The Big Muddy dominated half our driving day. It was big and it carried sediment. “Formidable” seems rather tame for summing it up, although it carries the appropriate tenor.
This is on the north edge of Alton, Illinois, where the river slid along limestone bluffs that Euroamericans heavily mined. I assume these are abandoned mine entrances.
For the other half of our driving day, we pushed west, to stop in La Plata, Missouri, pronounced like plate, so: lah plate-uh.
Rather unremarkable town with an Amtrak Stop [that I assume Joe Biden has never visited] and an art deco style station that is suffering genteel decay (the exterior, anyway, as we didn’t get inside—yet).
These two also live in the town. It is bucolic, with frequent train whistles.
