At Gibson the public water supply is obtained from three wells 55 feet 

 in depth and 7 inches in diameter. Many private wells are obtained at 

 12 to 25 feet, though a few are 45 to 55 feet. They are largely through 

 sand and gravel, the town being situated on a plain just outside the Bloom- 

 ington morainic system, which apparently received a coating of sand and 

 gravel as a morainic outwash. A boring for coal at this city was sunk to a 

 depth of '705 feet and penetrated 1 75 feet of drift.
