Re: Beach gone

Not sure where that sand is if not gone. There are certainly no new beaches being born along the southeastern coast of Lake Huron.
Like I say, I have never seen the beaches disappearing this much, over this short of time during my time.
Coincidentally this quick erosion has been taking place in conjunction with the breaking off of some of the largest sections of the ice shelf in recorded history.

BTW, there has always been lots of sand along that shoreline. Very little rock.

Always?

Re: Beach gone

Well, how many million years are we going back? Before or after the glaciers receded?
I find lots of salt water sea fossils along the shores. Urchin, coral reef, vertebrae and sometimes what looks to be a sharks tooth.
The largest salt mine in the world has miles of tunnels beneath Lake Huron.

In its current form, Lake Erie is less than 4,000 years old.

Re: Beach gone

How did so much salt get deposited in the Great Lakes region you wonder?
There are also deep salt caverns that have been used to store...who knows what type of nasty stuff. Dow Chemical might know.

Re: Beach gone

Many millions of years ago - even before the dinosaurs - during the Devonian Age it was a shallow, tropical, salt water sea.  I suppose its disappearance is our fault too.

Re: Beach gone

I don't know if it our fault.
Is it changing before our eyes?...Yes it is.

Re: Beach gone

Don't forget that many million years ago Mother Nature did her thing without the effects of the human population and the industrial world until a few years ago.
The ice carved out those lakes and left a huge deposit of salt with the evaporation and recession of frozen sea water. Once the ice thawed further north its water filled into those empty basins.
How it became fresh water, I don't know.
Maybe filtration through the forest lands.

Re: Beach gone

This circles back to Lake Erie.
If the water level is not rising as you say and sediments are being washed into that basin as I say. Where does the run off go?
It reaches sea level if not contained by locks or diverted for power generation.
Either way, the sea levels have to be increasing or the low lands surrounding Lake Erie will become flood lands.
