It's a scary feeling when two of your wheels drop off the trail and you're looking off a cliff. I had this same thing happen to me on my way up to the upper Mt. Sherman lot. The trail is nothing but loose scree, and the driver's side tires began to slip off the trail. It's nothing but loose scree for hundreds of feet all the way to the bottom. "No biggie, you've had tires go off trail before, just go slow and turn back into the trail." WRONG. The truck violently slams down the side of the hill and nearly bottomed out, and is now a foot away from disaster. I could've made diamonds from coal at that moment. The truck was so angled I wasn't comfortable getting out on the low side, so I parked it and crawled out the passenger window. At this point, my cousin and I are standing on the trail, catching our breath at 11,000 ft. thinking, "how the HELL do we get out of this?" My first response was to lower the tire pressure as low as I dare – 15 PSI. The scariest part was lowering the PSI on the driver's side and hearing the scree move and slip beneath the tires. I wasn't sure if the scree would give and I'd be tumbling down the hill with the LX. Thankfully, the truck stayed put and the tires were now at 15 PSI. I slowly crept back to the driver's seat from the passenger window, and told my cousin to step on the sliders and lean as far off the passenger side as he could. So, here we are with tires lowered and my cousin leaning like crazy to keep more weight on the passenger wheels. I put the truck in LO and engage the CDL, then painfully put it drive. I slowly begin to creep forward while simultaneously turning the wheels toward the trail. We move forward, but not up. Forward progress is met with scree giving way to the driver side tires. We must have hit a hard spot, or the CDL eventually locked, because around 5 ft later we finally pop back up. I parked the truck on the trail and got out to breath a sigh of relief. We were both pale, sweating, panting, and shaking after the ordeal. That's the scariest situation I've been on the trail. After an unexpected life-threading situation, we proceeded to the upper lot and hiked a 14er. What a day.
I learned three things that day: Preemptive airing down is a good idea, never trust a loose scree trail, and summit beer can also be pre-hike-calm-your-nerves beer.
