[QUOTE="user 4386, post: 647968, member: 4386"] No, there is no way that water can transport boulders of that size (some so big that it is difficult to climb on top of them). However there are other features that tell us they are glacial. If you go to the reservoir at Knowsley East in dry years (low water) you will see "glacial pavements" of highly polished rock formed by the ice moving across the rock surface. And "chatter marks" and "glacial striations" formed by rocks embedded in the base of the ice scratching the polished rock surface - and of course the marks are linear and all parallel because the ice was moving in a constant direction. This article has good photos of these features at Knowsley East. [URL unfurl="true"]https://weekendgeology.com/2018/04/26/lake-eppalock/[/URL] [/QUOTE]
