In this week’s Video of the Week, take a three-dimensional tour of Mount Baker, an active stratovolcano in Washington state. At 10,781 feet (3,286 meters), Mount Baker is the highest peak in the North Cascade Range and the northernmost volcano in the contiguous United States. It is also the only Cascade peak to be affected by both alpine and continental glaciation.
Twelve principal glaciers exist on Mount Baker, all of which are in rapid retreat. The peak is consistently one of the snowiest places on Earth. Mount Baker set the record for snowfall in a year, when it received 95 feet (29 meters) in 1998-1999, an El Niño winter.
Mount Baker is in the news this week after venting steam from a crater near its peak. Though the most recent major eruption at Mount Baker occurred 6,700 years ago, the 2018 update to the USGS National Volcanic Threat Assessment lists the volcano’s eruption threat as “very high,” the most cautious categorization. Volcanoes with this designation are prioritized for research, monitoring, and mitigation.
According to ScienceBase.gov, the USGS data release portal, the purpose of the Mount Baker survey was to contribute to natural hazards monitoring efforts, the study of regional geology and volcanic landforms, and landscape modification during and after future volcanic eruptions.
The rendering below, published by the US Geological Survey in November 2017, used a high-precision Light Detection and Ranging (LiDAR) survey. LiDAR is a remote sensing method that uses light in the form of a pulsed laser to measure ranges to the Earth to generate precise, three-dimensional information about the shape of the Earth and its surface characteristics. A Leica ALS80 system mounted in a Cessna Caravan 208B was used to conduct the Mount Baker survey in the fall of 2015.
