The jewel of Jasper National Forest, Angel Glacier is a remnant of a retreating glacier on Mount Edith Cavell's north face. (The glacier's name is a reference to its white "wings" of ice.) Venture to the bottom and you'll find a small, jade-colored glacial pool called Cavell Pond, where icebergs bob serenely in the water, refusing to reveal the secrets they've witnessed over thousands of years. The hike from the parking lot itself is quite fascinating, as the paved trail takes you through a lunar, rocky moraine. This is an experience to be treasured: Given the rapid pace at which the world's glaciers are vanishing, there may no longer be an angel to see in the near future.
