Description: Gart, Callander, Perthshire. A glacial erratic. An exhumed ice-scoured boulder of Old Red Sandstone conglomerate occurring in outwash gravels of the Loch Lomond Readvance glacier which terminated in the vicinity. See also D03326 for a close-up. The boulder would have been deposited at the ice front of the retreating glaciers. The outwash gravels are the deposits formed on an outwash plain, the drainage area immediately in front of an ice-sheet where there is a large number of temporary constantly shifting streams that carry a great deal of sediment. The deposits consist of irregularly stratified drift from very coarse gravels to fine clay further out from the ice front.
