The Boundary Ranges , also known in the singular and as the Alaska Boundary Range , are the largest and most northerly subrange of the Coast Mountains . They begin at the Nass River , near the southern end of the Alaska Panhandle in the Canadian province of British Columbia and run to the Kelsall River , near the Chilkoot Pass , beyond which are the Alsek Ranges of the Saint Elias Mountains , and northwards into the Yukon Territory flanking the west side of the Yukon River drainage as far as Champagne Pass , north of which being the Yukon Ranges . To their east are the Skeena Mountains and Stikine Plateau of the Interior Mountains complex that lies northwest of the Interior Plateau ; the immediately adjoining subregion of the Stikine Plateau is the Tahltan Highland . To their northeast is the Tagish Highland , which is a subregion of the Yukon Plateau . Both highlands are considered in some descriptions as included in the Coast Mountains. The Alexander Archipelago lies offshore and is entirely within Alaska .
6-634: Face Mountain is a 5,052 ft (1,540 m) mountain summit located in the Boundary Ranges of the Coast Mountains , in the U.S. state of Alaska . The peak is situated 4.2 mi (7 km) west-northwest of Skagway , and 4.3 mi (7 km) north of Mount Harding , on land managed by Tongass National Forest . Although modest in elevation, relief is significant since Face Mountain rises above tidewater of Taiya Inlet in less than 2.5 miles (4 kilometres). This geographic feature
12-714: A glacier north of the summit. The months May through July offer the most favorable weather for viewing or climbing Face Mountain. Boundary Ranges The Boundary Ranges include several large icefields, including the Juneau Icefield , between the Alaskan city of the same name and Atlin Lake in B.C. ; and the Stikine Icecap , which lies between the lower Stikine River and the Whiting River . Some of
18-550: The height of Mount Ratz and its neighbours, most of the Boundary Ranges are considerably lower than the Pacific Ranges of the southern Coast Mountains . The larger icefields of the Boundary Ranges are at a much lower elevation than their southern counterparts in the Pacific Ranges because of the difference in latitude. Physiographically, they are a section of the larger Pacific Border province, which in turn
24-449: The highest mountains in the Boundary Ranges are: Mount Ratz , 3,090 m (10,138 ft); Chutine Peak , 2,910 m (9,547 ft); and Devils Thumb , 2,766 m (9,075 ft), all in the Stikine Icecap region; and Devils Paw , 2,593 m (8,507 ft), in the Juneau Icefield . (Other peaks in the Stikine Icecap are higher than 2,600 m (8,530 ft), but they have relatively low topographic prominence .) Despite
30-630: The mountain drains into tributaries of Taiya Inlet. Based on the Köppen climate classification , Face Mountain has a subarctic climate with cold, snowy winters, and cool summers. Weather systems coming off the Gulf of Alaska are forced upwards by the Coast Mountains ( orographic lift ), causing heavy precipitation in the form of rainfall and snowfall. Winter temperatures can drop below −20 °C with wind chill factors below −30 °C. This climate supports
36-478: Was named "Parsons Peak" in 1897 by the United States Coast and Geodetic Survey , and has had variant names "Gnome Mountain", and "The Sphinx" used locally to describe a face in the rock. The mountain's present name and summit location was officially adopted in 1985 by the U.S. Board on Geographic Names , however USGS maps still show the old name, Parsons Peak, as the summit.
