Even the one place on SR 330 they've shown on the news* will take at least
weeks, if not months, to repair. (Correction: The KCBS/KCAL Website has a
story on this (Jan 6) that says "years".)

Question: When you have nothing but air, how do you build a road on it?
(Hint: It's not like a sinkhole where the land around the hole still

And of course, the land that remains is not stable, so even if they could
just go in and rebuild, they can't go in until everything dries out without

Thanks for posting this, Kim. The devastation
created by this inundation of rain will take some time to be resolved.

"The mountains received totals of 10 to 28 inches, highest in
the Lytle Creek drainage and Crestline area. "

Our rain gauge in Crestline (5200 feet) recorded
over 33 inches of rain during the six day period
described below. (We're showing over 46 inches
for the season so far.) I'm sure it was more in
the higher elevations that were below snow
level. It truly was relentless at times. (One
day over 10 inches, one day over 8 inches and one day over 6 inches of

This is what brought down Highway 330, the major
artery to Running Springs and the Big Bear
area. There is not much media coverage of this
event but since the road repair is expected to
take at least one year Running Springs and Big
Bear area merchants have already suffered
greatly, and will suffer more. Some are likely
to loose their livelihoods due to this
closure. Any patronage of them would be most appreciated, I'm sure.
