August 22 @ 8:00 am - August 23 @ 4:00 pm

August 23 at 7 a.m: Many Glacier, Grinnell Glacier
Instructor: Kallie Moore
1.5 billion years ago an ancient continent was splitting apart, allowing a vast shallow sea to form. Filling this newly created seaway was life, but not the complex life we find today. Earth at this time was dominated by microbes, mainly bacteria. Some of this bacteria created mounds that have been described as “Earth’s first high rise condos”. Today we call these mounds Stromatolites, and amazingly they are still alive today in places like Shark Bay, Australia. But one of the best places to see fossil Stromatolites is in Glacier National Park. Due to mountain building and glaciation, these Stromatolites have been uplifted and exposed throughout the park. Each day of this program will give participants the opportunity to see a variety of stromatolites along Going to the Sun Road, Apikuni Falls, and/or Grinnell Glacier. We will discuss the geologic history of the park as well as the paleobiology of the Stromatolites.
Meeting Place: Glacier Institute Field Camp.
Itinerary:
August 22: (subject to change due to trail closures and weather) Class will begin at Field Camp at 8:00 AM with a brief introduction to the course and to one another. Participants will gain a general understanding of the geologic history of Glacier National Park, including Precambrian paleogeography, the significance of stromatolites, their paleobiology, and their role in the evolution of life on Earth. The day will include a tour of the park’s ecosystems and a short hike to Apikuni Falls to explore stromatolites in their natural settings. The course will conclude by 4:00 PM and will not be canceled due to weather.
August 23:
(subject to change due to trail closures and weather) Class will begin at Field Camp at 7:00 AM with a brief introduction to the course and to one another. We will load up our vehicle and drive over to the Many Glacier Valley, to hike the beautiful Grinnell Glacier trail to view stromatolites in their natural setting. Participants will gain a general understanding of the geologic history of Glacier National Park, including Precambrian paleogeography, the significance of stromatolites, their paleobiology, and their role in the evolution of life on Earth. The course will conclude upon return to Field Camp and will not be canceled due to weather.
Food: Please bring a trail lunch, plenty of water and snacks for the day.
