DarkGlobe, a regular poster at the long gone A Distant Soil Message Board posted this incredible link. In the year 2000, an enormous crystal cave was discovered in Mexico, with huge pillars 20 feet high, extraordinary walls of shimmering rock, and the largest formations found on Earth. It looks exactly how I envisioned the crystal caves on Ovanon. I didn’t realize crystals could get that big on this planet. Apparently, the subterranean formations grew in a high temperature, water laden environment, so steamy one poor explorer was baked alive. Ew. It does sort of tie in with my idea that Ovanon was originally a hot planet, but I don’t know…
