danger. Temperatures in winter can drop below −20 °C with wind chill factors below −30 °C. This climate supports a small glacier in the cirque north of the peak. During winter months, weather is usually cloudy, but due to high pressure systems over the Pacific Ocean that intensify during summer months, there is often little or no cloud cover during the summer. The months July through September offer the most favorable weather for viewing or climbing this peak.
