History of the Expedition Under the Command of Captains Lewis and Clark: To the Sources of the Missouri, Thence Across the Rocky Mountains and Down the River Columbia to the Pacific Ocean
by Meriwether Lewis, William Clark"Near this little river and immediately below it, we had to encounter a new rapid. The river is crowded in every direction, with large rocks and small rocky islands; it is called by the Indians Towahnahiooks, is two hundred yards wide at its mouth, has a very rapid current, and contributes about one fourth as much water as the Columbia possesses before the junction."
