Years ago I was a project manager for a developer and one of our sites had an ancient rotational landslide on it.
To determine if it was stable enough to build houses on it a series if holes were bored into the slide area. The holes were about 4’ in diameter and were drilled to a depth where the soil characteristics changed. The soils engineer inspected the soil coming out of the hole to determine at what depth that occurred.
In that case, it was 103’ down.
Then the fun part. A geologist gets in a cage and is slowly lowered into the hole, picking at the side of the hole as he went down to determine if there were multiple fractures of the soil or if the entire mass slid as one. This determined the stability of the slide.
The geologist was first strapped to the top of the cage so if he collapsed that his body would not come out of the cage and he could be safely brought to the surface. He then was put on an oxygen mask as decaying vegetation could produce gasses. Finally he was given a radio as once he descended more than 30’ or so the hole muffled the sound and neither party could hear the other.
I’m thinking you would have cajones of titanium to go 103’ down a tiny hole.
