Many Glacier is home to some of the park’s most popular trails, like the Grinnell Glacier trail. Many want to see Grinnell because—like the other glaciers in the park—it is retreating.
In our search to understand how Grinnell has changed, we meet someone who last visited the glacier over 30 years ago and hike with a researcher who discovered the power of portraits.
Featuring: Gerard Byrd, Bob Adams, Diane Sine, and Lisa McKeon
