Here are some fall colors that won’t fade away. At Petrified Forest National Park in Arizona, 200-million-year-old petrified logs lie strewn across rolling clay hills. Each piece is like a giant quartz crystal. As impurities like iron and carbon oxidized, they permanently colored these ancient trees shades of red, yellow and purple. It’s a rare and beautiful sight that you’ve got to see for yourself. Photo by National Park Service.
