Painted Hills 5
John Day Fossil Beds National Monument,Oregon.
The black soil is lignite that was vegetative matter that grew along the floodplain. The grey coloring is mudstone, siltstone, and shale.The red coloring is laterite soil that formed by floodplain deposits when the area was warm and humid. An abundance of fossil remains of early horses, camels, and rhinoceroses in the Painted Hills unit makes the area particularly important to vertebrate paleontologists. (Wikipedia)
