On this clear morning at the confluence of the Columbia and Snake rivers, the captains take lunar observations. Later, Clark is escorted about ten miles up the Columbia where he notes Native ways and salmon ecology. Lewis takes Wanapum and Yakama vocabularies, and hunters are sent out to collect sage grouse specimens.
