If rock is encountered during the boring process, additional information should be recorded in the boring log, including the thickness and depth of the rock unit; a description of the rock unit; percent recovery and rock quality designation; description of joints, fractures and bedding planes; location of core fracturing; type and size of core barrel and depths where casing is used; descriptions of penetration rate; zones of drilling fluid loss; zones of water gain; and any unusual occurrences, such as change in color of return wash water. be a narrow gorge or a small valley with enough catchments area available 'fhe nature of the ground has significantly different im- Drainage and run-off.
