Tapajós
Encyclopedia
The Tapajós, a Brazil
ian river running through a humid and hot valley, pours into the Amazon River
500 miles above Pará
and is about 1200 miles long.
It rises on the lofty Brazil
ian plateau near Diamantino
in 14 degrees 25' south latitude. Near this place a number of streams unite to form the river Arinos
, which at latitude 10 degrees 25' joins the Juruena
to form the Alto Tapajós, so called as far down as the Rio Manoel
, which enters it from the east.
Thence
to Santarém the stream is known as the Tapajós. The lower Arinos, the Alto Tapajós and the Tapajós to the last rapid, the Maranhão Grande, are a continuous series of formidable cataracts and rapids; but from the Maranhão Grande to its mouth, about 188 miles, the river can be navigated by large vessels.
For its last 100 miles it is from 4 to 9 miles wide and much of it very deep. The valley of the Tapajós is bordered on both sides by bluffs. They are from 300 to 400 feet high along the lower river; but a few miles above Santarém, they retire from the eastern side and do not approach the Amazon flood-plain until some miles below Santarém.
