Road trip report: spring break at Grand Canyon

For spring break this year, I drove to the Grand Canyon and back with two sixteen-year-old girls (which meant that I did all of the driving). What was I thinking? I was thinking it might be fun. Well, it turns out I was right. I only thought about killing them once or twice; the rest of the time, we were all too busy taking pictures and laughing at each others' lame jokes. The photo highlights (and all of the hundreds of other pictures we took) can be found at my Flickr site.

Our traveling roadshow:


Day 1, Tuesday: Boulder, CO, to Blanding, UT (440 miles): via I-70 and US-191

We hit the road with a box full of canned goods (ravioli, green beans, corn, peaches, pineapple, etc.), plenty of bottled water, a huge music selection (ran the gamut from Kanye West to Madonna to Paul Oakenfold to AC/DC to the Backstreet Boys), and other assorted supplies (especially pretzels).

The first day was the biggest, mileage-wise; we hoofed it all the way out to Utah and then a good ways south, with room for sightseeing stops on the way. We stopped in Glenwood Canyon for a lovely picnic lunch of cold canned ravioli and green beans. At a scenic rest area off I-70 in Utah, we took another break, took lots more pictures, and my gravity-defying little sister topped out on a picnic shelter and later somersaulted over a concrete retaining wall. (Actually, she says, she was attempting to vault it at a run, but her foot slipped, and she recovered by throwing her shoulder down and going into a roll. I wasn't paying very close attention, so from my perspective it looked cooler than that sounds.)

Farther down the road, just north of Moab, we drove through Arches National Park, which was gorgeous. That night, somewhere out on the open highway north of our destination, we stopped on the side of the road to look at the stars and debated over what was or wasn't the Big Dipper or Little Dipper.

Day 2, Wednesday: Blanding, UT, to Flagstaff, AZ (262 miles): via UT-95, UT-261, US-163, US-160, and US-89

We headed west from Blanding to Natural Bridges National Monument. The drive there was beautiful: blue sky, bright sun, rolling hills, towering roadcuts, surprising vistas. The park itself was chock full of picturesque sandstone. We drove the nine-mile loop road, stopped to look and take pictures at every overlook, did some meandering on foot.

Then we headed south for the Arizona border. We knew that we were coming up to a small section of road called Moki Dugway; the park ranger at Natural Bridges said it was a series of switchbacks, descending more than 1000 feet over 3 miles of road surface. Then we came to a pull-off, beyond which the road disappeared over a rise. We stopped and walked out to the edge of a sandstone overlook, where I had a monumental "whooooaaaaaaa" moment as the view opened up in front of us. Far below, the highway zigzagged off into the distance across the wide country. Moki Dugway, as we discovered when we finally got back in the car and continued down the road, is a narrow, side-winding gravel lane that twists back and back on itself to eke down the side of Cedar Mesa. I drove slowly, enjoying the view, and the girls screamed like it was an amusement park ride around every hairpin curve. A little further down the highway, just north of Mexican Hat, Utah, we did some off-roading near Mexican Hat Rock. I was feeling adventurous, the girls were yelling encouragement in my ear, and I went for some of the more exciting tracks. My Subaru Forester handled it all with aplomb; I love my car.

North of the Utah-Arizona border, US-163 crosses Monument Pass; from a distance, this view struck me as particularly iconic of the great American Southwest. Late in the afternoon we drove into Sunset Crater National Monument. It was pretty, but not terribly exciting or spectacular. We had fun clambering through a lava field.

Dinner was in Flagstaff, at a restaurant called Dara Thai that served up delicious and spicy Thai cuisine. Highly recommended!

Day 3, Thursday: Flagstaff, AZ, to Kayenta, AZ (230 miles): via US-180, AZ-64, and US-160

Once again, we were blessed with warm, sunny weather. We cut northwest from Flagstaff through the mountains, which was a pretty drive, and then continued northward to Grand Canyon National Park. We visited Mather Point and Yavapai Point, then did a picnic lunch in the parking lot at the park headquarters. From there we left the car for the shuttle buses, and rode up to Hermit's Rest, with a few stops at overlooks along the way. We provided our own additional entertainment by engaging in bizarre arguments (how to best conduct and cover up a mob hit) and pointless ruminations ("if my leg muscles could speak, what would they say?"), as usual, at a volume certain to be overheard by other tourists. Returning to the car, we drove eastward along Desert View Drive on our way out of the park, with plenty more scenic overlooks and lots of photos along the way. We made one more stop outside the park, at the Little Colorado Gorge, where we hiked in a little ways from the road and went venturing off the beaten path.

In Kayenta, the hotel desk clerk's dinner recommendation was a small local place called the Blue Coffee Pot. There, we discovered a nice family atmosphere and a down-home-style menu that featured Navajo dishes and other southwestern fare.

Days 4-6, Friday-Sunday: Kayenta, AZ, to Gunnison, CO (317 miles), and Gunnison to Boulder (212 miles): via US-160, US-491, CO-145, CO-62, US-550, US-50, and US-285

On Friday we headed for familiar territory. We pulled off the road at Four Corners, intending to stop and take a couple of pictures, but they wanted to charge us $3 admission per person, so we got right back on the road and kept going. Lunch was another canned picnic, parked roadside amidst the snowbanks, somewhere in the mountains of southwest Colorado. Over the course of the afternoon we played in the snow, complained at other drivers riding their brakes downhill from the mountain passes, and ate lots of pretzels. Towards evening, we made a little detour off US-50 west of Gunnison, up a little dirt track called Alpine Plateau Road No. 867. Thanks to the tire tracks worn into the mud and snowpack, and the hefty snowbanks to either side of the road, I had fun rumbling up and down the hills and sliding around turns. (No sarcasm, either -- I love my car!)

Friday night my parents rolled into Gunnison, a couple of hours after we did; on Saturday we went to the local climbing competition, which my little sister competed in and my dad helped run. We also hung out some with friends from the Colorado-New Mexico region who were in town for the same competition.

Sunday we drove home. We pulled off at Kenosha Pass on US-285, and went hiking a little ways into the woods up another mud road. Then, while my parents wandered around the parking area with the dog, I took the girls in the Subaru for a spin up the same mud road. My car came back muddy; I was duly pleased. We did lunch at Coney Island, a hot-dog-shaped hot dog stand tucked away among the evergreens just off US-285 east of Bailey, Colorado.

The technological singularity: future or fantasy?

Over the weekend, I read this fascinating series of articles in the June 2008 issue of IEEE Spectrum, addressing the concept of the "technological singularity" which some say will happen by the year 2030. Spectrum executive editor Glenn Zorpette describes it thus:

"The singularity is supposed to begin shortly after engineers build the first computer with greater-than-human intelligence. That achievement will trigger a series of cycles in which superintelligent machines beget even smarter machine progeny, going from generation to generation in weeks or days rather than decades or years. The availability of all that cheap, mass-­produced brilliance will spark explosive economic growth, an unending, hypersonic, tech­no­industrial rampage that by comparison will make the Industrial Revolution look like a bingo game." (Full article >>)

Some believe that this singularity will lead, in short order, to a kind of technological rapture. One of the skeptics, science journalist John Horgan, describes this view flippantly, but not inaccurately:

"Like paradise, technological singularity comes in many versions, but most involve bionic brain boosting. At first, we'll become cyborgs, as stupendously powerful brain chips soup up our perception, memory, and intelligence and maybe even eliminate the need for annoying TV remotes. Eventually, we will abandon our flesh-and-blood selves entirely and upload our digitized psyches into computers. We will then dwell happily forever in cyberspace where, to paraphrase Woody Allen, we'll never need to look for a parking space... Notably, singularity enthusiasts tend to be computer specialists, such as the author and retired computer scientist Vernor Vinge... and the entrepreneur Ray Kurzweil. Intoxicated by the explosive progress of information technologies captured by Moore's Law, such singularitarians foresee a 'merger of biological and nonbiological intelligence,' as Kurzweil puts it, that will culminate in 'immortal software-based humans.' It will happen not within a millennium, or a century, but no later than 2030, according to Vinge... Kurzweil says he has adopted an antiaging regimen so that he'll 'live long enough to live forever.'" (Full article >>)

Researcher John Casti, however, foresees the singularity going in the opposite direction:

"I think it's scientifically and philosophically on sound footing. The only real issue for me is the time frame over which the singularity will unfold. [The singularity represents] the end of the supremacy of Homo sapiens as the dominant species on planet Earth. At that point a new species appears, and humans and machines will go their separate ways, not merge one with the other. I do not believe this necessarily implies a malevolent machine takeover; rather, machines will become increasingly uninterested in human affairs just as we are uninterested in the affairs of ants or bees. But it's more likely than not in my view that the two species will comfortably and more or less peacefully coexist -- unless human interests start to interfere with those of the machines." (Full article >>)

Here, then, is a view of a different kind of singularity (which is, in my opinion, a more plausible one), as proposed by MIT robotics professor Rodney Brooks:

"My own view is that things will unfold very differently... an artificial intelligence could evolve in a much different way. In particular, I don't think there is going to be one single sudden technological 'big bang' that springs [a human-level artificial intelligence, or AI] into 'life.' Starting with the mildly intelligent systems we have today, machines will become gradually more intelligent, generation by generation. The singularity will be a period, not an event.

"This period will encompass a time when we will invent, perfect, and deploy, in fits and starts, ever more capable systems, driven not by the imperative of the singularity itself but by the usual economic and sociological forces. Eventually, we will create truly artificial intelligences, with cognition and consciousness recognizably similar to our own. I have no idea how, exactly, this creation will come about. I also don't know when it will happen, although I strongly suspect it won't happen before 2030, the year that some singularitarians predict.

"But I expect the [AIs] of the future -- embodied, for example, as robots that will roam our homes and workplaces -- to emerge gradually and symbiotically with our society. At the same time, we humans will transform ourselves. We will incorporate a wide range of advanced sensory devices and prosthetics to enhance our bodies. As our machines become more like us, we will become more like them." (Full article >>)

The questions are many; the speculation runs rampant. Will machines ever be as smart as humans? Will they ever achieve "consciousness"? Will they be our helpers, our caretakers, our overseers? Eventually, time will tell -- assuming that the human race doesn't first undergo some kind of cataclysmic event (e.g., an Andromeda strain, a nuclear holocaust, extraterrestrial enslavement, the Biblical end of days, etc.).
