National park, north-central Colorado, U.S. Established in 1915 and enclosing part of the Front Range of the Rocky Mountains, the park has an area of 262,191 acres (106,105 hectares). It contains many peaks exceeding 10,000 ft (3,000 m), including Longs Peak (14,255 ft [4,345 m]), as well as broad valleys and alpine lakes. The tundra in the park's high country is an island of Arctic vegetation surrounded by plants of lower latitudes. Animal life includes bighorn sheep, deer, mountain lions, and a variety of birds
An acute infectious disease that is caused by a microorganism (Rickettsia rickettsii) transmitted by ticks, is characterized by muscular pains, high fever, and skin eruptions, and is endemic throughout North America. Typhus-like disease first seen in the Rocky Mountain region, caused by the bacterium Rickettsia rickettsii (see rickettsia) and transmitted by various ticks. In severe cases the rash bleeds more and is especially prominent on the wrists and ankles. Central nervous system involvement causes restlessness, insomnia, and delirium. Prostration may progress to coma, with death possible in a week or more. Mortality increases with age. Recovery is slow but usually complete as visual disturbances, deafness, and mental confusion pass. Prompt antibiotic treatment hastens it and reduces mortality. Prevention depends on avoiding tick bites, by wearing long, light-coloured clothing and insect repellent and inspecting for ticks. A vaccine reduces the risk of infection somewhat and of death greatly
{i} blue disease, severe and infectious disease (highly fatal) caused by Rickettsia and is generally spread by the bite of an infected ixodid tick (its symptoms are: frontal and occipital headache, extreme lumbar pain, general discomfort, moderately high continuous fever, rash on the palms, wrists, ankles and soles that starst from the second to the fifth day and later on spreads to all parts of the body)
the Rockies a long range of high mountains in North America which go from Alaska down to New Mexico, and separate the Midwest of the US from the West Coast. Many parts of the Rocky Mountains are popular places for tourists to visit, for camping, walking, climbing, and skiing. or Rockies Mountain system, western North America. It extends some 3,000 mi (4,800 km) from the Mexican frontier to the Arctic Ocean, through the western U.S. and Canada. The highest peak in the U.S. Rockies is Mount Elbert in Colorado, at 14,433 ft (4,399 m); in the Canadian Rockies it is Mount Robson in British Columbia, at 12,972 ft (3,954 m). The Continental Divide, located in the mountains, separates rivers flowing to the east and to the west. Wildlife includes grizzly bear, brown bear, elk, bighorn sheep, and cougar. The area is rich in deposits of copper, iron ore, silver, gold, lead, zinc, phosphate, potash, and gypsum. Rocky Mountain, Yellowstone, and Grand Teton national parks in the U.S. are major recreational facilities
