At the base of Marble Mountain, there is an entrance to Dong Am Phu Cave. Inside, there is a flight of narrow stairs, which leads up to an opening looking over the village and workshops (plus parking lot) below. It's a precarious ascent up steps which don't have a protective rail on the exposed side. Outside, is a viewing platform. Clinging to this external sculpted wall was a dragonfly. I got several views, each time holding my breath, waiting for it to fly away. It didn't. I breathed again.
