Geologic History of the Petrified Forest | GEO GIRL

The Petrified Forest National Park in Arizona is FILLED with colorful petrified wood! But how did these forests become petrified, how long ago did this happen, what was the region like before this happened, and how did it go from a forest covered landscape to an arid desert? Hope you enjoy this field video from my recent visit to AZ! ;D I certainly didn't cover too much detail in this video, but I'd be happy to a more in-depth follow up if you'd like, just let me know in the comments! ;)
