Saline seeps appear where glacial till overlays an impermeable layer. During fallow, increased
percolation picks up salts and carries them deeper into the soil. When salty water reaches the tight
layer, it spreads out sideways, flowing downslope underground. The salty water seeps to the surface on
a lower field and the water evaporates leaving salt on the soil surface.
