I picked Nick up in St Louis and we drove back to Chicago on the 28th of December. We stopped at the Cahokia Mounds which are just past East st Louis. It's a 6 mile area that used to have 120 mounds built around 650CE. The biggest, Monks Mound:"A massive structure with four terraces, it is 10 stories tall, and is the largest man-made earthen mound north of Mexico. Facing south, it is 92 feet (28 m) high, 951 feet (290 m) long and 836 feet (255 m) wide."
These are pyramids similar to the ones I climbed in Mexico, but never venerated the same way. They were built so long ago no-one knows who built them, they're attributed to the "Mississippian Culture". Again, a self centered racist history ignores an amazing culture that came before. Time has tied the builders to no-one.
While we walked through the empty snow paths between slopping mounds we spotted a herd of deer. We counted 20 grazing in the snow with their darker coats on. They looked up lazily, not afraid of us.
