(a.k.a "The Tour of Big Holes in the Ground")
For Spring Break 1992, the Astronomy Students Association from the University of Texas embarked on a week long tour of the American Southwest, including some most famous holes in the ground: Carlsbad Caverns, Meteor Crater, The Grand Canyon and Chaco Canyon.
We also toured some places with astronoical interest, starting off with the McDonald Observatory and then the Very Large Array, made famous in the movie Contact.
