. The spelling "Grenelle", although misconstrued, is firmly entrenched in the mountaineering community, according to April 1978 advice from Dr. Glenn Woodsworth, Geological Survey of Canada and Alpine Club of Canada representative to the Geographical Names Board of Canada. The "Grenelle Mountain" toponym was officially adopted May 1, 1978, by the

), 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. Temperatures can drop below −20 °C with wind chill factors below −30 °C. This climate supports the Waddington, Splendour and Tiedemann glaciers which cover the slopes of Grenelle Mountain.
