Importance of Crater Lake National Park
The state of Washington's Mount
St. Helens offers a tremendously exciting opportunity for serious scientific
study of the immediate effects of a volcanic explosion on the environment.
Oregon's Crater Lake, on the other hand, enables visitors to comprehend the
regenerative abilities of the earth after volcanic activity. Here one can look
without fear but with a sense of awe over a land that bears the scars of an
earlier violence already partially healed by forest and meadow. The landscape
and scenic details of such a volcanic area are unique among other national park
units:
of the several processes of world-making, all of
which are progressing to-day at normal speed, none is so thrilling as volcanism,
because no other concentrates action into terms of human grasp. Lassen Peak's
eruption of a thousand cubic yards of lava in a few hours thrills us more than
the Mississippi's erosion of an average foot of her vast valley in a hundred
thousand years; yet the latter is enormously the greater. The explosion of Mount
Katmai, the rise and fall of Kilauea's boiling lava, the playing of
Yellowstone's monster geysers, the spectacle of Mazama's lake-filled crater, the
steaming of the Cascade's myriad bubbling springs, all make strong appeal to the
imagination. They carry home the realization of mysterious, overwhelming power.

As early as the 1880s J.S. Diller
of the Geological Survey said of Crater Lake that it "affords one of the most
interesting and instructive fields for the study of volcanic geology to be found
anywhere in the world." Ancient Mount Mazama has been important in scientific
circles because of the variety of ways in which the ash from her eruption, which
can be easily identified by the particular minerals it contains, can be utilized
in geological studies: helping to date archeological discoveries in the
Northwest; helping to formulate a timetable of glacial movement and melting
patterns; helping to determine the length of time it has taken modern soils to
develop from various types of deposits; functioning as a time marker in
establishing geologic chronology; and helping to determine types of early plant
life by its position above or below the pollen immersed in bogs.

Through the years Crater Lake and
its surrounding forest lands have been the subject of research in the fields of
geology, archeology, paleontology, botany, geography, limnology, zoology,
ecology, biology, and physics by scientists from this country and around the
world.
