There are trillions and trillions of rocks at Joshua Tree National Park and I hiked over many of them on my way to the Contact Mine. At least it felt that way. Big rocks, little rocks, sharp rocks, moving rocks. I also discovered a new sport I call “Rock Surfing.” It’s a spontaneous and unexpected event that occurred several times when I stepped or jumped onto large, flat rocks along the trail that I assumed would not move when I landed on them. Depending on the angle of the trail, I sometimes caught a pretty good scree wave and “surfed” the trail several feet.
