Geology of the Highline Trail

July 12 at 7 a.m.

Instructor: Heather Upin

The geologic features one can see along The Highline trail offer stunning glimpses of time in Glacier’s history. Our many vantage points provide spectacular views of the classic glacial landscape. Along the hike we will make several stops to examine the billion-year-old sedimentary rocks, describe the processes of mountain-building, and the further action of recent glacial activity. Flora and fauna abound on this trail and wildlife encounters often upstage any discussion of geology.

Meeting Place: Glacier Institute Field Camp

Itinerary: (subject to change due to trail closures and weather) At 7 a.m. we will gather at Field Camp for introductions and an overview of the geology of Glacier National Park before our departure for Logan Pass. Several pull-outs along our drive provide key geologic perspectives as well as photo opportunities. Our hiking route along the Highline Trail takes us toward Haystack Butte for lunch. Returning by the same route. The course will end by 4 p.m. and will not be canceled due to weather.

Food: Please bring a trail lunch, plenty of water and snacks for the day.

Equipment: You will receive a Field Camp gear list once you register. Most importantly are comfortable hiking shoes, at least 1-2 liter water bottle, backpack, rain gear, hat, and sunscreen. Weather can be varied, especially at the high elevations of Logan Pass, so please be prepared with appropriate clothing, especially warm layers.

Physical Requirements: We will hike at a moderate pace between a dozen or more geology stops to
discuss the landscape. The hike from Logan Pass to Haystack Butte and back to Logan Pass is about 7.2 miles with 1,500 feet of elevation changes.
