As expected, Obama proclaims Colorado's Chimney Rock a NMon
A thousand years ago, the ancestors of modern Pueblo Indians were among the ancient people who watched the sky.
They built a village near an extraordinary rock formation in southwest Colorado that captures the rare Lunar Standstill.
Today it is called Chimney Rock, a sprawling archaeological site covering nearly 5,000 acres in San Juan National Forest. President Obama gave it a National Monument designation last week, his third and the nation’s 103rd overall.
