Possible Late Ice Age Talus at Palmer Lake Road Cut

My first thought was that this exposure was a mixed up mess of glacial drift - that is a deposit made directly by glacial ice.




However, the light colored, non rocky unit was not compact and readily crumbled in my hand to a loose powder of fine silt.


My take on this road cute was it was a talus deposit from the steep cliffs above overlain by a glacial lake deposit and then capped with yet another talus unit from rock fall from the cliffs above.
