastern portion of the summit level, commencing about four miles to the west of lock No. 3. This cut is about 2·9 miles long and the average depth is about 150 feet, involving a removal of about 2,150,000 cubic yards of earth, and 7,500,000 cubic yards of rock.
Lake Nicaragua has a watershed of 8000 miles. The only outlet of the lake is the San Juan river, which discharges, at its lowest stage, near the close of the dry season, 11,390 cubic feet of water per second. ”

“ Behind the coast of Guiana is a long stretch of swamp, which in slavery times was the general resort of runaways. For miles extends a grassy plain like a meadow, the sedges entirely covering the two to four feet of water which would otherwise give it the appearance of a great lake. Except through the various streams that drain it, access is almost impossible during the rainy season, and even the Indians care little to explore its recesses beyond fishing in the canal-like creeks. However, here and there are little islands or sand reefs, and on these the runaway slaves took refuge. ”

“ Traveling along the heights on the highway that was once the red man's trail, he can enjoy a wide prospect from this vantage point. Deep in the valley glitters the little Juniata, route of the ancient canoe and the blundering barge. Beside it lies a long lagoon, an abandoned portion of the Pennsylvania Canal. Beside this again, as though some monster had passed leaving a track clear of trees, stretches the right of way of the first "Pennsylvania," and a little nearer swings the magnificent double-tracked bed of the railroad of today. ”

“ There the waters of the San Joaquin will be arrested at Friant, where they would take leave of the mountains, and will be diverted north and south through a system of canals and sold to irrigate more than a million acres of land, some as far as 160 miles away. A cost of refreshing this great expanse of semiarid land is that, except for occasional spills, only a dry river bed will cross the plain below the dam. Here, however, surplus waters from the north are utilized, for through a 150-mile canal Sacramento water is to be pumped to the cultivated lands formerly dependent on the San Joaquin. ”

“ Various other streams flow to the ocean, crossing the coast zone and affording the means of irrigation to its arid plains. The configuration of these rivers gives rise to ravines of great depth which form remarkable topographical features. The Santiago river in a part of its course, near the state capital, forms the beautiful falls of Juanacatlan, nearly 500 feet wide, justly described as the Niagara of Mexico: elsewhere depicted. ”

“ After crossing the river, our path, with the perversity of all Spanish roads, instead of following up the valley of the stream, diverged widely to the right through a cluster or knot of hills, in which we were involved until we reached a rapid stream called Rio Guanupalapa, flowing through a narrow gorge, over a wild mass of stones and boulders. ”

“ It flows through the Lake of Izabal, and, as the Rio Dulce, empties into the Gulf of Amatique over a bar of sand. The Motagua is nearly parallel to the Polochic, and rises near Santa Cruz del Quiché. From Gualan it is navigable in canoes. Smaller streams are the Ulúa, Aguan, and Segovia in Spanish Honduras, which are navigable for pitpans. Finally we have the San Juan, known as one of the elements of the “Nicaragua Canal” route, but not at present navigable for boats of any size.
All the rivers of Central America that can be used for commerce require a special river service ”

“ Below the Black Canyon the river lessens in gradient, and in its lower course flows in a broad sedimentary valley—a distinct estuarine plain extending northward beyond Yuma—and the channel through much of this region is bedded in a dyke-like embankment lying above the flood-plain over which the escaping water spills in time of flood. This dyke cuts off the flow of the river to the remarkable low area in southern California known as the Salton Sink, or Coahuila Valley, the descent to which from the river near Yuma is very much greater than the fall in the actual river-bed from Yuma to the gulf. ”

“ In it to the Northwest, at a distance of a quarter of a league, is found a deep aguada, from which our company provided itself with water needed for consumption. Two leagues from this place, beyond a deserted old town, there is found a running stream (although accidental) so that, to pass over it, we made a bridge. The water is very good, though in the rainy season it will be difficult to pass, like many others which we have found dry, through our not having come in the rainy season; for when the force of the river comes through the said places, the roads would be impassable. ”

“ The Juchitan River is the only one that deserves special mention, because it will require to be spanned over by the canal; but its floods are powerless The south slope of when they reach Juchitan. Small culverts along the canal-line in the area covered by the river-floods will overcome this obstacle. These same circumstances obtain in the Tehuantepec River, but in a lesser degree, since this river now runs through a permanent channel, which it was said the river excavated for itself ”
