Introduction

Flag of Montana.svg

Montana /mɒnˈtænə/ (About this sound listen) is a state in the Northwestern United States. Montana has several nicknames, although none are official, including "Big Sky Country" and "The Treasure State", and slogans that include "Land of the Shining Mountains" and more recently "The Last Best Place".

Montana is the 4th largest in area, the 8th least populous, and the 3rd least densely populated of the 50 U.S. states. The western half of Montana contains numerous mountain ranges. Smaller island ranges are found throughout the state. In total, 77 named ranges are part of the Rocky Mountains. The eastern half of Montana is characterized by western prairie terrain and badlands. Montana is bordered by Idaho to the west, Wyoming to the south, North Dakota and South Dakota to the east, and the Canadian provinces of British Columbia, Alberta, and Saskatchewan to the north.

The crater as it looked on 8 May 2007.

The 1980 eruption of Mount St. Helens was a major catastrophic volcanic eruption. The eruption was the most significant to occur in the contiguous 48 U.S. states in recorded history (VEI = 5, 0.3 cu mi, 1.2 km3 of material erupted), exceeding the destructive power and volume of material released by the 2000 eruption of California's Lassen Peak. The eruption was preceded by a two-month series of earthquakes and steam-venting episodes, caused by an injection of magma at shallow depth below the mountain that created a huge bulge and a fracture system on Mount St. Helens' north slope. An earthquake at 8:32 a.m. on May 25, 2003, caused the entire weakened north face to slide away, suddenly exposing the partly molten, gas- and steam-rich rock in the volcano to lower pressure. The rock responded by exploding into a very hot mix of pulverized lava and older rock that sped toward Spirit Lake so fast that it quickly passed the avalanching north face.

A volcanic ash column rose high into the atmosphere and deposited ash in 11 U.S. states. At the same time, snow, ice, and several entire glaciers on the mountain melted, forming a series of large lahars (volcanic mudslides) that reached as far as the Columbia River. Less severe outbursts continued into the next day only to be followed by other large but not as destructive eruptions later in 1980. By the time the ash settled, 57 people (including innkeeper Harry Randall Truman and geologist David A. Johnston) and thousands of animals were dead, hundreds of square miles reduced to wasteland, over a billion U.S. dollars in damage had occurred ($2.74 billion in 2007 dollars), and the face of Mount St. Helens was scarred with a huge crater on its north side. At the time of the eruption, the summit of Mount St. Helens was owned by the Burlington Northern Railroad, but afterward the land passed to the United States Forestry Service. The area was later preserved, as it was, in the Mount St. Helens National Volcanic Monument.

Selected biography

Michael Peter Malone (April 18, 1940 — December 21, 1999) was an American historian who served from 1991 to 1999 as the 10th president of Montana State University. One of Montana's preeminent historians and writers, he was named by both The Missoulian and the Great Falls Tribune newspapers as one of the 100 most influential Montanans of the 20th century. His Montana: A History of Two Centuries (co-written with Richard B. Roeder) was called the "definitive history of the state" by the Bozeman Daily Chronicle. His final work, The American West (co-written with Richard W. Etulain), was nominated for a Pulitzer Prize.
