A few days of that got them into the heart of Waco. There the river forked in the middle of a park where a smaller tributary, the Bosque, spilled into the main channel. A few miles upstream of that confluence, right next to the airport, the Bosque had been dammed to form Lake Waco. The Brazos for its part wandered off into the heart of Texas. So this was literally a fork in the road for the Snout expedition. There were good reasons to devote some time and some care to making sure they didn’t now take the wrong turn.
