closer

According to the National Park Service, describing the Sheep Rock Unit at John Day Fossil Beds National Monument:

The predominant exposures of green rock seen on Sheep Rock are a multitude of reworked layers of volcanic ash. The rich green color of the claystone was caused by chemical weathering of a mineral called celadonite. This happened millions of years ago as water moved through the alkaline ash beds under high pressure.

Wilderness is not a luxury but a necessity of the human spirit, and as vital to our lives as water and good bread. A civilization which destroys what little remains of the wild, the spare, the original, is cutting itself off from its origins and betraying the principle of civilization itself.

    • You were here with me (virtually speaking, of course!) I split this hike up into 4 posts (3 previous and you might enjoy the newer one after this where I went a bit crazy?). I was utterly enthralled with this section of the painted hills. I’m so glad you got to visit it. You’re reminding me that I really, really want to go back and explore some more.
