What is Mount Meager?
[[Image:MountMeagerPlinthCapricorn.jpg|250px|thumb|The Mount Meager volcanic complex as seen from the east near Pemberton, BC.]] '''Mount Meager''' is a potentially [[active volcano]] in the Canadian province of [[British Columbia]], [[Canada]], 150 kilometers north of [[Vancouver]]. The top of the mountain is mostly covered by [[snow]] and [[glacier]]s. It lies in the [[Garibaldi Volcanic Belt]] and is the northernmost volcano of the [[Cascade Volcanic Arc]] that extends down to northern [[California]]. Its most common type of rock is [[lava]] that is almost a million years old (with a thickness in some places over 1&nbsp;km). The mountain is part of the [[Pacific Ranges]] of mountains and is 2,680 meters (8,793 feet) high. It was previously called ''Cathedral Mountain''. ==Geologic history== Meager is known for its last major eruption about 2,350 years ago. The strange thing about the eruption was the fact it released the debris from the northeast side of the volcano, as rock and ash blocked a major river called the [[Lillooet River]]. The river was dammed to a height of at least 100 meters, forming a [[lake]]. The lake reached a maximum elevation of 810 meters and was at least 50 meters deep. The breccia soon eroded from water activity within the lake, forming Keyhole Falls. There was a massive flood when the water first broke through the breccia, carrying small house sized blocks of breccia. During this eruption, ash was hurled into the air over 20 kilometers above [[sea level]]. The ash was carried eastward as far as [[Alberta]]. ==Volcanic hazards== Meager is an unstable volcano. It is built of unstable volcanic and has dumped clay and rock several meters deep into the Perberton Valley at least three times during the last 7,300 years. Two earlier debris flows, around 4,450 and 7,300 years ago, sent rubble at least 32 kilometers from the volcano. Recently, the volcano has created smaller [[landslide]]s about every ten years, including one in [[1975]] that killed four [[geologist]]s near Meager Creek. Logg
