Polygon highlights a single flatiron in a tilted region composed of numerous flatirons (some small with narrow, pointed tips and some large with broad, rounded tips) on the northeastern flank of the Wind River Mountains uplift in Wyoming. Rotate the view so that you are looking directly down on the flatiron with north at the top. Which direction are the rock layers dipping?

Explanation:

The rock layers dip in the direction water will flow when poured down on the flatiron which is the northeast direction.

see the picture below for more understanding

In addition, use google earth, search wind river mountains

use a ruler to draw a line that runs northeast and southwest direction

save and right-click on the path you have saved and

choose "show elevation profile'

this will confirm the northeast direction and the dip direction
