National Geographic Sea Bird arrived at Santa Rosa Island early this morning. One of our hiking destinations was the Torrey Pines grove, a millennia-old relic of the Pleistocene era, when the island was cooler and wetter. Santa Rosa Island is also the discovery site of the remains of a pygmy mammoth and the Arlington Springs Man. Supporting evidence indicates they were found together on the island over 10,000 years ago. As we entered the quiet trail of Cherry Canyon, it was easy to feel like we had stepped into a distant landscape far back in time.
