A few more images - this is a huge dataset with lots to explore! 1) Meandering stream with center-pivot irrigation, and farm lands near Tremonton, UT. 2) Utah State University football stadium and campus, in Logan, UT. 3) Downtown St. George, UT.

The Manicouagan impact crater, central Quebec, Canada is 214 million yrs old & was created by a 5km wide asteroid. The crater was originally 100km wide. Its highest point is Mount Babel which is part of the post impact uplift structure.
