For my contribution to Nature Week, we're going to have an image guessing contest. Please refrain from using Google/Wikipedia for the first 24 hours after each image is posted. If no one has guessed correctly by then, have at it! Some of these may be unique formations with a proper name, while for others I'll accept a more general answer.

Here is the first image:

A termite mound?

Correct!

 

Next one coming up in a bit.

Ant hills?

I agree with Ry.

Keep guessing!

Gopher mounds?

That was my 2nd guess, Lily!

Well, no one else has guessed at this point, so I'll give gopher mounds a Close Enough!

 

They're mole hills.  :)

This one might be a little tricky:

 

idk grave mound?

I've no idea...

 

Moles?

idk grave mound?

 

I guess it wasn't as tricky as I thought.

Insect lair ?

Can you be more specific?

Ant lair?

Yep! Specifically, leafcutter ants. Next image coming in a bit.

Hubby knew this one. He was looking over my shoulder.

 

I was more mesmerized by the sight of it.

This one is worth up to two points:

 

Terrace?

Rice farming?

Rice terrace is correct, but can anyone name it?  This location is often named in discussions of the Eighth Wonder of the World.

No idea.
