Primary Interest:
Prospecting
Sadly, this morning there was a massive landslide that took
place near the town of OSO, located on the North Fork of the
Stillaguamish River.

The slide took out several homes, and has also claimed at least
3 lives. The town of Darrington is completely cut-off from access
on Hwy. 530, and the highway is totally blocked by a massive wall
of mud and debris.

Worse yet, the N.F. of the Stillaguamish (aka: Stilly) is completely
blocked by the slide, causing a massive build-up of water on the
upstream side.

There are real-time river level monitors placed all along our major
rivers, and the one for Arlington shows a very serious issue
developing...all the water is backing up miles above the mid-sized
town of Arlington, which is built just off the banks. Lord help them
if that obstruction blows out all at once, as a massive flash-flood will
go racing down the river channel, blowing out everything in it's path.

Here is the current level in Arlington (Note the drop!)

The Stilly is also a major Salmon and Steelhead spawning river, and
the lack of water downstream is exposing all the redds (eggs) to
the open air...they won't survive.

There is currently an effort by a group of elitists to stop all suction
dredging for gold in the state because they *think* we cause loss
of fish habitat. Maybe they should be taking on Ma Nature instead,
as the damage done from this one slide is a 100³ times worse than
all the dredging combined for a 10 year period!

I prospect this area frequently, and my thoughts and prayers go out
to the families there, many of which I've met at one time or another.

Hopefully, the blockage can be cleared out slowly, but if it all goes at
once the amount of property and river damage will be very significant.

Sorry to hear this. My wife and I were in that area last summer. Gorgeous country. I'd bet that slide will go all at once...they usually do, unless they can get in there and reinforce the "dam" so it will hold through the high-water season. Bad business.

Maybe they should have dynamited it earlier. :dontknow:
 

so sorry to hear of this tragedy
mine & my families condolences
to all the victims

Dynamited what earlier? A whole mountain side came down...this morning,
and that's what created the blockage.

Tried to call some friends over that way, but they're most likely out
doing what they can to help neighbors.

Wow !!!!!!!!! That is a huge slide area. That will definitely leave a mark for a long time to come. More than likely going to get worse before it gets better in that area as well. I hope they are able to prevent a sudden release of that water , or they will have one he!! of a flood. Dennis

Sorry. I didn't realize everything when I first read it. I hope and pray things don't get worse.
 

JC, thanks for sharing those pics. When I first saw the one on top,
it scared hell out of me to see just how much of that mountainside
had slid. Slides aren't uncommon up here, but I've never known of
one this massive.

If you look close at the location on Google maps, you will see Dicks Creek
and Rollins Creek; I've prospected areas near both, and never once
considered that the side of that hill could come down. If you follow the NF.
of the Stilly all the way to Arlington, you can see just how many houses, farms
and properties will be devastated if that mud/debris dam blows out.

Heard from a local that there is still water getting by the landslide,
and plan to drive over there tomorrow and see if they need help
with clearing debris. I'm only 10 mi. from there (as the crow flies),
and live on the north side of the same range of the hills.

Been looking at Google maps, and as best as I can see that hillside
slid for close to a mile before hitting Hwy. 530. A massive amount
of material, and it will change the landscape of that valley forever.

The slide appears to be between 1/2 and 3/4 a mile wide. It wouldn't apear that enough water would build up to blow out that wide of a blockage all at once. It will eventually find the weakest spot and cut a new channel in short time. I pray my theory is correct or else God protect those folks if it does go at once. This only shows how arogant humans are to think we have the power to do any signifficant damage to this planet outside of nuking it. Mother nature did in a matter of days and hours what an army of hydro monitors would take years to do. Wish I lived closer so I could help. Good luck and prayers to all out there.
 

GGGGGGGGGGGGGGGGGGSSSSSSSSSSSSSSSSSSSSSSSSSSS a bign' fer sure. Mother natures fury can be deadly for sure. Truly hope they get going asap to divert that water asap or else all LL is gonna breal loose. Huge bummer to see-John PS--$5'll get ya $10 they'll blame miners fer sure :BangHead: John
 

They'll blame miners for sure and global warming as well.
 

So very sorry to hear of the human loss:....Lives and property. A tragic event! Many natural lakes are created by such events. Such events have molded the face of this planet for 4.5 billion years. In scale to other such events this is probably miniscule....yet a tragic natural event. This event is going to be difficult for man to handle. Movement of material is common; and as gold miners we seek out areas of such events when the occur in "gold country".

Currently I am on my claim south of Rich Hill Az and there is/are existing ancient "debris flow(s)" and "alluvial fan deposits" that contain UNSORTED placers. Such areas, when and if they are in "Gold Country" create deposits that are not consolidated, but rather randomly scattered throughout the "mass". Later when drainages cut thru the mass we find sorting and stratification that we normally see within river/stream placers.

Being able to detect "sorting" or "non sorted" helps one understand different kinds of placer deposits.
But we as humans need to understand what made this planet what it is, and that the surface of the planet is constantly changing........we live amongst natural geologic events.

I only hope the affected people and property make it through ok.......prayers for them.

After reading all the rational posts here I couldn't help but wonder how the control freaks in our society are going to act. Most likely The area will be closed and millions of dollars will be spent to help the land to "heal". Meanwhile the people effected will be ignored and forgotten. Unfortunately most locals looking to help out there neighbors will be kept out for there own "safety". Of course any mineral exploration will be shut down for years if not forever.
 

This is an awful tragedy. I work and prospect within a mile of the slide on a regular basis. The people of Oso and their volunteer fire department are great people and friends as well.

The Local communities are coming together to help with all they can, but more is needed. If you feel it in your heart that you can donate check out the Oso emergency Information page attached.

God Bless these folks, and the now 18 more that are missing.

Terrible event.

I hope they find a solution to the now mounting problem of water back-up.

We had one of these a few years back and the river ran chocolate brown for days because of it.

Mother Nature takes the prize for dumping sediment into streams and for taking lives in a flash.

All the best to all of you currently struggling through this,

I am sorry to hear of the loss of life and I hope the best for the families of all involved who are in that area and dealing with the aftermath of this tragedy.

For those interested a quick look on Google Earth of the site shows that this is not the first time that particular spot has let go. I am no geologist or soils expert but from looking at the area above and around it, it appears that there will probably be future slides there too. Life is short at best. Make sure you get the most of it.

Best of luck to them and anyone up there.
They need to get some heavy equipment, with operators, trucks and drivers, and some miners and construction workers there that know how to move dirt, and work hard.
Then they will make it fine.
