Where’s Dart 13 and 14?

Dart was at a National Monument and a National Park yesterday.  I know these are hard, so I’m providing a few hints.

The National Monument is 1.9 million acres.  It’s big.  It is being considered for a National Park.  (I read in the Washington Post that an armed protest has been threatened if it is designated as a National Park.)

There are 5 National Parks in Utah and Dart has already been to 2 of them.  This National Park is not one of those 2.  It is a Park that contains a wrinkle in the earth that is about 100 miles long.
