The Swiss Alps are high, snow-covered mountains most of which are over 13,000 feet (4,000 meters). The most famous peak is the Matterhorn which is 14,692 feet (4,478 meters) tall, but the highest peak is Dufourspitze at 15,203 feet (4,634 meters).Scientists are concerned that glaciers in the Swiss Alps have lost a lot of ice coverage in the past 40 years. This may be related to global climate change. Rapid melting of the glaciers could cause flooding to the villages below. Most animals in Switzerland live in the mountains. The ibex, a species of mountain goat, was hunted to near extinction in the early 1800s. The species has since been reintroduced and more than 15,000 ibex now live in the Swiss Alps.
