Painted Hills, in the northwest United States, is one of the three units of the John Day Fossil Beds National Monument, located in Wheeler County, Oregon. It totals 3,132 acres and is located 9 miles northwest of Mitchell, Oregon. The Painted Hills are listed as one of the Seven Wonders of Oregon. Painted Hills is named after the colorful layers of its hills corresponding to various geological eras, formed when the area was an ancient river floodplain. 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. ------------------------------ Music: 1 zero-project - - Metamorphosis 00:00 2 zero-project - - The crossroads of change 07:53 3 zero-project - - The preparation 12:07 4 zero-project - - Path to innocence 16:06 5 zero-project - - The call of the desert 21:39 Music Albums "Metamorphosis" CC BY 3.0 www.zero-project.gr
