Ruby Mountains, Lamoille Canyon
An amazing geologic feature seen in a cross section of the Lamoille Canyon wall cut by glaciers. The feature is easily 50' tall. The canyon wall is metamorphic either mixed at the time of the original mud disposition or infiltrated after or during the metamorphic processess. It is hard to imagine the pressures and processes required to bend and twist rock as if it were taffy or a marble cake mix. It looks like someone put a spoon in and twisted it clockwise 125 degrees. This is in the middle of a 500 or 1000' cliff wall.
