Standing high above a valley in the Petrified Forest National Park in Arizona 200 million years ago winged dinosaurs glided over the lush river basins and forest here. Giant amphibians and armored fish populated the water ways. Some of the earliest dinosaurs roamed the grasslands in herds. Volcanic lava destroyed the forest, and the remains were embedded into sediment comprised of volcanic ash and water. The land is still dotted with the crystallized remains of a nearby forest. What was once wood pulp is now beautifully colored quartz. The Petrified Forest chronicles more than 13,000 years of human history within the park with ancient dwelling, fossils and artifacts. The northern part of the park is home to The Painted Desert, badlands composed of stratified layers of erodible siltstone, mudstone, and shale. The varied pigmentation is from the iron and magnesium compounds found within the rock layers. The colors, patterns and textures are incredible. Knowing the history, you can't help but be mesmerized by everything you see and a bit in awe with every step you take. Standing there with my camera and tripod I'd often just try to imagine where I really was, not in geographic proximity but in time. Wondering where this will all be in the next 200 million years. A couple weeks ago I was in the cool, lush greens of Colorado and today the monsoon drenched badlands of the Sonoran Desert. Such is the life "wandering on the edge".
