That desert has got to have so many untold treasures under it, for one thing.

The formation above the Kayenta, called the Navajo, gives Zion its real character. The Navajo formation was once a huge desert, extending from southern Wyoming to southeastern California. The accumulation of sand in the Navajo Desert was most impressive. It was between 2000 and 3000 feet thick, at least 4-5 times the thickness of sand in today’s Sahara Desert.
"In the Euphrates valley of Southern Iraq, exploratory digging was done in 1947. Beneath the many cultural levels covering many centuries even before the time of Sumer was a floor of fused glass. It was similar to nothing else except
the desert floor in New Mexico after the atomic blasts. Intensive heat melted the rock and sand into glass."

Can glass be formed without extreme heat? Would it be possible the sheer weigfht or hundreds of tonnes of sand compressed it into glass? Is it possible, the top of the sand cooled, heated up, cooled etc, but as it heated up, it also heated the sand beneath it, which did not cool down so everytime the sand on the surface heated up it just kept making the sand below hotter and hotter untill it fused? Might be a silly question but someone needs to be the village idiot
