Yea it looks like a beacon in the sky but it's a house. You'll never lose it.

Do you ever build into or near mountains?

All the time, wish I had pictures of it... I once had a base inside a rather large flying island in the mountains.  I used eletra to get up to the only access point and it wasn't found for a very long time... That island was hollow by that point..
