After I hiked up onto a ridge to photograph these jagged peaks in Tombstone Territorial Park, I saw a strong rainstorm approaching in the distance. I thought there could be a rainbow, but didn't think I'd be lucky enough to actually get one. Once the rain stopped and these brilliant colours unfolded in front of me, I ran out from under the huge boulders I was sheltering under and managed to take a few shots before the rainbow faded away very quickly.
