A series of photographs taken from the International Space Station this summer show Mount Hood and Mount Rainier, two of the most iconic peaks in the Pacific Northwest, veiled by dense wildfire smoke. The images, captured in low‑Earth orbit, reveal how far the haze from regional fires has traveled, obscuring the volcanic summits and highlighting the widespread atmospheric impact of the 2026 wildfire season.
Wildfires in the Cascade Range erupted across Washington, Oregon, and northern California between May and August, producing vast plumes that drifted over the mountains and beyond. The ISS images, taken on July 12 and July 18, show the smoke layers settling over the peaks, reducing visibility to near zero from the ground and creating a dramatic visual of smoke‑filled sky.
The photographs were released by NASA’s Earth Observatory, which routinely publishes satellite imagery of Earth’s surface and atmosphere. The images were taken with the ISS’s onboard cameras, which capture high‑resolution scenes of the planet as the station orbits at about 400 km altitude. The resulting images illustrate the scale of smoke dispersion across the Cascade Range and the Pacific Northwest.
Why it matters
The images underscore the transboundary nature of wildfire smoke. While local news outlets reported on fire containment efforts and air‑quality advisories, the ISS photos provide a global perspective that shows how smoke from the 2026 fires has spread over thousands of kilometers. The haze has affected visibility along major highways, disrupted air travel, and posed health risks for residents and visitors in the region.
The smoke’s reach is also a reminder of the broader climate‑change link to wildfire activity. Rising temperatures and prolonged droughts have increased the frequency and intensity of fires in the western United States, which in turn release large volumes of carbon dioxide and fine particulate matter into the atmosphere. The images serve as a visual record of the environmental consequences of these fires and a call to address the root causes.
Background and context
The Cascade Range, a volcanic arc that stretches from British Columbia to Northern California, is home to 29 volcanoes, including Mount Hood (3,423 m) and Mount Rainier (4,392 m). These peaks are among the most active in the United States and are closely monitored for volcanic activity. In 2026, the region experienced a surge in wildfire activity, with over 1.2 million acres burned across Washington, Oregon, and California.
The 2026 wildfire season was the most destructive in the Pacific Northwest in over a decade. According to the U.S. Forest Service, the fires released an estimated 1.5 billion metric tons of carbon dioxide, roughly equivalent to the annual emissions of 200 million cars. The smoke plumes were tracked by satellite instruments such as NASA’s Moderate Resolution Imaging Spectroradiometer (MODIS) and the European Space Agency’s Sentinel‑2, which confirmed the extent of the haze and its impact on air quality.
The ISS images add a unique angle to the data. While ground‑based sensors and weather radars provide detailed information on fire behavior and air‑quality metrics, the ISS offers a bird’s‑eye view that captures the full spread of smoke across the landscape. The photographs also highlight how the smoke can obscure not only the peaks but also the surrounding valleys and human settlements, affecting both tourism and local economies.
What to watch next
Scientists and regulators will continue to monitor the smoke’s trajectory and its impact on air quality. The U.S. Environmental Protection Agency (EPA) is expected to issue updated air‑quality advisories as the smoke moves into the winter months, when temperature inversions can trap pollutants near the surface. Local governments are also likely to revisit wildfire prevention and mitigation strategies, including controlled burns and forest thinning, to reduce future fire risk.
In addition, the volcanic monitoring community will keep a close eye on Mount Hood and Mount Rainier. While the smoke does not directly influence volcanic activity, the heightened public attention to the region may prompt additional seismic and gas‑emission monitoring. Any signs of increased volcanic unrest could compound the hazards posed by the smoke and the ongoing wildfire season.
The ISS will also continue to capture images of the region as part of NASA’s ongoing Earth observation missions. The data will be used to refine models of smoke dispersion and to improve predictions of air‑quality impacts for future wildfire events.
Conclusion
The ISS photographs of Mount Hood and Mount Rainier shrouded in wildfire smoke provide a stark visual reminder of the far‑reaching consequences of the 2026 wildfire season. The images illustrate how smoke can travel across entire mountain ranges, obscuring iconic peaks and affecting air quality for millions of people. They also highlight the importance of satellite observations in understanding the scale of environmental disasters and in informing public policy. As the region continues to grapple with the aftermath of the fires, the images serve as both a record of the event and a warning of the need for comprehensive wildfire and climate‑change mitigation strategies.
