GCNRA Wandering: Andy Miller Flats


Still right here.
Jan 17, 2012
On Sunday and Monday of President's Day weekend I explored some canyons near Andy Miller Flats in Glen Canyon National Recreation Area. I awoke at 5:30AM on Sunday, hit the road by 6:00, and witnessed a brilliant sunrise while driving on Highway 24. I had to slow several times for cows crossing Highway 95. Good thing I'd spent a couple of hours the previous day replacing the front brake rotors on the Grand Cherokee. Between the Dirty Devil and Colorado River bridges, I turned onto the Flint Trail/NPS633, heading roughly east. The road had been graded since my last time there four months ago and I made great time on the dirt. It was only five miles as the raven flies, but three times that on the road, to where I planned to start the day's hike.

My intention was to explore some canyons in the area to try to discover rock art, and doing so among some fine scenery was a welcome bonus. After last October's trip I got a feel for where the area's rock art is situated, but I already knew beforehand the location of all the sites I saw during that trip. This time I simply wanted to wander and hoped to find something new. The day started out overcast, which led to me leaving my hat in the Jeep--and an eventual sunburn. I hiked only a short distance before the canyon began to deepen and I started inspecting all the cliffs and overhangs. A short while later I encountered a small overhanging cliff that had quite a few relics underneath. There were two large broken metates and several smaller fragments, broken pottery pieces, and a shload of lithic flakes. I continued hiking around the canyon rim and found a couple more such sites, but none as significant as that first. I was thoroughly enjoying the views down into the canyon and the snow-covered Henry Mountains towering over the desert.

As I neared the point where I had planned on turning around and heading back to the Jeep, I scanned the canyon below with binoculars. I'd marked a spot in the GPS that I noticed in Google Earth that seemed a likely spot for rock art, but I was still surprised when I actually could see some red pictographs there! I was about a third of a mile away and several hundred feet higher than the shallow alcove. There wasn't a visible route leading to the canyon bottom from where I stood, so I began to zig-zag along and down the many ledges until, after one final steep scramble, I found myself standing in the watercourse. From there it was a short hike downcanyon to the alcove and the rock art. In addition to the rock art were some ruined structures, including a few slab-lined storage cists, and a tall stack of rocks that somebody had built to access a ledge above the alcove floor. There were also a couple of inscriptions.

It was getting later in the day and my legs were tired, so after viewing the rock art alcove I took a pretty direct route back to the Jeep where the thermometer read 69 degrees. And it felt it! The sky had cleared and the latter half of the day had been wonderfully warm and sunny. I'd hiked the last quarter-mile with my backpack slung over my shoulder to let the sweat on my back dry. The total hiking distance for the day was 6.7 miles. I drove down the road to one of the few nearby spots where I could get far enough off the road to camp, and there I found an unoccupied 60 series Land Cruiser. I didn't know if the owner was just out hiking or if the vehicle was being left there for an extended time, so I picked a spot a couple hundred feet away and sat in my chair reading a magazine and waiting for dinner time. Eventually the Toyota's owner showed up on foot and we struck up a conversation--he was from Grand Junction and had been out for a hike to the south. We inquired about each other's intentions to camp there, and he clued me in that I was a little too close for his comfort. I didn't mind moving on and looking for a new spot, which I found about a mile back down the road. I heated some dinner on the camp stove and settled in to read for the rest of the evening before turning in after 10:00.

I was up before the sun, and I was delighted when the first rays hit the distant Henry Mountains and eventually slowly crept down the buttes directly west of me. It was exquisite. Watching the sunrise is one of my favorite things about camping. I had a super quick breakfast of coffee and a donut, replenished the consumables in my backpack, and drove down the road with a friendly wave at the Land Cruiser guy who was up and had a campfire going. The day's hike was around the rim of another canyon, but it had a longer approach than my previous hike. Along the way I saw many chert flakes and even one partially-worked piece. Once again I found something interesting only a short time after beginning to explore the canyon. I was surprised to find a fairly large natural bridge and, off to one side, an alcove that contained the usual fragments of metates, pottery, and chert. I continued hiking but didn't find anything nearly as interesting as the rock art I'd seen previously. There was one very faint petroglyph and an alcove with some chert flakes, but nothing that really did it for me. I reached a good turnaround point and again took a direct approach back to my vehicle. It was a long, 1.5-mile trudge though soft soil, while stepping over or around a lot of low brush. The day was clearer and cooler than the day before, and a light breeze kept me comfortable despite the exertion of walking in the sand. I kept my eyes on the ground to keep my mind off the distance between myself and the Jeep, and I watched many thousands of chert flakes scroll past. There must have been an army of people making arrowheads out there in the flats.

I arrived at the Jeep after having hiked about six miles for the day. During the drive back to the pavement I stopped many times to look through binoculars at features near the rims of other canyons. There's a great deal remaining out there to explore and I'm already considering where to go for my next trip.

So awesome. I've perused this area from space more than a few times. I'd love to spend more time there.

I'd marked a spot in the GPS that I noticed in Google Earth that seemed a likely spot for rock art, but I was still surprised when I actually could see some red pictographs there!

I would love to know your criteria for such a thing based on nothing but satellite imagery! I probably won't ever put it to use so if you want to tell me privately, that'd be cool too. :)

South-facing, curved amphitheater-like alcove, usually with a talus slope at the bottom. I'll send you a screenshot. ;)
Awesome trip! Next time you're in that general area, take a walk across The Block.
Way cool!

I love those buttes. I love the dog art the most.
Great report...great spot...the road looks to be in better shape than this fall??? true?

Yes, it has been graded sometime since mid-October and is in pretty good shape. I drove as far in as Cove Canyon and it was graded at least that far, but I'm not sure how much farther they continued grading.
