Prominence Peaks


Miller Peak is the highest peak of the Huachuca Mountains, in far-south Arizona, near the city of SIerra Vista and the Fort Huachuca Military Reservation. The Huachuca Mountains are one of the "sky island" ranges of southeastern Arizona. It's easy to picture the deserts as a sea, with the ranges rising dramatically as distinct islands. These ranges tend to be compact but very tall, with prominence figures approaching a vertical mile. In fact, Miller Peak has a shade over 5,000 feet of prominence, making it one of just 57 such peaks in the mainland United States with this status.

There are three main routes to the top of Miller Peak, all involving the Crest Trail in some manner. Given the range's proximity to the Mexican border, it is not uncommon for border crossers to use these trails to enter into the United States. The southernmost trailhead at Montezuma Pass is just one mile north of the border. However, encounters are somewhat rare, and hikers are as safe as they are on any other range in the state. Beth and I had no qualms about being here.

We chose Miller Peak as the primary goal for the July 4th weekend. Our drive to Sierra Vista went without incident, but the Quality Inn we stayed at was horrible. The room's air-conditioning wasn't working, and the temperature inside the room was above 90 degrees. It was extremely uncomfortable, but the place was packed and we could not get a room change. We didn't get to sleep until 3 a.m.

We had planned the actual hike for Sunday (the 3rd), but the lack of sleep and uncomfortable conditions put us in no mood for a hike, so we spent the day driving around the area. We drove the dirt road that leads to the Carr Peak Trailhead and Reef Townsite, which is one of the trailheads to Miller Peak. The area was interesting, but the road itself was far more interesting, being a narrow and exposed dirt road with multiple switchbacks. Later, we drove south to the Coronado National Monument, then to Montezuma Pass (the southern trailhead), and down the other side into the remote San Rafael Valley. We circled around the south and west foothills of the Huachuca Mountains, then passed through the Fort Huachuca Military Reservation directly back to Sierra Vista, going through the checkpoints and car-searches in order to get permission to drive across the base.

Monday the 4th started well, and Beth felt good enough to attempt the hike. We opted for the southern trailhead, and after some preparation, arrived to the small parking area around 7:30 a.m. We were the only ones there. We started hiking at 8 a.m. in warm conditions. We crossed the road and found the trail, and started in. At first, the trail has easy gradients as it bypasses a small foreground hill. After that, the trail gains steeper up the southeast-facing slopes, passing a few mine shafts along the way. There is no tree cover here and it was warm, but we made good time. We surmounted a pass at a ridgepoint near Peak 7964. To here we'd gained 1,300 feet in two miles. We took a break. So far, we'd not seen a single person.

Now on the east-facing slopes, we entered into a small copse of trees. We hoped the shade might offer some relief from the sun, but apparently every insect in the range thought so, too, and we had no respite from the bugs. Ironically, it was a relief to be back into the open, where the brush was about knee high and very woody. The upper ridges of the Huachucas were now visible.

A few minutes passed, and we were approaching a point where the trail meets the crest again, and crosses to the west side. Here, we saw two men appear. Both were wearing flannel, jeans and work boots, and were obviously Mexican crossers or coyotes. Beth was in front of me by a couple feet, and we decided to meet them head on. I greeted them in my meager Spanish, and they greeted us back. We wanted no part of them, and as I suspected, they wanted no part of us. The whole encounter lasted as long as it took for us to pass, perhaps 15 seconds. We kept walking and after a minute or so, we stopped to assess what had just happened. Looking back, they were long gone. We noticed evidence of the crossers, including food wrappers, water bottles and an occasional piece of clothing. There was a good chance that a batch of them were probably hiding in the brush as we passed.

After that, the rest of the hike was rather unexciting. We continued northbound on the Crest Trail, the forest growing slightly thicker as we gained elevation. The day's warmth wasn't too bad, and we made decent time. Finally, the Crest Trail meets the trail coming in from the north (the Carr Peak Trail), and the last mile was up a steep series of switchbacks hewn into the rock to support a fire lookout that once stood atop the peak. We summitted around 11:30 a.m., a five-mile hike with nearly 3,000 feet of gain.

We spent about 20 minutes up top, resting and admiring the views from this lofty perch. The day was clear and we had hundred-mile views in all directions. However, the insects were bombarding us, and it was warm, so we decided to get moving before too long. We hiked down the mile to where the trails met, and we hiked another few minutes south on the Crest Trail, taking a break in a wide area in a glade of trees. Then things got real interesting.

We heard some bashing and voices in the trees, thinking it might be more Mexicans. Suddenly, two men in body armor, fatigues and assault rifles come bursting out, all excited, asking "if we'd seen a whole group of Mexicans pass through here." We told them of the two guys we'd seen earlier, but that was nearly three hours ago, and they were probably in Mexico by now. These two guys were after a group of "20 or 30 Mexicans". Soon, they calmed down and sat with us.

They had been dropped into the range by helicopter a few hours ago, evidently in hot pursuit of a large group of crossers. They asked us what we were doing here. We said we were hiking. They asked us what peak that was, pointing at Miller Peak, so we told them it was Miller Peak. They weren't interrogating us. They were very friendly and probably relieved to see us and be able to take a break from all the running around. We asked them if we should be concerned and they said no, that the crossers will make every effort to remain unseen.

These two guys were young and full of energy, but apparently did not carry a map. We did not see a GPS but then again, maybe they had it hidden. They then asked us which way was out, as in if they follow this trail, will they get out? We said yes, it'll take you down to Montezuma Pass. After 15 minutes, they got up and started walking. We gave them a few minutes head start, then we resumed our hike. Occasionally, we would see the two guys a few hundred yards ahead of us. We had essentially an armed escort off the mountain.

We took our walk out slowly to allow for Beth's knees to rest. We did not see a single other person on our hike out. We were back to the parking area at 4 p.m., the warmth of the day much more noticeable now that were lower in elevation. We exited via Sierra Vista, and drove home that evening. The temperatures in the deserts had been around 110 degrees today, and it felt like the 90s at the trailhead. However, it had been a clear, blue afternoon, with no hints of clouds or storms. Just lots of bugs.

We never felt in harm's way where we were, and despite all the histrionic warnings about hordes of border crossers, actual encounters with them while on a hike, and being robbed or hassled, is extremely low. Nevertheless, it pays to pay attention, and if border crossers isn't your thing, the north trailhead from the Reef Townsite may be preferable.
