See how far various soil types spread when dumped
Description of my soil test
We could use this knowledge to create a “wall” of rock or slag before dumping waste in the ocean.
I also noticed that when digging the results are very similar. It’s harder to test this because when digging you can’t guarantee to get a single type of soil. For example, when digging into Coal/Iron/Copper we usually get some dirt/rock/gravel, and there could be a top level of dirt as well. So results may vary.
However, if the soil is mostly Coal/Iron/Copper or even Rock, I may not bother with retaining wall as using them (especially staggered every 5 levels) will result in taking much more space.
