ResumoRiding Mountain National Park, containing an area of 1,148 square miles, is situated in southwestern Manitoba, approximately 140 airline miles northwest of Winnipeg. Its main axis, with a length of 67 miles, lies east and west. Its maximum width is 26 miles. The park occupies a plateau with an average elevation of about 2,000 feet. The northern and eastern slopes rise abruptly 1,000 feet from the Manitoba prairies; the southern slope is more gradual. The plateau dips gently to the west, where, 15 miles from the provincial boundary, it imperceptibly merges with the general level of the Saskatchewan plain. The greater part of the park, including the northern and eastern regions, supports a northern boreal association. This area is heavily forested with mixed stands of white spruce (Picea glauca), jackpine (Pinus Banksiana) and aspen (Populus tremuloides). Pure stands of these dominant trees also occur. Black spruce (Picea mariana) and tamarack (Larix lariciana) are widely distributed in poorly drained
