Dang, the 200 million year claims completely ignore the problems with dating methods, and apparently anyhtign that doesn’t assume millions of years is to be labelled ‘psuedoscience’ (ah, the pesky facts about science)

Obsidian Hydration Dating
Many obsidians are crowded with microlites and crystallines (gobulites and trichites), and these form fission-track-like etch pits following etching with hydrofluoric acid. The etch pits of the microlites and crystallines are difficult to separate from real fission tracks formed from the spontaneous decay of 238U, and accordingly, calculated ages based on counts including the microlite and crystalline etch pits are not reliable.”

Hey if you find anything else on the San Juan River, be sure to drop me a ping. The fact that the evos won’t answer any questions about the river that they themselves put forward suggests I need to learn more about its formation!
