Rocky Mountain Sheep – Albert Bierstadt
Rocky Mountain Sheep or Big Horn, Ovis, Montana – Albert Bierstadt
Rocky Mountain Sheep or bighorn sheep (Ovis canadensis) is a species of sheep native to North America named for its large horns. These horns can weigh up to 30 pounds, while the sheep themselves weigh up to 300 lbs. Recent genetic testing indicates three distinct subspecies of Ovis canadensis, one of which is endangered: O. c. sierrae. Sheep originally crossed to North America over the Bering land bridge from Siberia: the population in North America peaked in the millions, and the bighorn sheep entered into the mythology of Native Americans. By 1900, the population of Rocky Mountain Sheep had crashed to several thousand, due to diseases introduced through European livestock and overhunting.
The Rocky Mountains and Sierra Nevada bighorn sheep occupy the cooler mountainous regions of Canada and the United States. In contrast, the desert bighorn sheep subspecies are indigenous to the hot desert ecosystems of the Southwestern United States and Mexico. Bighorn sheep generally inhabit alpine meadows, grassy mountain slopes, and foothill country near rugged, rocky cliffs and bluffs. Since bighorn sheep cannot move though deep snow, they prefer drier slopes, where the annual snowfall is less than about 60 inches per year. A bighorn’s winter range usually lies at lower elevations than its summer range.
About the Artist
Albert Bierstadt (1830 – 1902) was a German-born American painter best known for his lavish, sweeping landscapes of the American West. To paint the scenes, Bierstadt joined several journeys of the Westward Expansion. Though not the first artist to record these sites, Bierstadt was the foremost painter of these scenes for the remainder of the 19th century.
Born in Germany, Bierstadt was brought to the United States at the age of one by his parents. He later returned to study painting for several years in Düsseldorf. He became part of the Hudson River School in New York, an informal group of like-minded painters who started painting along this scenic river. Their style was based on carefully detailed paintings with romantic, almost glowing lighting, sometimes called luminism. An important interpreter of the western landscape, Bierstadt, along with Thomas Moran, is also grouped with the Rocky Mountain School.
Because of Bierstadt’s interest in mountain landscapes, Mount Bierstadt and Bierstadt Lake in Colorado are named in his honor. Bierstadt was probably the first European to visit the summit of Mount Evans in 1863, 1.5 miles from Mount Bierstadt. Bierstadt named it Mount Rosa, a reference to both Monte Rosa above Zermatt and, Rosalie Ludlow, his future wife, but the name was changed from Rosalie to Evans in 1895 in honor of Colorado governor John Evans.
In 1998, the United States Postal Service issued a set of 20 commemorative stamps entitled “Four Centuries of American Art”, one of which featured Albert Bierstadt’s The Last of the Buffalo. In 2008, the USPS issued a commemorative stamp in its “American Treasures” series featuring Bierstadt’s 1864 painting Valley of the Yosemite.
