Wupatki National Monument, Flagstaff

I was on a roap trip with my son and my parents to Colorado. Along the way we would stop and see the sites. They told me of a crater that was along the way that I could not find on the map. However, I saw "Sunset Crater". Sounded interesting, so we headed north of Flagstaff. I was totally amazed by what I saw. I thought as though I was on another planet. Hills made of black lava surround you as you take the leisurly drive towards the crater. You get a sense of how old these formations are and of it's violent history. I thought the road would take us all the way to the crater but it stopped. I'm sure you could probably hike from there. I had my parents with me so we stuck to the car. Great side-trip, and I'd like to share it with my husband some day (perhaps on our way to the Grand Canyon?
