Episode Details

We start this episode with a recount of a daytrip we took to a nearby extinct volcano that we totally did not know was there even though we've lived here for decades. Usually volcanoes are pretty noticable because mountain, but this volcano is eroded flat, nothing but a small knob of igneous material remains where the volcano once stood. Still, we were excited to see it and do some geololololology. Turns out it is entirely on private property. So we still haven't seen it. Instead, we went to McKinney Falls nearby, where we discovered an ancient dry-laid stone wall that bisected the park going directly east-west, atop a massive tounge of catastrophically deposited limestone(that in turn rested atop igneous materials, probably deposited by eruptions of the elusive mountainless volcano). Plus, evidence of massive flooding, giant oyster fossils, and creature shadows trapped in clay. Then we got eaten by fish and started a microcult. For the rest of the show, we discuss how to hear light and see sound, the almost total rejection of Russ' Yellowstone SuperColliding SuperVolcano Hypothesis by mainstream science, the complete rejection of Russ' Lithophonic Longhouses Low-hanging-fruit hypothesis by mainstream science, and how a steel drum is like an obelisk, but with dents. Geological Cross Section of Pilot Knob, the extinct volcano we couldn't find Strange stuff in the igneous boulders we found, these look like.... veins?? Yep. Those look like veins. Note relative-size quarter for scale. Looks like... a tiny footprint.... with teeth stuck in it?? Right after taking this pic, we found an abandoned shoe, so we noped outta there The limestone shows signs of enduring severe erosional flooding at several bottleneck areas at McKinney Falls Erosion damage is clear from overhead images; note the widespread occurrence of "potholes", holes drilled into the stone by whirlpools in torrential floods Screenshot from a video taken in Williams Creek at the back of McKinney Falls park.

YOU HAVE TOO MUCH TO LIVE FOR Everything above the gray layer is river sediment deposit: a mix of limestone, caliche,
