Janaran Falls

From Memory Alpha, the free Star Trek reference.

Janaran Falls is a waterfall on the planet Betazed. It was one of William Riker's and Deanna Troi's (and Thomas Riker's) favorite views on Betazed.

Thomas Riker once made a carving of it in metal to give as a gift to Deanna Troi using nothing but a phaser. (TNG: "Second Chances")
