I took a coat hanger, straightened it out, and then bent it at one point to have a blunt end that could go down in the hole and pull out dirt, along with a garden hose at high pressure. I moved the coat hanger up, down, turned it around getting the dirt out, then, I turned the water on, and I continued to move the hanger while spraying water in there. I got the dirt out well.
