Rockslide/Tsunami at Antelope Point

[ScottF]

Can anyone report on the rockslide/tsunami at AP?

You mean the one in June?

If so search back on this forum - it was widely talked about

Here’s the remains - where Warm Creek meets the main channel

I understand there was a major rockslide near AP yesterday that produced substantial waves through the Antelope Point Marina damaging a number of boats. But I only have 2nd or 3rd hand info.

My money is a wake boat or one of those super cruisers came through.

Ok never mind

I’d like to hear about that too!

Here is a photo, immediately West of the old AP ramp. That's a lot of rock into the lake. Photo courtesy of Doug/Pegasus.

Holy smokes! That’s huge. That wipes out the bottom of the secondary cart path they’d cut.

I’m not sure we know exactly where this occurred yet, what did the OP mean by the “old“ ramp? As far as I know there are two ramps in that area, the public one and the valet/private one. Not sure what he means by “old“?

I should have been more clear with "old ramp". I'm referring to the walking path/cart path that, until recently, went from the AP parking/store/rest rooms down to the floating restaurant/store. This was the access all people and carts used to get down to the docks before the lake level dropped. You can see this path on the left of the photo.

we have video from all sides of our houseboat. Did some damage on our boat and I assume many others. Here is a clip showing the tsunami wave going down the canyon wall. The amplitude is not crazy but the frequency is.

here is another view out the side of our boat of our neighbor getting rocked.

Wow

5:30 in the morning? There’s a lot of folks staying in boats in slips, and that’s a rude awakening.

 

[Shredhook]

imagine waking up to that!!!

 

[Michael Pyle]

maybe someone else can analyze the video but that wave looks at least 150ft peak to peak. The wavelength is crazy. height seems 3-2ft

Thank you , I get it now, thanks for helping me understand. Sometimes I suffer from CBCD (chronic brain cell deficiency)

That's a big chunk of rock!!!!!

I wonder if the excavator went down with it. When we were there 3 weeks ago they left it down there overnight.

Makes you wonder, I would think that excavator would have a rock hammer attachment to facilitate the earthworks. If so, how much that hammer vibration attributed to this?

Now deep water salvage has two reasons to come to Powell. Retrieve "Knockers" and an excavator!! Both have a lot of fuel and oil on board!!
