With the melting of the ice (once a kilometre or more thick), the sea-level rose as much as 30 metres, flowing over the bank (the trig point on it stands at 29 metres) and then gradually eroding it into the present-day steep slope as the sea-level fell. The final act of the sea, some 6,000 years ago, was to deposit a series of four gravel ridges close to the foot of the bank. There was once (1920s to 1930s and perhaps earlier) a nine-hole golf course on the ground between the bank and the road here. Even today, one occasionally sees a golfer practising his swing and knocking balls about, while passing motorists keep a very wary eye open for them!
Much of the above came from the booklet 'A Guide to the Geology of Islay' by Alex Maltman and others. Available to purchase at the INHT Centre.
