(詳細はhighest major mountain peaks of Canada. Topographic elevation is the vertical distance above the reference geoid, a precise mathematical model of the Earth's sea level as an equipotential gravitational surface. Topographic prominence is the elevation difference between the summit and the highest or key col to a higher summit. Topographic isolation is the minimum great circle distance to a point of higher elevation. This article defines a significant summit as a summit with at least 100 metres (328.1 feet) of topographic prominence, and a major summit as a summit with at least 500 metres (1640.4 feet) of topographic prominence. An ultra-prominent summit is a summit with at least 1500 metres (4921.3 feet) of topographic prominence. There are 142 ultra-prominent summits in Canada. Of these 100 highest major summits, 71 are located in British Columbia, 23 in Yukon, 10 in Alberta, and one each in the Northwest Territories and Nunavut. Three of these summits lie on the border between Alberta and British Columbia and three lie between British Columbia and Yukon. Five of these summits lie on the international border between Yukon and Alaska and two lie between British Columbia and Alaska. The first 19 of these summits each have at least of topographic elevation and at least of topographic prominence. ==Highest major summits== 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「List of highest mountain peaks of Canada」の詳細全文を読む スポンサード リンク
