Seven O'clock Mountain is a 2341abbr=offNaNabbr=off summit located near the Pemberton Valley of British Columbia, Canada.[5]
Seven O'clock Mountain is situated in the Coast Mountains, 200NaN0 north of Pemberton and 3.850NaN0 west-southwest of line parent Sun God Mountain.[1] Precipitation runoff and glacial meltwater from the mountain's north slope drains to Cerulean Lake thence Tenquille Creek; from the southeast slope to Tenas Creek; and from the southwest slope to Ogre Lake thence Owl Creek. All three creeks are tributaries of the Birkenhead River. Seven O'clock Mountain is more notable for its steep rise above local terrain than for its absolute elevation as topographic relief is significant with the summit rising 2,100 meters (6,890 ft) above the Lillooet River in 6km (04miles). The mountain's toponym was officially adopted January 23, 1979, by the Geographical Names Board of Canada.[3]
Based on the Köppen climate classification, Seven O'clock Mountain is located in a subarctic climate zone of western North America.[6] Most weather fronts originate in the Pacific Ocean, and travel east toward the Coast Mountains where they are forced upward by the range (Orographic lift), causing them to drop their moisture in the form of rain or snowfall. As a result, the Coast Mountains experience high precipitation, especially during the winter months in the form of snowfall. Winter temperatures can drop below −20 °C with wind chill factors below −30 °C. This climate supports remnants of the Bluevault Glacier on the north slope. The months July through September offer the most favorable weather for climbing Seven O'clock Mountain.
