The Tengger Massif is endlessly photographable, one of those surreal experiences that you’d more ascribe to a high-budget movie or video game than a real place. It’s a massive crater more than three miles across, the remnants of a volcanic explosion millions of years ago. The west side of the crater is a vast, living prairie: grasses ripple in the gentle wind under drifting sea of clouds. To the north lies the volcano Bromo, carrying the torch of Tengger’s volcanic legacy with a low, continuous roar as it sends thick billows of noxious gas skyward. And to the east lies the sandsea, a desert devoid of life except for a few patches of grass eking out an existence on a barren landscape of sand and dust.
