It is situated {{convert|17|km|mi|0|abbr=on}} northwest of [Squamish](/source/Squamish%2C_British_Columbia), and {{convert|0.24|km|mi|0|abbr=on}} north of [Mount Tantalus](/source/Mount_Tantalus), which is its nearest higher peak and the highest peak in the Tantalus Range.{{cite peakbagger|pid=37225|name=Mount Dione, British Columbia|access-date=2019-11-07}} The Dione Glacier lies on the southern slope, and the Rumbling Glacier lies to the northeast. Precipitation [runoff](/source/Surface_runoff) from the peak drains east into tributaries of the [Squamish River](/source/Squamish_River), or west into tributaries of the [Clowhom River](/source/Clowhom_River). The [first ascent](/source/first_ascent) of the mountain was made in 1916 by Tom Fyles and his brother, John Fyles, via the southeast ridge. The mountain names in the Tantalus Range have a [Greek mythology](/source/Greek_mythology) theme, and Mount Dione was named for [Dione](/source/Dione_(mythology)), the wife of [Tantalus](/source/Tantalus). The mountain's name was submitted by [Neal Carter](/source/Neal_Carter_(mountaineer)) of the [British Columbia Mountaineering Club](/source/British_Columbia_Mountaineering_Club), and was officially adopted on June 6, 1957, by the [Geographical Names Board of Canada](/source/Geographical_Names_Board_of_Canada).{{cite bcgnis|17364|Mount Dione}}{{cite cgndb|id=JBEYN|name=Mount Dione|access-date=2019-11-07}} ==Climate== Based on the [Köppen climate classification](/source/K%C3%B6ppen_climate_classification), Mount Dione is located in the [marine west coast](/source/marine_west_coast) climate zone of western [North America](/source/North_America).{{cite journal | author = Peel, M.

As a result, the Coast Mountains experience high precipitation, especially during the winter months in the form of snowfall. Temperatures can drop below −20 °C with wind chill factors below −30 °C. The months July through September offer the most favorable weather for climbing Dione. ==Climbing Routes== Established rock climbing routes on Mount Dione: * Southeast Ridge - {{YDS|3}} First Ascent 1916 * West Face - {{YDS|5.10b}} FA 1996 * West Buttress - {{YDS|5.10c}} FA 2002 ==Gallery== Alpha, Dione, Tantalus.jpg|[Alpha Mountain](/source/Alpha_Mountain) (left), Dione and Tantalus to right, as seen from the [Sea to Sky Highway](/source/British_Columbia_Highway_99) ==See also== {{Portal|Mountains}} * [Mount Niobe](/source/Mount_Niobe) (Niobe, daughter of Dione) * [Geography of British Columbia](/source/Geography_of_British_Columbia) * [Geology of British Columbia](/source/Geology_of_British_Columbia) ==References== {{reflist}} ==External links== {{stack|}} * Weather: [https://www.yr.no/en/forecast/daily-table/2-6080526/Canada/British%20Columbia/Mount%20Dione Mount Dione] * Mt.
