Mount Sentinel
Encyclopedia
Mount Sentinel, originally known as "Mount Woody," is a small mountain located to the east of the University of Montana in Missoula, Mont
. At a height of 1,958 feet and an elevation of 5,158 feet, Mount Sentinel also features the hillside letter "M", a large concrete structure 620 feet up its western face.
Glacial Lake Missoula
Between 15,000 and 13,000 years ago, a Pleistocene Ice Age glacier moved through the Purcell Trench in northern Idaho, damming the Clark Fork River. This glacial dam created Glacial Lake Missoula
, a lake larger than Lake Erie
and Lake Ontario
combined. As the lake continued to grow, pressure increased on the glacial dam, ultimately causing the dam to fail. Water from the lake rushed westward at speeds between 30 and 50 miles per hour across Montana, Idaho, and Washington. The violent flow created by the draining of Glacial Lake Missoula
left shoreline marks that are still visible on the face of Mount Sentinel and Mount Jumbo
, a neighboring mountain to the north.
The first trail up Mount Sentinel to the area that the "M" would later occupy was cut by forestry students in 1908. In 1909, the junior class constructed the first "M" at the top of that trail with whitewashed rocks. In 1912, the freshman class constructed a small white "M" of wood. This "M" stood upright on the face of the mountain and cost $18 dollars to build. The wooden "M" was destroyed by wind in 1914, replaced, and then wrecked by wind again. In 1915, a new "M" made of whitewashed rocks was constructed 200 feet above the original "M" site. A concrete "M" measuring 125-by-100-feet was built in 1968 at a cost of $4,328. The concrete structure was built because it was no longer feasible to maintain the old, rock "M". This concrete "M" is still located on Mt. Sentinel today.
Tradition
Between 1915 and 1968, while the "M" was composed of whitewashed rocks, freshman boys hiked the trail to the "M" each year to apply a fresh coat of white-wash. The tradition ended with the construction of the cement "M".
Starting in 1919, freshman boys hiked the trail to the "M" during homecoming and lit the outline with railroad lanterns. This tradition continues today, with UM Advocates making the hike each year at homecoming to light the "M".
Each year, during Native American Awareness Week, a sunrise ceremony is held at the base of the "M" where traditional Salish Morning and Honor Songs are sung.
Vandalism
The freshman class of 1914 hiked up Mount Sentinel to whitewash the "M", but instead rearranged the rocks into a "'14". When they descended the mountain they were met by members of the sophomore class and forced to hike back up the mountain and place the rocks back into the shape of the "M".
After the Grizzlies of the University of Montana beat the Montana State University Bobcats (known then as the Aggies) in 1920, a group of Aggies fans climbed up the "M" and painted it bright blue and gold. Early the next morning, a Grizzly fan noticed the letter's new coat of paint, roused some fellow fans and re-painted the "M" white before most Missoula residents even noticed.
In 2006, outdoor retail co-op REI
, which gave away $1 million in grants to nonprofit groups dedicated to preservation of community parks, awarded a $10,000 grant to Friends of Missoula Parks for use on improvements to Mount Sentinel.
After a fire in 2008, the conservation lands manager for the city of Missoula and a University of Montana natural areas specialist teamed up to spread native grass and flower seeds over the area of Mount Sentinel that was burned.
In the fall of 2010, the University of Montana Student Guild of the Society for Ecological Restoration teamed up with Run Wild Missoula and other volunteers to help restore the "M" trail. The group added gravel to the path, reseeded barren areas, blocked unwanted side trails, and added more steps to the eighth switchback.
In 2010, local environmental activists added a white "350" made of tarps next to the "M" on Mount Sentinel. The display was organized as a part of the 350.org organization's 10-10-10 Global Work Parties effort. Over 7,000 work parties worldwide did projects to decrease carbon and heighten the awareness within political circles in order to slow climate change.

More recently, over 300 acres on Mount Sentinel's west slope, directly above the University of Montana campus, burned in July 2008.
At least 20 acres also burned in July 2006.

History
The University of Montana first received land on Mount Sentinel in 1902 when the Northern Pacific Railroad Company donated 40 acres at the foot and up the slope of the mountain. The U.S. Congress later turned over many acres of Mount Sentinel so that campus extended up the slope to the crest of the mountain, making the University of Montana the only university in the nation to own a mountain. In 2000, the city of Missoula also purchased 475 acres along the face of Mount Sentinel.Glacial Lake Missoula

Activism
In 2005, students of Missoula's Hellgate High School staked a 50-by-20-foot red ribbon next to the "M".
