Photo by @TimLaman. A high valley in the Lorentz National Park filled with tree ferns and limestone outcrops has a real “lost world” feel to it. I was keeping my eye out for dinosaurs, but no luck. This habitat is at about 3500 meters elevation where temperatures regularly drop to around freezing at night, even here near the equator. See @TimLaman for more from my explorations of the rarely visited alpine environment of Papua, Indonesia. #LostWorld, #Indonesia, #LorentzNationalPark, #Papua, #IndonesiaBiodiversity.
