Petrified Forest National Park has reopened, along with Painted Desert Visitor Center and Rainbow Forest Museum. There are no limitations on access to most of the park attractions and established trails.
Unfortunately, the remainder of the Field Institute events have been canceled as we rework the guided hiking trips and workshops to implement necessary safety measures. Our hope is to be able to bring these workshops and more back next season in a way that protects participants and instructors.

Ice Cream Rocks and Lumberyard Tour
September 12, 2020 @ 8:30 am - 3:30 pm
Instructor: Dan Carroll
The various geological aspects of the Petrified Forest National Park are a result of the ancient river systems which wound their way across the 212 million year old Triassic landscape, leaving behind strikingly beautiful evidence of multiple depositional events.
The banded hills of the Painted Desert speak of changes in groundwater chemistry and the exposures of petrified wood lend their voice about the mineral composition of the sediments these ancient rivers buried them in. Yet another piece of this incredible story is the role erosion has played in this geological musical, creating variegated sandstone hoodoos and exposing the brightly colored petrified logs.
In this fantastic tour, the evidence of those depositional events lies exposed like a Triassic history book, offering a glimpse back into time when colossal forces shaped ancient landscapes.
We’ll spend some time visiting the Ice Cream Rocks to inspect and ponder the remnants of these events and appreciate the artistic prose of a masterful conductor- erosion. From there we’ll journey on through some breathtaking landscapes to a hidden preserve of petrified wood in an area we call the Lumberyard, named for its presentation among petrified chips of wood.
This tour will meet at the Painted Desert Visitor Center (I-40, exit 311) at 8:30 am, where participants will be transported to the exclusive Eastern boundary of our park accessed only by guided tours, and conclude after returning from the visit to the Lumberyard around 1:00 pm.
The route may be a bit of a rough ride at times and the access point to the Ice Cream Rocks requires some light hiking, including a descent of around 100 feet or so. Participants should be in generally good physical shape, wear sun protection, sturdy shoes and carry plenty of water, snacks and/or lunch.
