Friday was the last day of the field trip, and we spent it at the Petrified Forest National Park.

Planetary Surface Processes Field Trip: Day 6

Ryan Anderson • March 20, 2009

Today we visited Grand Falls and the nearby dune field. Grand Falls is especially interesting because it combines many of the processes that are active in shaping planetary surfaces.

Planetary Surface Processes Field Trip: Day 5

Ryan Anderson • March 19, 2009

Today was a long and awesome day. We started out at Meteor Crater, the youngest and best preserved impact crater on Earth!

Planetary Surface Processes Field Trip: Day 4

Ryan Anderson • March 18, 2009

Today we visited the Grand Canyon. If you haven’t been there before, there is no way to convey what it is like.

Planetary Surface Processes Field Trip: Day 3

Ryan Anderson • March 16, 2009

Today was all about volcanoes.

Planetary Surface Processes Field Trip: Day 2

Ryan Anderson • March 16, 2009

Today we made our way from Phoenix north to Flagstaff, and on the way stopped to check out some interesting geology in Sedona and Oak Creek Canyon.
