     When The Rocky Mountains moved upwards, the pushed the overly sedimentary rock layer to the side,
creating complex folds.

     Some of these folds are nicely displayed in central Montana, adjacent to the Rocky Mountains.



Here is an unmarked view of the folds.  Vegetation, agriculture, and river drainage tend to mask some of the
fold structures.


   
zooming in and highlight the fold structures with yellow lines using the Google Earth measuring tool



Here is an unmarked oblique view of the folds.


Carefully marking the folds using the measuring tool as a drawing device greatly enhances the fold pattern.

 

Here is another unmarked view of the folds.


the same area as the above view, but marked

now the same view with the structures delineated
