Human History
The term Stikine Volcanic Belt was originally defined by Jack Souther and Christopher Yorath of the Geological Survey of Canada in 1991 as a group of volcanic deposits centered around the Stikine River in northwestern British Columbia. As more mapping and dating of volcanic deposits was completed in the Western Cordillera, the Stikine Volcanic Belt was expanded to include volcanic deposits further and further from the geographic area associated with the name Stikine. In part for this reason, scientists Ben Edwards and James Russell redefined this area of volcanism as the Northern Cordilleran Volcanic Province. As a geographic descriptor, application of the name Stikine to volcanic rocks exposed along the Yukon River seems a bit odd and confusing. As well, a much older group of totally unrelated volcanic rocks comprise the Stikine Assemblage, which also mainly occurs within the geographic area informally referred to as Stikine Country. The Northern Cordilleran Volcanic Province is a broader name, to encompass a broader geographic area, in which the most recent volcanism has a similar character (mainly alkaline, mafic volcanic rocks), a similar age range (Miocene to Holocene), and a similar tectonic setting (transtension).

Famous quotes containing the words human and/or history:
“All I know is that first, you’ve got to get mad. You’ve got to say, ‘I’m a human being, goddamn it, my life has value.’ So I want you to get up now, I want all of you to get up out of your
chairs. I want you to get up right now, and go to the window, open it, and stick your head out, and yell, ‘I’m as mad as hell, and I’m not going to take it anymore.’”
—Paddy Chayefsky (1923–1981)
“These anyway might think it was important
That human history should not be shortened.”
—Robert Frost (1874–1963)
