I am considering the same question and the issues are:
What to do with the material I removed? Seems to be building rubble which I reckon is around 50 tons
What state will the pool sides be in? It is metal (maybe stainless steel as I can't see any rust and it's been underground for 15 years)
What has happened to the bottom? I presume that it has been deliberately punctured as the rubble in there is dry without any smell
Is the effort worth the return in the UK as how often is the weather good enough to use it?
Dirt
A hole has no dirt in it, so zero If the hole was filled with dirt, it would be 27 feet3
A "Terrarium" would be the dirt filled opposite to an Aquarium
There are no age limits as long as you can control your dirt bike.
dirt bike pants. jersy, helemt, boots.gloves,goggles
This is a homogeneous mixture.
None but the hole can be filled in with dirt with the given dimensions.
You would call it a "man..." A waste of space filled with nothing more than dirt
the problems they have are that the dirt that is in the lungs does not brushed out by the cilia, causing the lungs to be filled with black dirt, making it harder to breathe.
No
It is built of bricks, stone and dirt. Slabs of stone were used for the base and sides of the wall and is filled with dirt, rocks and rubble.
