Cultures all over the world have marked the passage of the seasons in many ways. In the Southwest, the solstices and equinoxes have often been tracked by watching the sun on the horizon, on particular landmarks, or on the faces of rock.
Wildfires in the West have gotten bigger and more intense over the last 40 years. The amount of land area burned has increased six-fold. On the Colorado Plateau, fires strip away plant life and open up a window to the past, revealing information from thousands of years ago.
The spring equinox is one of two days a year when the equator lines up with the center of the sun, creating a balance of day and night. Historically – for many indigenous people of the world – this celestial event marks a time for renewal, emergence of life and planting of crops.
