Yesterday morning was pretty weird. It had been raining, hard at
times. Then it let up. Then we heard rumbling. I asked Jim
if he thought it was thunder, then we decided not. I looked out the
front window at Golden Gate and this is what I saw. See the lower
cloud-ish looking area, below the actual clouds on the top of the
mountain? That's dust, it's from a land slide. At the top of the
mountain, something fairly large let go and headed down hill.
The arrows are pointing at two of the boulders that came down. It was
surreal how much noise it made.
A lot of dirt came down, and many saguaros lost their lives today. It's very sad, some of them are over 100 years old, and now they are dead.
So, this was before.
And this is after. It's a subtle change. The next photo is better.
Look at where the white arrow is pointing. The arrow is difficult to see because picassa would not let me bold it for some reason. It's at the top of the photo. Anyway, see the flat shiny surface? That used to be a good sized rock jutting out. Now it's gone.
Remember I mentioned that in the past Tucson had used major thoroughfares to
carry water, instead of putting in storm drains? I guess the thinking
was that the major dry rivers would handle the rainfall in a bad year.
That was true until fall of 1983. I was in school here then. The
previous winter had been wet, monsoon 1983 was very wet, so the ground was
saturated. Then tropical depression Octave came and rained from
September 28 until October 3. The airport got 6.7 inches of water in
that period. There was massive flooding and bank erosion in the river
beds. Houses fell in to the water, and I think 10 people were
killed. In today's dollars, damage was about a billion. After
that, Tucson got serious about water management.
Here you can see bridges have been removed by severe bank cutting.
More washed out bridge.
There are a couple of old articles about 1983 that are interesting.

Blogger is getting weirder on me, so I think I will publish this while I can. Some days the software will just not cooperate, no way - no how.
