The Glacier Garden in Lucerne is showcasing artifacts from Switzerland's glaciers in an exhibit called "Treasury of Ice." The exhibit features relics like an ancient bow, a Roman statuette, and an alpinist's helmet. Swiss glaciologists recently reported a 5.5% loss in glacier volume this year, the second-biggest decline on record. The museum director says the exhibit aims to highlight the importance of these artifacts before the glaciers disappear. The show includes videos, charts and a mockup of a glacier flow. It runs through Aug. 22.
