Thanks, Robert. That helps a lot. Sounds like I'm right on the edge of one of the threatened areas.

Any chance you could scan in that map for all to see?
The maps are very large, 3ft by 2ft.  I received them from "Wrightwood".

You're in luck as I did scan the map (link below) a while back and have done a good deal of research on scientific studies conducted over the years.

Some time (in between major projects I'm involved in) I'd like to do a web page on mud flow activity in Wrightwood and include many of the scientific studies that have been scanned.

Like RobertW mentioned... It's amazing that the slide didn't break loose 2 years ago as most of upper Heath Canyon slide developed major fissures around its perimeter. (photo documented)

Many property owners in Wrightwood have graded their property to divert the flow of water from their properties.
This seems to have worked for light precipitation.
I'm thinking that a good flow would put things back the way they were (or change the lay of the land in new ways).

sweet!  i live closer (in my tent) to the narrowed base of the Heath Slide than anyone else in the whole universe!   :2thumbsup:

last Christmas a debris flow came down via one of our hiking trails.  it obliterated the trail with gravel and boulders, as well as gouged out 3-5 feet deep channels into the former trail (in some places).  unfortunately, this trail leads directly toward the middle of our camp.  some of the water flow has shifted it's course to the west of the Levee now.  but more talc, tourmaline and actinolite, as well as some pretty interesting schists were exposed there...

Nothing beats a good schist pun ;D

Thanks for the map Wrightwood. That's a big help.

How about trying to pan for some gold?

i have found gold in the American River outside Sacramento in the past...about 3.1 ounces.

i should try around here in the spring.

Why wait for spring ? there's places to search now.

 Mine Gulch stream that feeds into the SanGabriel river has had water flowing all summer. It gets fed from Baden Powel underground sources. It's bit of a hike and makes for a nice day trip.

The Ord Mtn. and Stoddard area is also good for many minerals all year, including gold.

 There's a lot of Actinolite in our area, I have some going in the polisher now.

Now that we are faced with warm rain in the forecast it's time for this topic to be revisited.

We've spent a great deal of time in the area of Heath Canyon placing a solar powered livecam and documenting bighorn sheep movement.

Changes that took place between 2004 & 2005 on the slide during winter/spring were dramatic to say the least. Most vegetation in the bench area (near the top) had disappeared between the livecam and upper slide. Fissure activity first appeared as snow creep during January 2005. (as seen in this livecam image below)



Below are pictures a few months later showing the fissure activity that had developed during the 2004/2005 winter. The entire upper section or bench area of Heath Canyon slide is fractured.

EEeek!  I've been out on the "plateau" part of the slide twice, and both times I've needed a hand getting down a little bit of steep steps getting out there.  I can get UP it OK, I'm just terrified of even a little bit of steep downhill.  But these trips have been in the summer.  Let's just pray that the mt. holds during this storm... :)

Is the Mud Slide in Slip Side?

I took this photo of the slide this morning and it looks like the warm weather and snow melt is making it slide again

Yea there is some movement up there. I have some pictures before the snow, I'll have to go find them. Good thing I'm on Cedar.

My friends place backs up to that wash.. it's amazing the stuff the comes down when is flooding.  The noise is something else also.  When cracks in the ground at the top of the slide are impressive and leaves no doubt in your mind things are moving up there. 

Like the 'big one' it's probably only a matter of time before  another big slide comes down. 

Hopefully we see it happening before it all breaks loose.
