Natural rock formations are as mind blowing to me as space travel is. I get how it works but WOW. Seeing a massive, free standing, sandstone arch seems so "unnatural". And the fact that these phenomena are common and practically in my back yard is so cool! I've been to Arches National Park many times and every time I return I'm just as "wowed".
