Well, not sure if it counts as I wasn't in a 4X4 at the time, but I had an incident this spring that almost required search and rescue.
I was in Moab with 3 friends on a mountainbiking trip, we were there for ten days from late April/early May. We hit some amazing trails and had a blast.
On Day 7, we decided to do the Whole Enchilada trail. Well, as much of it as we could anyway, the upper part was still closed due to snow. For those not familiar with Moab or the trail, it's basically 30 miles of downhill trails starting at near the top of the LaSalle mountains that overlook Moab. You can drive to the top, or take a shuttle from town. We left 1 vehicle at the bottom. near town, and the 4 of us drove up the mountain in out other rental, a Dodge Caravan (props to the Caravan, btw, we fit 4 riders, bikes, and gear in the van. We could only get 3 of us and gear in the Suburban).
We started descending from the Jimmy Keene trail, which is about 8,500 feet elevation, about 4500 feet up from Moab. I did the trail from this point last year, it was 24 miles of mostly downhill trails. Probably the most fun and intimidationg ride I've ever done. It starts off as singletrack trough the forest, and as you descend the trees thin and the trail gets rockier. Parts skirt right on the edge of cliffs, or across sheer rock faces. Some of the descents are on incredibly steep rock faces, good brakes are a must, and the pucker factor is high. Toward the bottom, the trail winds down through the canyon and along the Colorado River; one side of the trail is the mountain, the other side is a steep drop off. Low margin for error, high penalty for failure.
It's beautiful, it's exhilarating, but no mistake, a wrong move at an inopportune time could be your last.
Anyway, we were about halfway down. We were making good time, and having a blast. I felt like I was riding well; the trail seemed much less intimidating than it had the first time I rode it. We had made it through the woods, and we had descended some of the steep rock faces. I had stopped to get my obligatory photo at the edge of the cliff, shown here.
About 20 minutes later, on a not so difficult part of the trail, the day took a bad turn. Maybe I was complacent after tacking the tougher bits earlier, perhaps I was just enjoying the view. I was coming around a bend at a wider point of the trail. I wasn't taking any particular line that I could see, I was just taking the most direct line. I rolled a small ledge, maybe 10" or so high, which is nothing. However, I did not see the little slab of stone sticking up on the other side, at exactly the right spacing to grab my 29" front wheel. The bike stopped cold; I did not. As the bike pivoted forward on it's front wheel, I went up and over the handlebars, falling straight down toward a stone slab. I think I was trying to rotate to land on my back, I had broken a wrist going over the bars once and was trying to prevent that.
I did not make the rotation, I landed on my left side. After laying there and catching my breath for a few minutes, I realized I could not get up. My buddies helped me up, and when I tested my left leg, a lightning bolt shot up it. My worst fear realized: Injured miles from any civilization and not being able to walk out.
My friends kept cool heads, we were roughly in the middle of the ride, there was a vehicle 12 miles up, or 12 miles down. Neither was an option.
Earlier in the ride we had heard vehicles up there, we knew thee was a Jeep road nearby. My friends left me to scout the trail to find it. My buddy Nate returned 20 minutes later, back up the trail and off to the side there was an offshoot that led to the road.
Luckily, while he's no bigger than I am, Nate is in great shape. He literally carried me on his back, back UP the trail at least 1/4 mile to the trail to the Jeep road, and then another 1/8th at least to the road. There, my other friend had managed to flag down two girls that were heading up in a JKU that were willing to help. They had room for two, Nate got me in the Jeep and rode with us. They took us back down the mountain via the Jeep road, and straight to the ER.
Diagnosis was broken left hip. Had surgery the next morning, and flew back home 5 days later. I've been recovering all summer, and I finally got back on the (road) bike 3 weeks ago.
I'm glad I have great friends, and if I were to believe in angels and things like that, it would be those 2 girls showing up. They wouldn't even take beer money.
At they hospital they said I was very fortunate to get a ride down, recovering people from up there can sometimes turn into a 5 or 6 hour ordeal. Which would have put me out there well after dark.
Sorry for the long read, I just realized how long that is.
CLIFF NOTES: Broke my hip in the middle of nowhere, 2 girls in a Jeep brought my ass down off the mountain to the ER.
