Mount Hood, the nearest major volcanic peak in Oregon, is 60 miles (100 km) southeast of Mount St. Helens. Mount St. Helens is geologically young compared with the other major Cascade volcanoes. It formed only within the past 40,000 years, and the summit cone present before its 1980 eruption began rising about 2,200 years ago. [ 11 ]
The ash cloud produced by the eruption, as seen from the village of Toledo, Washington, 35 mi (56 km) to the northwest of Mount St. Helens: The cloud was roughly 40 mi (64 km) wide and 15 mi (24 km; 79,000 ft) high. Ash cloud from Mt. St. Helens as captured by the GOES 3 weather satellite at 15:45 UTC.
The Mount St. Helens Visitor Center at Silver Lake, about 30 miles (48 km) west of Mount St. Helens and five miles (8 km) east of Interstate 5 (outside the monument), opened in 1987 by then-Vice President George H.W.

Management of the Earth's atmosphere involves assessment of all aspects of the carbon cycle to identify opportunities to address human-induced climate change and this has become a major focus of scientific research because of the potential catastrophic effects on biodiversity and human communities.
A fundamental concern of ecosystem management is the long-term sustainability of the production of goods and services by ecosystems, [9] as "intergenerational sustainability [is] a precondition for management, not an afterthought."
The other small raptor species commonly used in micro-falconry are the merlin, the sharp-shinned hawk (the smallest accipiter), and the European kestrel (a true kestrel). Hawking with the American kestrel requires adapting to the strengths and weaknesses of the bird.
The Mount Weather Emergency Operations Center saw the first full-scale activation of the facility during the Northeast blackout of 1965. [14] [15]According to a letter to the editor of The Washington Post, after the September 11 attacks, most of the congressional leadership were evacuated to Mount Weather by helicopter.
Micro-sustainability is the portion of sustainability centered around small scale environmental measures that ultimately affect the environment through a larger cumulative impact. [1] Micro-sustainability centers on individual efforts, behavior modification , education and creating attitudinal changes, which result in an environmentally ...
