Spring (hydrology)

Definition and stakes

George P. Marsh,  The Earth as Modified by Human Action

“ Water runs over them only in the spring, in the rare cases when they have been pressed down smoothly and compactly by the weight of the snow—a state in which they remain only until they are dry, when shrinkage and the action of the wind soon roughen the surface so as effectually to stop, by absorption, all flow of water. I have observed that when a sudden frost succeeds a thaw at the close of the winter, after the snow has principally disappeared, the water in and between the layers of leaves sometimes freezes into a solid crust, which allows the flow of water over it. ”

Various,  The Irish Penny Journal, Vol. 1 No…

“ A certain quantity of the water which is absorbed by the ground after rain must penetrate to a great depth, must descend, in fact, until at 11⁄2 miles it is boiled and driven up again to find some outlet as a spring. In rising up, however, it is for the most part cooled; but having charged itself with various saline and metallic bodies, under the most favourable circumstances of high temperature and pressure, it issues as a hot mineral spring or spa. ”

Enos A. Mills,  The Rocky Mountain Wonderland

“ Every winter ice thrusts its expansive wedge into each opening. Places are so shattered by this explosive action that thousands of gallons of water are admitted. This collects in openings, and the following winter the freezing and forcing continues. During the winter the irresistible expansion of freezing water thus pushes the rocks and widens the openings with a force that is slow but powerful. Winter by winter rocks are moved; summer by summer the water helps enlarge the opening. Years or centuries go by, and at last during a rainy time or in the spring thaw a mass slips away or falls over. ”
