zone, with long, cold, wet winters, and cool summers. 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 0 °F with wind chill factors below −10 °F. This climate supports the Eagle and Thiel glaciers surrounding the peak.
