RAIN =
MUDFLOWS --- The 1972 Big Sur Molera Fire & Mudslides
Something that wasn't mentioned in the mudslide article was the temporary damning of the river at Juan Higuera Creek and the Big Sur River ( Actually this may have been in 1976). The area south of Juan Higuera Creek to the 90 degree turn in the river at Fernwood was turned into a lake for about half a day. The water floated the swinging bridge just north of the Catholic church, I know because I crossed it while it was floating. If I remember correctly this mass of water when it breached the blockage helped to move a lot of debris and silt accumulating at Pheneger Creek. A lot of water will accumulate in this area as I recall it is the greatest gradient in the river, i.e. from Fernwood north to Juan Higuera Creek.
The river was surveyed from North to South and from South to North and the surveyors met at our property and were about 10' off from each other. The actual high water mark was at the lower of these two surveys.
After the Marble Cone fire during October at the first significant rain I watched the river surge over 6 feet at this area and drop back to normal in just a couple of hours. That was sort of a flash flood occurrence and could be a very serious problem this year depending on the intensity of the early rain, especially with the area burned.
Another , now amusing but dangerous thing was the alert system placed as a series of horns or sirens along the Big Sur Valley. When the rain hit a certain intensity at the peaks, the sirens went off but no one could hear them as the intensity of rain in the valley was so noisy it drowned the sound of the system.
I also remember vividly the fear and insanity of the cutting of trees along the river and the bulldozing of the river channel. The scares are permanent and the river never returned to its original beds. Hans Ewalson and Vic Pfeiffer were at odds as to owned Pheneger Creek and I guess the bulldozers &/or the mud slides decided that. We need to be careful of what is done and the preparations as lots of mistakes, I decisions were made without really knowing the outcomes of the work.
That's my 2
cents. And thanks Gary, how
fast it becomes history.

from the
Past--too vivid, all this
That was 1977 indeed.
That's when the river was at flood stage behind River Inn.
We watched it from the Outdoor Classroom that overlooks the river at
Captain
Cooper School.
And yes, I have a photo somewhere.
At night (which by the way is when most of the worst slides happen),
Doug and I
could hear
logs and picnic tables from Riverside and Big Sur Campgrounds hitting
the
bridge just downstream from River Inn--
punctuated by an occasional small propane tank. Those had a
distinctively
different sound! Don would remember
if any larger ones floated down. This is all stuff I've said before,
but don't
know if I've written. All the flats, from the State Park
to Jap Flats (Sorry, I don't know any other name for the place below
Cooper
where the Molera Fire started Maybe the flood will earn us one).
Anyway,
anything that was a flood plain in geologic history made a lake of
itself for
many days. It flooded the group campsite at the State Park. This brings
to mind
something that a number of folks had concerns about when it went in,
and that's
the sewage treatment facility just south of the entrance to the State
Park.
People expressed doubts about placing the leach field on that flat next
to the
river, a no-no if that were private property. Just a health heads up
for those
downstream during all this.
As to the siren, I respectfully have to differ. It went off twice that
I know
of--one of those times Doug and I and baby Noel were AT THE STATE PARK
in my
rust-red 1976 Volvo that had 198,000 miles on it. I've never driven so
fast
through the valley in my life. Doug thought
I'd get all three of us killed, but I had visions of a wall of water
lapping up
behind us and I just hauled! We heard all six sirens with no silence in
between. We slid into that Apple Pie dirt road like someone had thrown
us in a
roller derby. I couldn't get high enough fast enough. Even at the house
(first
house on Apple Pie Ridge Road--bordered by Pheneger) I wondered if we
were high
enough, but finally reasoned that we just had to be. Turned out that
the rain
sensor had to be re-calibrated. The next time, I was home when it went
off. The
work they did to get the logs in six foot lengths made all the
difference.
Flood, yes. Flash flood, no. No question there was enough material to
cause a
logjam in the Gorge. That certainly goes for now--in spades!
Bob is spot on as to the bend in the river south of Juan Higuera and
the potential
for causing a blockage. Anything that blocks the flow can be considered
armed
and dangerous. That's one reason the Grange had problems. Mostly though
the
berm and sandbags protected the integrity of the structure. Water got
inside
though--I think in '72 and '77. I remember the worries that the bank
was
saturated and the area on the river side kept sloughing off. We thought
it
could take the little house behind the Grange (which is no place to be
once the
first rain cloud forms).
