Along the beaches of Scotland the waves were up to six meters (20 feet) high. Geologists have discovered a ravaged Stone-Age site there.

Shouldn't evidence of that tsunami still be present in modern England and Scotland?
Has erosion altered the landscape that much in 8100 years to erase all evidence of deposits?

I've read that there is still evidence...I just can't find where I read it.

Sea level may have been lower then...some of the evidence (scouring, erosion scars, etc) may be underwater at present.
