Last Friday, I was surprised to see that there was a heavy machinery moving on a landslide-like steep slope. The photograph was taken from a distance, so it's hard to see that there's a heavy machinery, though.
The heavy machinery was a power shovel. It was probably hung with a wire from the top of the slope. The slope might be as steep as 45 degrees, so even just sitting in the driver's seat must be scared.
I don't know if it's a kind of their usual work, but I was impressed by the skills and courage of those construction workers.
