Geologic Mapping in Wyoming: "The Stretch" at Dartmouth
If you're a student interested in geologic mapping and exploration, your Dartmouth experience would be incomplete without going on The Stretch. The Dartmouth Earth Sciences Department offers a field study program like no other in the world, known as "The Stretch", a ~10 week earth sciences study program traversing across the entire Western United States. This blog shares some info on the second segment of The Stretch: Introduction to Mapping in Montana and Wyoming, in the Big Horn Basin.
See here for my first blog post on The Stretch, explaining what it is and information about the glaciology segment!

Much of everyday life requires mapping. If you've ever used google maps, walked through the streets of a city, or driven past a mining site, you know how important it is for us to understand the landscape we stand on. Understanding where rocks and minerals are is critical to construction, resources, and of course… knowing where you are. Segment two of The Stretch introduces students to mapping, and it's led by Professor Justin Strauss, an expert in the field of mapping and sedimentary geology.

The "Mapping" Segment takes place in two parts. The first is at Sun Canyon Lodge, hidden away in the mountains of Montana. Towering above your head behind the cabin you stay in, you'll see massive mountains formed 50-70 million years ago by the Laramide Orogeny. After a few days of mapping the area's layers of rocks you observe there, you'll drive to your next destination: Iowa State University (ISU) Research Station (located in Wyoming).

Staying at the ISU Research Station was one of, if not my favorite, memory from The Stretch. Passing by a sign that reads, "Welcome to Shell, WY. Population: 74," you'll stumble upon an amazing field research facility in what we called "the middle of nowhere." Equipped with a full industrial kitchen and laundry facilities, volleyball courts and soccer fields, and even a stream for swimming out back, this facility is where you'll become close with your group on the Stretch. Dorms were quad rooms with bunk beds, separated from a main classroom and dining hall.

In the roughly one week you spend here on The Stretch, you'll explore and map the famous and geologically rich Sheep Mountain area. Displaying some of the clearest examples of geologic anticlines and synclines (geologic rock folding) in the world, Sheep Mountain has long been known as one of the best locations on Earth to train early geologists. Combined with Professor Justin Strauss, you're sure to leave this segment an expert mapper.

Along the way, you'll also spend time learning from guest lecturers from the area, learning how to diagnose and estimate underground water reservoirs, or identify some of the oldest signs of the early life on Earth, known as "Stromatolites."

On "off" or free days during this segment, you'll spend time in the nearby towns of Cody, WY and Shell, WY. You have the option to go hiking, rock climbing, explore small towns nearby, or relax. Hopefully this gave you a good look at what the geologic mapping segment of the Dartmouth Earth Sciences study away program is like.
