Mad Scientist Posted November 25, 2010 Share Posted November 25, 2010 (edited) For a glacial study i am undertaking i want to prove a hypothesis that a Ribbon lake once occupied a valley because it was dammed at the end by morraine. For this i will be using an ogre too dig down into the soil on the valley floor. Does anyone no what sort of things i should be looking for in the soil that will prove my Hypothesis. Any info would be greatly appreciated. Edited November 25, 2010 by Mad Scientist Link to comment Share on other sites More sharing options...
