Originally created in Linden World by resident Steller Sunshine, back in 2002 (according to Hamlet Au on his New World Notes, she was the first Alpha user and created this overnight), it made the move to the Grid in 2003. It's located in Welsh, at this location. The Beanstalk is a game. Without using flight, you're supposed to jump from leaf to leaf, trying to reach the top.
The photo is a wide shot of the area, that little dot you see near the Easter Island style head is me, in an extremely rare trip to the mainland, looking at the stalk.
