          44 42' 51.50" N      93 5' 23.66" W            293.57 m

4.0  Instrumentation

     Campbell UDG01 ultrasonic depth gage.  The bottom of the sensor was
     2180 mm (average of days 285 to 325 of 1996 when no snow was on the
     ground) above the ground.  To derive snow cover depth, take the 
     difference between the distance from the sensor to the ground surface
     (2180 mm) and the reported distance from the sensor to the snow surface.
