The oldest volcanic rocks consist chiefly of lava flows that in surface exposures
often resemble masses of irregularly piled pillows. The pillow lavas, along with
glassy brecciated rocks were produced by sudden quenching and fracturing of ...

The change in the potentiometric surface caused by pumping depends on the
rate and duration of the pumping and the hydrogeologic setting. Regional long-
term declines in water levels greater than 20 feet are shown on the illustration ...
