Prims went to the netherworld

I am new to building. I own a piece of first land and was building on it. My perspective was off and I pushd a few things into the ground. Now I can't find them to delete them. Any ideas of how I can find them again?

Here’s two methods to dig em out.

1 While in Edit mode, camera above where they’re buried, click and hold down the left mouse button, and drag open a selection box over the area. Anything buried below will be selected. You can then move em up, delete or whatever.

2 Use the Debug menu to turn off the ground. (Ctrl+ Alt + D to turn the Debug option on in the toolbar if its not.) Click Debug/ Rendering/ Types/ Surface Patch and the ground will disappear with a poof! Then ye can go looking for buried treasure arrrrrrr Do the same again to turn the ground back on.

Happy Spelunking!

Thanks for the advice!
