I just moved into a new house in Bend Oregon, and Iāve been working outside in the garden. Yesterday I had to dig up this huge rock that was in the way back of my flower garden but the rock was also partially under the fence. Behind the fence there is nothingā¦ Itās all just open land with trees and dirt and rocks. I found all of these. The one Iām most curious about is the large one with the Crystal in the center. Can anyone tell me what this is? Any information would be appreciated!
