Learn more about the Cascadia Volcanic Arc© ™ ® (Part of Pacific Ring of Fire) Cascadia Volcanoes© ™ ® and the currently active Mount Meager Massif© ™ ®, part of the Cascadia Volcanic Arc© ™ ® [ash flow, debris flows, fumaroles and hot springs], just northwest of Pemberton and Whistler, Canada ~ My personal interest in the Mount Meager Massif© is that the last volcanic vent blew north, into the Bridge River Valley [The Bridge River Valley Community Association (BRVCA), [formerly Bridge River Valley Economic Development Society], near my hometown. I am the Man From Minto© ™ ® - A Prospector Who Knows His Rocks And Stuff© ™ ® Mount Meager Massif© lahar was the largest landslide in Canadian history and one of over 20 landslides to have occurred from the Mount Meager massif in the last 10,000 years. This lahar [a large catastrophic debris avalanche] that flowed to the south, into the Lillooet Valley British Columbia, Canada, on August 6 at 3:27 a.m. PDT (UTC-7). More than 45,000,000 m3 (1.6×109 cu ft) of debris slid down Mount Meager, temporarily blocking Meager Creek and destroying local bridges, roads and equipment. The landslide was large enough to send seismic waves more than 2,000 km (1,200 mi) away into the neighbouring U.S. states of Alaska and Washington and beyond. Multiple factors led to the slide: Mount Meager's weak slopes have left it in a constant state of instability. The massif has been a source of large volcanic debris flows for the last thousands of years, many of which have reached several tens of kilometres downstream in the Lillooet River valley, to the south. It is arguably the most unstable mountain massif in Canada and may also be its most active landslide area. On the north side of the large Mt. Meager massif volcano complex lies Downton Lake Hydro Reservoir, impounded by the La Joi Dam, the uppermost of the Bridge River Project dams. The earliest identified Holocene landslide was in 7900 BP (before the present, or read it as the number of years ago). Further landslides occurred in 6250 BP, 5250 BP, 4400 BP, 2600 BP, 2400 BP, 2240. BP BP, 2170 BP, 1920 BP, 1860 BP, 870 BP, 800 BP, 630 BP, 370 BP, 210 BP, 150 BP and in 1931, 1947, 1972, 1975, 1984, 1986 and 1998. These events were attributed to structurally weak volcanic rocks, glacial unloading, recent explosive volcanism and glacial activity. The last volcano on the top of the massif, however, blew to the north 2,460 years ago, sending talus all the way to Alberta. At the Gold Bridge Golf Course, Bridge River Valley, BC you can play the nine hole course on that talus. .

Is a dormant volcano near Pemberton ready to blow? - Damn. NO ! Its NOT DORMANT.

When I was 23 months old, in 1946, the M7.3 Forbidden Plateau Earthquake was my personal first.  My second, just three years later in 1949, Canada's,biggest ON RECORD, an M8.1.

That was NOT WESTERN NORTH AMERICA'S BIGGEST.  Those have happened repeatedly, 40 times in the last 10,000 years.  The last great quake, an M8.8-9.3, happened on January 26, 1700 AD, 9PM.  Every First Nation, all up and down the entire west coast of North America have the same story.  Everybody.  The Japanese have written records going back thousands of years.  The geologic scientific evidence is complete.  As the strain builds up from when the North American Tectonic  just waiting the next event

Trying to predict an unpredictable volcano is a MUGS game.  If you're right about a volcano being dormant, no one will care.  If you're wrong about it, and eruption occurs, you'll kill a lot of of flora and fauna, including people, all around.

When I was growing up in Minto, in the Bridge River Valley, BC, we talked about seismic events, a lot.  When I was three years old, Frenchie, an old prospector, my friend, mentor and teacher explained that all of the gold lying all around was a result of volcanic activity, forced up in quartz-gold veins along fault lines.  Frenchie was building a beautiful 30 x 40 foot log cabin on the north side of the main road.  He often invited us Minto kids in for cookies, tea and a visit.

Frenchie began teaching me about gold mining.  He put a bead of mercury into my right palm and showed me how to use it to form an amalgam with gold, to pull the gold out of the black sand in a placer operation or out of crushed gold-quartz in a hard-rock operation.

In the winter Frenchie put the pointy end of a shotgun under his chin.  I miss him still.
