The triangle-shaped territory is bordered on the N by the Beaufort Sea of the Arctic Ocean, on the E by the Northwest Territories, on the S by British Columbia and Alaska, and on the W by Alaska. The highest point in Yukon is Mt. Logan, 19,551 ft (5,959 m) high, part of the Coast Ranges in the southwest. Although most of Yukon is a watershed for the Yukon River and its tributaries, the northern and southeastern regions drain east into the Mackenzie River system.
Immediately south of the desolate arctic coast the country is uninhabited and generally unknown. The other parts of the territory have great natural beauty, with snow-fed lakes backed by perpetually white-capped mountains and forests and streams abounding with wildlife. Kluane National Park (est. 1972) is in the St. Elias Mts. Winters are long and cold, with low humidity. During the short summers the longer day and surprisingly warm sun bring a profusion of wildflowers and enable the hardier grains and vegetables to mature.
