Maya had four days off in a row last weekend so we decided to make one of our big planned trips to another part of Arizona. He decided to go north to see what we could see in the Flagstaff area. On Friday, this was exactly one week ago, we dropped Asher off at the pet resort and sped on up I-17. Interestingly, though I-17 is an “interstate,” it only runs from Phoenix to Flagstaff. That makes it more of an intrastate highway… We did hit a little bit a slowdown again. That’s 0 for 3 for smooth travel on I-17. We had intended to get an early start, but per our usual, we didn’t we got lunch just north of Phoenix.The drive was fairly amazing. It’s only 150 miles so you would think that things could change that much. However, the route rises over 5,000 feet from Phoenix’s 1,092 to Flagstaff’s 6,905 feet above sea level. The terrain in the same: flat plains broken by low hills and the occasional mountain of shattered boulders. The thing the really changes is the flora. Just outside on the manicured and watered lawns of Phoenix metro the terrain is once again the natural desert. Saguaro cacti dominate the hills. There are smaller, shrubby plants too. Then all of a sudden there are no saguaros but lots of this hearty tree called a paloverde. It’s green, as the name suggests, so it doesn’t need as large a left to get it’s photosynthesis on. It looks something like a very feathery willow. This goes in a while then you dip down into Verde Valley, going below 4,000 for the first time in miles. There are actual deciduous trees in the valley. They are in fall color as you might expect for this time of year. Next you start to climb again and the broken hills are covered in yellow grasses and pine trees. Yes! Pine trees! Whole hillsides of them! It actually strongly reminded us of the upper peninsula of Michigan. We didn’t know how much we had been missing real trees until we saw them again.
We drove right on past Flagstaff on that fist day. We headed east along I-40 to Meteor Crater. It’s about 30 miles from the city. This is also known as Barringer Crater after the man who championed it as a meteor crater. Previous observers had suggested a volcanic origin. There are a lot of volcanoes in the area. The highest point in Arizona is Humphreys Peak, just north of Flagstaff. It’s an extinct volcano. What Barringer kept pointing out is that aside from the crater itself there was no evidence for volcanic activity right in that spot. Also, the little bits of iron laying around everywhere were a big clue. His interests in the crater started as purely economic. As a mining engineer, he hoped to find the giant chunk of iron that had made the crater and thus mine it. He didn’t find it (as it was mostly vaporized in the impact), but by the time he gave up looking he had become dedicated to proving that it was indeed an impact crater, or astrobleme, as nerds like Matt like to say. He was largely successful and his work was instrumental in identifying craters as impacts sites on other bodies like the moon and Mars.
Seeing the crater is a little hard to describe. Very memorable for us is how quiet it was there. It’s a long way from anything so there is almost no city, car or animal noise. Quite surreal. On one hand the crater is amazingly simple. It’s just a big hole in the ground. That’s it. There is nothing else to see besides the hole. It is a big hole, but still just a hole. On the other hand is all the stuff about how it formed, about other impact craters on Earth that are less well-preserved, about the effects of impacts like, um… the end of about half of all life 65 Ma (million years ago). In that light the crater is not so impressive for what it is, but for all that it represents. It practically resonates with significance. Matt can now cross off a mid-level item from his life's to do list.
Why do space rocks taste better than Earth rocks? Because they’re a little meteor! If you like that joke, you can thank Futurama. In fact, you can thank Futurama by buying the new DVD movie Bender’s Game. We thought it was the best Futurama yet since the show ended.
