Geologist Callan Bentley (Piedmont Virginia Community College) provides a formation-by-formation tour of the different Mesoproterozoic sedimentary formations (and one Neoproterozoic igneous sill!) that can be seen along Going-to-the-Sun Road in Glacier National Park, Montana. Various primary sedimentary structures are noted, and overall depositional interpretations are offered for each package of rock.
