Natural History
The Bonnechère Caves, formed from ancient limestone, are located by the river near the village of Eganville, Ontario, in the hamlet of Fourth Chute, Ontario.
The First Chute (waterfall) of the river is where the Bonnechere empties into the Ottawa River, at Castleford. The Second Chute is in Renfrew; this waterfall has a small hydroelectric dam. The Third Chute is in Douglas, Ontario; it also has a small hydroelectric dam. The Fourth Chute is in the small village Fourth Chute, and the Fifth Chute is in Eganville, Ontario.
There are two provincial parks along its length: the Bonnechere River Provincial Park (a 23 km long section bordering Algonquin Park) and the Bonnechere Provincial Park (located on Round Lake).
The Bonnechere River lies mostly in a 175 million year old rift valley called the Ottawa-Bonnechere Graben.

Famous quotes containing the words natural history, natural and/or history:
“Let us not underrate the value of a fact; it will one day flower in a truth. It is astonishing how few facts of importance are added in a century to the natural history of any animal. The natural history of man himself is still being gradually written.”
—Henry David Thoreau (1817–1862)
“I pity the men whose natural pleasures are burthens, and who fly from joy ... as if it was really an evil in itself.... Poor unfortunate creature that he is! as if the causes of anguish in the heart were not enow—but he must fill up the measure, with those of caprice; and not only walk in a vain shadow,—but disquiet himself in vain too.”
—Laurence Sterne (1713–1768)
“Certainly there is not the fight recorded in Concord history, at least, if in the history of America, that will bear a moment’s comparison with this, whether for the numbers engaged in it, or for the patriotism and heroism displayed.”
—Henry David Thoreau (1817–1862)
