There was a break in one of the main powerlines for our neighborhood and it was in our backyard. To repair the break, they had to dig a hole in our backyard to get to the cable. By the time they were done, the hole was 7 feet deep. (2 meters).
Interestingly enough, the guys doing the digging thought they would
be done in 3-4 hours. They didn't listen to me when I laughed at
their estimate, and told them it would take two days. Two days later
they finished the hole.
At the end of Day one.
Another shot of the pile.
I wouldn't want this guy's job!
This is why it took two days. All of our yard is Alluvial Plain. In other words, lots of rocks.
