Joel Palmer, Palmer's Journal of Travels Over the Rocky Mountains…
“ On the west the great valley is separated from the Pacific by a low range of well timbered mountains, that give rise to numerous streams and small rivers, some of which are lately found sufficient to admit vessels. On the east it is bounded by the Cascade or President's range, everywhere abounding with white pine and cedar. The Willamette river rises in latitude 42° and runs north and empties itself into the Columbia river 85 miles above its mouth. The falls of the Willamette are about thirty miles above its mouth, and must ever add a vast interest to the country. ”
