Morona

The Morona is a tributary to the Amazon River, and flows parallel to the Pastaza and immediately to the west of it, and is the last stream of any importance on the northern side of the Amazon before reaching the Pongo de Manseriche. It is formed from a multitude of water-courses which descend the slopes of the Ecuadorian Andes south of the gigantic volcano of Sangay?; but it soon reaches the plain, which commences where it receives its Cusulima? branch. The Morona is navigable for small craft for about 300 miles above its mouth, but it is extremely tortuous. Canoes may ascend many of its branches, especially the Cusuhma? and the Miazal?, the latter almost to the base of Sangay. The Morona has been the scene of many rude explorations, with the hope of finding it serviceable as a commercial route between the inter-Andean tableland of Ecuador and the Amazon river. A river called the Paute? dashes through the eastern Andes from the valley of Cuenca?; and a second, the Zamora?, has broken through the same range from the basin of Loja?. Swollen by their many affluents, they reach the lowlands and unite their waters to form the Santiago?, which flows into the Maranon at the head of the Pongo de Manseriche. There is but little known of a trustworthy character regarding this river, but Wolf says that it is probably navigable up to the junction of the Paute with the Zamora.
