Baxian cave
This cave lies roughly at the same height as a Giganto-bearing cave just down the road called Bapeng - but Baxian has an obvious absence of Giganto material. Does the cave represent a time slice that just misses the demise of Giganto? Just goes to show that an absence is just as interesting as a presence when it comes to the Giganto story.
