比尤特供水的来源
一段时间以来，美国政府专家一直在调查蒙大拿州比特市范围南部平坦的自动供水，并不认为该部分会从自动井中大量发展水，而是将其视为他认为，可以通过将井中浸入不同的裂缝中，以确保大量水以灌溉目的来获得足够的水。他说，这座城市位于一个盆地的北端附近，该盆地的范围超过100平方英里，几乎完全由花岗岩岩石组成。该盆地的内部被填满了深度，并用山缘风化的沉积物被溪流和新鲜的物质冲洗。这种充满碎屑的内部的相对级别的表面被局部称为平坦。巨大的花岗岩岩石没有任何结构，可以使自动井可以获得任何承诺。它的裂缝部分中含有少量的水，但不足以经济开发，除了家庭用途。该公寓的下面的洗涤比基岩更多孔，并且用岩壁限制的水几乎将其存放在表面上。地下水库不时地被雨水落在公寓里和洪水泛滥到山峡谷的公寓上的洪水。它通过沿主要溪流的渗漏和蒸发而不断流失水，并通过银男孩峡谷的底流量在较小的程度上失去水。 The total amount of underground water is considerable, and the annual increment is without question a substantial quantity. The supply is practically all derived from the rain and snow that falls within the basin, and this basin is relatively small, but the porous subsoil of the flat affords good intake conditions and allows much of the precipitation to find its way underground. The supply could, of course, be exhausted by heavy pumping, but with conservative development there is no serious danger of exhaustion. The material underlying the flat consists of irregular alternating beds of poorly assorted, clayey, sandy and gravely sediments". The gravely beds are the best water producers, but even these include much intermixed clay and silt which prevent the water from entering the wells freely.
