Cristalino Jungle Lodge borders one of the most intact stretches of southern Amazon rainforest left standing, and the tower named for ornithologist Ted Parker is built to match that scale: 51 metres of cable-guyed steel mast standing clear of a continuous, closed canopy with no gaps or clearings to make the job easier.
A self-supporting lattice at this height would need a footprint and a steel section that stop making sense once the mast passes roughly thirty metres — past that point, a radial spread of guy cables anchored across the forest floor is what keeps the structure stable without turning the base into its own construction project. The stay cables carry the lateral load; the mast itself stays comparatively slender the whole way up.
Its twin, Chip Heaven, stands nearby at the same lodge and the same height — see the next page.
