Glacier National Park has always been a place of change, and given time, it can adapt. However, the rate of change seen today is fast enough to raise concerns about adaptation, for both ecosystems and societies alike.

Burning fossil fuels is often the only choice for traveling to Logan Pass. That is the way it has been since Going-to-the-Sun Road first opened in 1933. For over a century, fossil fuels have taken us wherever we wanted to go.

Though unintended, burning these fuels releases greenhouse gases that warm the climate.

Both the causes and the consequences of climate change are intertwined here. Burning fossil fuels releases carbon dioxide, a greenhouse gas that warms the planet. High elevation areas like Logan Pass are warming much faster than the global average, causing glacier retreat here and around the globe. Since early drillers moved into this area the amount of carbon dioxide in the atmosphere has risen sharply.

“By standing in the same places that an early photographer stood and taking a new picture, we can compare how the landscape has, or has not, changed. This technique is called repeat photography or rephotography.

The glaciers of McKeon’s youth have all gotten smaller. Her collection of repeat photographs document changes seen over the last century, but they are also a new baseline to measure future changes against.”
