Wildfire Smoke Shrouds Cascade Volcanoes Amid Hot, Dry Conditions
• In the summer of 2026, wildfire smoke enveloped prominent glaciated peaks in the Cascade Range, including Mount Hood in Oregon and Mount Rainier in Washington. Astronauts aboard the International Space Station captured striking images of the smoke mingling with these iconic volcanoes. The Grasshopper Fire, ignited by a lightning strike on July 23, 2026, near Mount Hood, had burned approximately 84,000 acres (34,000 hectares) by August 12, spreading rapidly under hot and dry conditions. Meanwhile, Mount Rainier experienced smoke from fires in central and eastern Washington, with air quality in the national park reaching unhealthy levels on August 4 due to elevated PM 2.5 concentrations. The Grand Park 2 fire, burning within Mount Rainier National Park, had consumed 223 acres (90 hectares) as of August
• Above-normal fire potential is expected to persist across the Pacific Northwest due to El Niño-influenced warm and dry weather.
Impact & Risks
The wildfires have significantly impacted air quality and local communities. Wasco County, Oregon, issued 'go now' evacuation orders for several areas, and residents of Dufur were advised to prepare for immediate evacuation. In Washington, Mount Rainier National Park visitors faced unhealthy air quality levels due to smoke from distant fires. The ongoing dry and warm conditions, combined with cured vegetation, have heightened the risk of large, long-burning wildfires in the region. These conditions pose threats to public health, property, and natural ecosystems.
