Bump in my backyard

So I made this "bump" in my backyard today.

I got shit load of dart that I don't need, so I pilled them on a section of my backyarad.

Here is the "before" picture:


Then the "after picture"



Then I went and got bunch of sod.



Then I covered this bump with the sod.




I need to to name this bump... not sure what I am going to call it, Probably something very boring like "Grass Mountain".

Any good ideas?

Let me know.
