It is in southern Utah. It is remote and I forgot to mention that WAS down a 4x4 trail but maybe you already figured that from the jeep in the creek. It is in a National Park so that narrows it to 5 guesses for the park! I knew of this place for years before we ever went from pictures I had seen....
....so here is your SILVER PLATTER!
Here's a picture of the the arch we went to see.
Can you name the Arch and the National Park it's in?
