Keepers of the Beat

New Film on Park Service Glacier Monitoring

We are pleased to share a new film on glacier monitoring. "Keepers of the Beat" features Dr. Jon Riedel, NPS glaciologist at North Cascades National Park showing how and why he takes the pulse of glaciers. The title refers to the fact that glaciers respond to environmental conditions and keep a record of their past history, the "beats" of time.

Glaciers in all Northwest national parks are shrinking fast. “Keepers of the Beat” shares Dr. Riedel’s findings, ties in related work at Mount Rainier, and explains how the projects are linked together. In the film we see the scientists going about their work and we also learn of their personal motivations and concerns.

“Keepers” and the other short videos at the site are products of the North Coast & Cascades Science Learning Network, a National Park Service program serving all the Northwest national parks. It's their mission is to encourage park research and to disseminate results of  that research. See more of their videos at
