Where do I find an Ice Stone and where do I find Trapinch?

Where do I find an Ice Stone so I can evolve an Alolan Vulpix? Where do I find Trapinch/Vibrava?

Not sure about the Ice Stone, although I recommend using the itemfinder everywhere. It might help, but I don't know for sure.

 

Trapinch/Vibrava are

in V11 content: you need to complete a quest called something like "I need to get stronger" in Sashila Town by winning a difficult battle, then you're given the Scented Lure. Take the Scented Lure to Sandstream Cavern after unlocking it by talking to everyone in Sashila (don't need to talk to everyone exactly, but I don't know which one of the NPCs opens it up for you). When you get to an odd-looking, clickable tile after going through a bunch of rock-climb things, you'll be able to put the scented lure into the hole and it will make a bunch of Trapinch and Vibrava appear.

Alolan Vulpix is in Kristilline Town. It requires to trade A-Sandshrew for it, and for A-Sandshrew, you must breed A-Sandslash, which is on Valor Mountain Calm.
As for Ice Stone, it's reward for finishing Kimono Girls sidequest in Rose Theatre.
