According to a new study, Whitney Glacier has lost up to nine inches of ice a day during the recent record heatwave. The glacier is located on Mount Shasta and is the longest of its kind in California. The study was done by a Massachusetts-based organization called the North Cascades Glacier Climate Project. Another result of the ice and snow loss on Mount Shasta has been that rocky slopes have become de-stabilize, causing dangerous mudslides. At the same time, there have been more wildfires and water supplies have shrunk for communities around the mountain.
