The Night the Mountain Fell: The Story of the Montana-Yellowstone Earthquake

Earthquakes -- Montana; Earthquakes -- Yellowstone National Park
This awesome and fascinating earthquake area quickly became one of the
region’s top tourist attractions, with close to half-a-million visitors
in attendance during each of the first two post-quake summers, in spite
of miserable to nearly impassable access roads. This popularity is
especially fitting because the quake that’s on display here was
essentially a “tourist earthquake”. It happened in the scenic mountain
area which draws a brisk vacation traffic from all over the U. S. and
Canada, during the height of the tourist season. And those who went
through the adventure, the thrills, the terror, the heroes and the
helped, the survivors, and the casualties, could nearly all be classed
as tourists.

Superb trout fishing has always been one of the area’s most important
features, and, understandably, there was much post-quake concern as to
how this would be affected. While Hebgen Lake was drained to repair the
quake-damaged Hebgen Dam, Montana’s Fish and Game Department poisoned
the trash fish and stocked the refilled lake with millions of rainbow
trout running in size from fingerlings to 9-inchers. Today both Hebgen
and Quake Lake—formed by the damming action of the slide at the mouth of
Madison Canyon, afford top fishing, either from shore or from boat.
Quake Lake has a made-to-order launching ramp at Cabin Creek, where the
flooded-out road runs right into the lake.
In spite of the concern by fish biologists that silting from the slide
would take the edge off fishing on the Madison below the slide area, it
kept right on providing fishermen the top-notch action that had long
earned its reputation as a blue-ribbon trout stream that compares with
fishing anywhere in the world.
Today there are excellent roads to and through the Earthquake Area.
Route 287, south from Ennis, leads directly to the huge slide at the
mouth of Madison Canyon. Here the Forest Service has built a surfaced
road up onto the slide. On top is the best vantage point to view the
whole panorama of the mountain fall—where it dropped from, how in a
matter of seconds 80-million tons of rock cut off the valley, the
sparkling blue lake it created, and the open stretch of the Madison
below the canyon. Besides, on the slide there are interpretive exhibits,
and the huge monolith bearing the plaque to the quake dead, 21 of whom
still lie somewhere beneath this mammoth pile of rock.
The relocated route runs eastward down the slide, along Quake Lake, and
through Madison Canyon. Several Forest Service people staff the formally
designated Earthquake Area during the summer season to help explain and
interpret what happened here. Definite plans for the area include a
formal visitor center, and at least one first-class campground in the
slide-lake-canyon area.
