Building a 8'x10'x5' deep pond into basically solid rock 6" under ground

The ponds almost ready for the liner. I wanted to get a few more gallons out of it so I dug out the back more to make it more of a rounded/square pond. It was going great until I hit a rock that took me days (nights) to get out. The problem is I could only dig out the front and then when I got it loose i still could not budge it because it had a V shape that was wedged down in the back of it. Finally figured out a way to get the wire wrapped around the tip of it and tied the comealong to a smaller brange of the tree using tie downs and poped it out then pulled it out. Cemented it all smooth once I cleaned it up.

As you can see I covered the wire this time as I had to put a lot of pressure on it to buge this stone out.

Barley got around that rock

Trying to show the V under it...



And the solid rock under it that I could not budge.



I got the rock out that was under it out after I got the big one out and it was huge. Thank good I gave up on chipping it away and found a way to wrap the wire around.

rewraped the wire and pulled it out. BIG ROCK!




And then after I cemented it smooth:

Then I bult a form for the waterfall rock to sit on. 8 bags of cement later (up until 4 on a work day)

And finally got the liner out of the driveway and into the backyard
