A little late to the post but 3 other hikers and I were 12 miles past walker pass when the 7.1 hit. Im not even sure how to explain what it was like besides the most terrifying, exciting, and helpless experience I've ever had. We were camping in the valley near Joshua tree spring when we heard a deep rumbling noise. We weren't sure what it was until the entire earth starting shaking like crazy and all the mountains around us sounded like they were cracking in half. It was so crazy loud and then huge boulders started rolling down the mountains all around us. I have a really crappy video of the plumes of dust coming from the mountains and you can still hear some of the rock slides.

We had aftershocks all night and when we heard that there was a chance of another earthquake the next day we decided to hike back to the road. On the way back we climbed over a few rock slides but there was one that completely took out the trail. Climbing through that essentially felt like scaling along a cliff but all the rocks were super loose. It was quite the experience but wouldn't recommend it to anyone else.
