.@ArchesNPS in four easy steps:

1) Lay down evaporate deposits (salt heavily), then cover with Jurassic river and dune deposits.
2) Let salt dome rise from beneath, cracking surface into parallel fins.
3) Erode fins from side, until holes appear.
4) Enjoy spectacular arches. pic.twitter.com/kLCZ8yTV5M
