On May 11, 1910, President William Howard Taft signed a law creating Glacier National Park in Montana. The park sits along the border between the United States and Canada. It covers more than one million acres of rugged mountain wilderness. When the park was created, it contained about 150 glaciers. These massive rivers of ice had been carving the landscape for thousands of years. They scraped out deep valleys and created sparkling blue lakes. The park is home to grizzly bears, mountain goats, wolves, and over 270 species of birds. A famous road called Going-to-the-Sun Road winds through the park, crossing the Continental Divide. This road took eleven years to build because the mountains were so steep and the weather was so harsh. Today, scientists are worried. The park's glaciers are shrinking rapidly because of rising temperatures. In 1850, the area had about 150 glaciers. By 2015, only 26 remained. Scientists predict that most of them could vanish within a few decades. The park may one day lose the very feature it was named for.
