Mount St. Helens and its sister volcanoes
By DAVID LESTER
YAKIMA HERALD-REPUBLIC
In geologic terms, she is just a precocious child.
Only 50,000 years old, Mount St. Helens' life span pales compared
to majestic Mount Rainier to the north, a peak that has been around
for a half-million years.
But St. Helens has been busy in its young existence. It is now
the most active volcano in the Cascade Range, which stretches from
northern California to British Columbia.
According to the U.S. Geological Survey, Mount St. Helens has
erupted 14 times in the last 4,000 years. Northern California's
Mount Shasta and Medicine Lake Volcano are the next most active
peaks, with seven eruptions during that time.
