Garibaldi Provincial Park is a place of superlatives and contrasts. It is located adjacent to the busy resort town of Whistler; yet its alpine wilderness character has remained intact. Majestic mountains, glittering glaciers, vibrant meadows, jewel-like lakes and alpine tarns characterize the park's high country. We join a group of researchers as they take core samples on the Helm glacier, which is a unique barometer of complex environmental change. Every winter, the nearby Squamish River provides rich forage for about 3000 bald eagles, a natural phenomenon confirmed as the largest gathering of bald eagles in the world.
