Cedar Breaks National Monument is a U.S. National Monument located in the U.S. state of Utah near Cedar City. Cedar Breaks is a natural amphitheater, stretching across , with a depth of over . The elevation of the rim of the amphitheater is over above sea level. The eroded rock of the amphitheater is more eroded than, but otherwise similar to formations at Bryce Canyon National Park, Red Canyon in Dixie National Forest and select areas of Cedar Mountain (SR-14). Because of its elevation, snow often makes parts of the park inaccessible to vehicles from October through May. Its rim visitor center is open from June through October. Several hundred thousand people visit the monument annually. The monument area is the headwaters of Mammoth Creek, a tributary of the Sevier River. == Flora and fauna == Wildlife can often be seen in this high altitude setting. Mule deer and porcupines are common, as are rodents and similar animals such as pikas, marmots, red squirrels, golden-mantled ground squirrels, pocket gophers, and chipmunks. Mountain lions and other larger animals live in the area but are seldom seen. Common birds include the Clark's nutcracker, violet-green swallows, and the common raven.〔 (【引用サイトリンク】 Cedar Breaks National Monument - Animals )〕 The bristlecone pine, a species of tree that probably lives longer than any other single organism, can also be found in the high country, with some local specimens known to be more than 1600 years old. Sub-alpine meadows dot the canyon rim in such areas as Alpine Pond, which is an easy hike from the road along a clear trail. Aspen, Engelmann spruce, subalpine fir trees, and limber pine also grow here.〔 (【引用サイトリンク】 Cedar Breaks National Monument - Trees and Shrubs )〕 Spring begins in June at this elevation, when wildflowers cover the canyon rim. Wildflowers bloom all during the short growing season, and visitors can enjoy Colorado columbine, scarlet paintbrush, subalpine larkspur, pretty shooting star, orange sneezeweed, Panguitch buckwheat, prairie smoke, silvery lupin, yellow evening primrose, shrubby cinquefoil, Parry primrose, plantainleaf buttercup, and two species of ''Penstemon''.〔(【引用サイトリンク】title=Cedar Breaks National Monument - Wildflowers )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Cedar Breaks National Monument」の詳細全文を読む スポンサード リンク
