Powder River Pass Eclipse
Not every lunar eclipse is the same. Each one varies depending on which part of Earth’s shadow (called the umbra) that the moon passes through. Atmospheric conditions on Earth also influence the view. Lingering exhaust from the massive volcanic eruption in Tonga in January helped make this eclipse darker and redder than usual. In Wyoming, totality started during twilight. The extra light revealed more details in the landscape. Then after twilight ended, thousands of stars came out, along with stripes of green airglow. A dark sky and a full moon, normally enemies of each other, were seen together for just a few minutes before normal moonlight returned.
While the lower slopes of the Bighorn Mountains are now a vibrant green, up here at Powder River Pass, winter is still hanging on. Nearly 10,000 feet above sea level, temperatures still drop below freezing at night even in mid-May.
