The Painted Hills are one of Oregon's Seven Wonders
The Painted Hills are named for their delicately coloured stratifications in the soil, with stripes of vibrant yellow, lavender, crimson, gold, black, red, and orange. The claystone layers differ with changing light and moisture levels, so the hills' hues vary depending on the weather and moisture levels. The seasons can also radically change the look of the Painted Hills. In spring, yellow wildflowers may grow, and in winter, snow can blanket the hills, concealing the vibrant hues.
The Painted Hills are one of three units that comprise the John Day Fossil Beds National Monument, along with Sheep Rock and Clarno. The Painted Hills are by far the most popular of the three units. The site is rich in fossils, with fossils of plants and trees and animals like early horses, camels, rhinoceroses, and saber-toothed cats. The fossils have contributed to advancing our understanding of the evolution of many plants and animals.
The hills began to form 35 million years ago when pumice and ash from volcanic eruptions in the Cascade Mountains travelled 100 miles east and settled over the area. The ash turned into soil through compaction and cementation, and with weathering, the exterior surfaces of the hills became clay. The colours of the hills come from the combination of various elements, including aluminium, silicon, iron, and manganese, which arrived with the initial ash fall. The alternating red and tan layers are the result of cycling climate conditions, with warm and wet periods followed by cool and dry periods.
The Painted Hills are open year-round for visitors, with several well-marked trails. Visitors are encouraged to take a pledge to stay on the trails to avoid disrupting the natural mineral layers.

The hills are a geologic site in Wheeler County, Oregon
The Painted Hills are a geologic site in Wheeler County, Oregon, and are listed as one of the Seven Wonders of Oregon. The hills are characterised by their layers of vibrant colours, including red, yellow, gold, black, orange, brown, blue, green, lavender, and crimson. The different colours are due to the soil being composed of a combination of mudstone, siltstone, shale, and lignite. The colours of the Painted Hills are also influenced by the light and moisture levels, with tones and hues appearing differently at various times of the day and year.
The Painted Hills are located in the heart of central Oregon, and are one of the three units that comprise the John Day Fossil Beds National Monument, along with Sheep Rock and Clarno. The hills cover a total area of 3,132 acres (12.67 km2) and are situated 9 miles (14 km) northwest of Mitchell, Oregon. The site is open year-round and has several well-marked trails for visitors to explore.
The Painted Hills were formed approximately 35 million years ago when pumice and ash from volcanic eruptions in the Cascade Mountains travelled 100 miles east and settled over the area. Over time, the ash underwent oxidation, compaction, and cementation, transforming into soil and eventually hard claystone layers. The original light-coloured ash mixed with other elements to form the minerals that give the hills their distinctive colours. The different layers of colours, or stratigraphy, can be attributed to cycling periods of wet and dry climate conditions, with the region transitioning from a warm and humid climate to cooler and drier conditions over millions of years.
The Painted Hills offer a glimpse into the ancient history of the region, with fossils of early horses, camels, and rhinoceroses discovered in the area. The hills are also home to a diverse range of wildlife, including birds, elk, deer, cougars, beaver, otter, mink, raccoons, coyotes, bats, and badgers.
Visiting the Painted Hills is a popular activity, with people travelling from nearby towns such as Bend, Redmond, and Prineville to explore the site. The area offers easy short trails, such as the Painted Cove Trail, and panoramic views, making it a unique and captivating destination for hikers and nature enthusiasts.

The Painted Hills are a part of the John Day Fossil Beds National Monument
The Painted Hills in Oregon are a stunning natural wonder, and one of three units that make up the John Day Fossil Beds National Monument. The Painted Hills are located in Wheeler County, in the heart of central Oregon, and are listed as one of the Seven Wonders of Oregon. The site covers 3,132 acres and is situated 9 miles northwest of Mitchell, Oregon.
The Painted Hills are aptly named for their vibrant, colourful stripes, with deep reds, brilliant yellows, rusty copper blues, pastel greens, golds, blacks, oranges and browns. These colours are best seen in the late afternoon when the light is ideal for photography. The hues of the hills change with the light and moisture levels, and the seasons also have a transformative effect. Spring brings wildflowers, while winter snow conceals the vibrant hues until it melts, revealing stripes of gold and red.
The hills are a geologist's dream, with layers of rock and soil revealing millions of years of history. The different colours are due to the unique composition of the soil, which includes mudstone, siltstone, shale and lignite. The colours are derived from a combination of elements, including aluminium, silicon, iron, magnesium, manganese, sodium, calcium, phosphorus, titanium, potassium, oxygen and hydrogen. These elements arrived with the initial ash fall from ancient volcanic eruptions. The oxidation of the ash, compaction and cementation over time turned the ash into the claystone layers seen today.
The Painted Hills are a popular attraction for visitors, with well-marked trails and boardwalks offering easy access to explore the area. Visitors are encouraged to stay on the trails to protect the fragile landscape. The area is also rich in fossils, with leaf fossils and fossilised remains of early horses, camels and rhinoceroses discovered in the area. The fossils provide valuable insights into the evolution of plants and animals, contributing significantly to our understanding of the region's ancient history.

The hills get their name from their delicately coloured stratifications
The Painted Hills in Oregon are considered one of the Seven Wonders of Oregon. The hills are located in the heart of central Oregon, in Wheeler County, and are a part of the John Day Fossil Beds National Monument, which consists of three separate units. The Painted Hills are by far the most popular of the three units. The other two units are Sheep Rock and Clarno, which features Mars-like pillars formed by waterfalls and volcanic sludge.
The Painted Hills are a geologic site, covering 3,132 acres. They are located 9 miles northwest of Mitchell, Oregon. The hills are named after their delicately coloured stratifications, with stripes of vibrant yellow, lavender, crimson, gold, black, red, orange, brown, rusty copper blue, and pastel green. The delicate layers of colour in the soil are due to the cycling periods of wet and dry climate conditions associated with the transition from the Eocene epoch to the cooler, more temperate Oligocene epoch. The different layers of colours are due to the soil being composed of a combination of mudstone, siltstone, shale and lignite. The colours of the Painted Hills come from the combination of elements, including aluminium, silicon, iron, magnesium, manganese, sodium, calcium, phosphorus, titanium, potassium, oxygen, and hydrogen.
The Painted Hills began to form 35 million years ago when pumice and ash from volcanic eruptions in the Cascade Mountains travelled 100 miles east and settled over the area. Over time, the ash on the surface oxidised, and it was buried under new layers and deposits, turning into soil by compaction and cementation. With further weathering, the exterior surfaces of the Painted Hills turned into clay. Now, they are primarily made of hard claystone layers. The darker, black soil is lignite that was once vegetative matter that grew along the floodplain. The grey colouring is due to mudstone, siltstone, and shale. The black marks on the hills are coloured by manganese oxide.
The Painted Hills are best viewed in the late afternoon, when the yellows, golds, blacks, and reds are beautifully lit for photography. The tones and hues visible in the hills change drastically depending on the light and moisture levels. The seasons can also radically alter the appearance of the hills. Spring brings yellow wildflowers, while winter coats the hills in white, hiding the vibrant hues until the snow melts, revealing stripes of gold and red.
