NASA close up picture of Mars ? No, this is a picture of the soil at the pool after sod removal.

We are in the process of old sod removal, multiple aerations and placement of new sod at the pool area.
This picture is an example of how far I could push a screwdriver  into the soil (that is as far as I could go). During the pool and halfway house construction, many pieces of heavy equipment drove back and forth across the pool grounds. This resulted in severely compacted soil not capable of healthy turf growth.
We have aerated the area multiple times and hand raked to remove large stones. Sod is on the schedule and will be installed shortly, pictures to follow.
