"Imagine...Water cascading off cliffs the height of Mount Everest and thundering through continuous rainbows, straight into an ocean the color of sapphire wine."
Gideon Seyetik, 2370 ("Second Sight")

Da Vinci Falls were a spectacular set of waterfalls, located on the planet Blue Horizon.

Named after Leonardo da Vinci, they were terraformed by Gideon Seyetik, and considered his "crowning glory." (DS9: "Second Sight")
