Soil

[Mad Scientist]

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.

the simplest one would be to look for aquatic vegetation. algae in particular. If thats there then the location was inundated for some time.
