From the discussion in the Seek The Peak trail thread I learned about the massive avalanche that occurred in the Ammonoosuc Ravine in late February 2010.

First blog post with photos here: Blog Post (http://whitemountainsojourn.blogspot.com/2010/03/mt-washington-lakes-of-clouds-3-7-10-in.html)

Search his later posts for more photos as the debris continues to melt out.

Thanks to Brad's web cam image archive I was able to track down some before and after images of the slide path from across the valley. If somebody can narrow down the date using Brad's archive please post it here.

Please feel free to post more photos / information about the slide here.

Bill, could you put an arrow on the after photo showing where it was? I'm not seeing it. Thanks!

Wow, that's amazing. I've heard about this slide, but seeing the before and after webcam images and reading the blog post brings it to life. Is the Ammy trail completely shredded? I'll try to do some homework and post whatever I find.

Here's a link to a TR from May that I just found:

Looks like it was a near miss and the trail itself is still in good shape. I'd love to hear more from anyone who has hiked over there this spring/summer!

If you don't know where to look it is easy to miss.

In the "after" photo come down from the summit of MWN and just below the cloud line there is a large white patch at the confluence of the two gullies. In the "before" photo it is a much smaller patch.

It also looks like that far left ravine off Jefferson has a slide path running well below tree line, but I don't know if that is new.

I'll be up the Ammy in the next week and will report back.

Ah, now I see it. Thanks Bill.

Wow...jeremy's recent pic from the trail really shows it well. I've been lookinh at this slide on forums for a few months...but never thought to look at it on the webcams. Bill...great spot on the jefferson slide too...worth comparing to last year to see if it is really recent...

First signs of the avalanche begin at 3,300 feet. The trail was slightly hit in one spot.

The only visible evidence of the slide was a hundred yard stretch along the Ammo where it ran past the trail down the drainage and a short section where it crossed the trail near 3,300 feet. Above that point the trail enters a different drainage and the slide path is no longer visible.

Photos near the 3,300 foot level:
