The characteristic coloration of Sedona’s geological formations is primarily due to the presence of iron oxide. Over millions of years, iron minerals within the sandstone layers underwent oxidation, a chemical process akin to rusting, resulting in a coating that imparts the distinctive hue. The specific shade, ranging from vibrant scarlet to subtle terracotta, depends on the concentration and type of iron oxide present.
This visually striking feature contributes significantly to the region’s aesthetic appeal, drawing tourists and artists alike. The dramatic landscapes have fostered a thriving tourism industry, boosting the local economy. Historically, the unique geological formations have held spiritual significance for Native American tribes, who recognized the power and beauty of the land.
