I have not found anything in English about the geology
of these hills. However, like the Painted Desert of
Arizona, the colors likely represent deeply oxidized fossil
soils (paleosols) (oranges and yellows) interbedded
with layers of reduced / unoxidized sediment, possibly
either lake or fluvial deposits.
For the Google Earth fans, the coordinates are
latitude 38.9546, longitude 100.0744. Just insert
“ 38.9546, 100.0744 ” into Google Earth search .
If anyone knows where I might find some information
about their geology, I would appreciate knowing where
it can be found.
