Geocache Description:


 

Cornucopia is a little seaside village nestled at the western edge of the Bayfield Peninsula along highway 13. Siskiwit Bay and the Siskiwit River form a natural harbor for both recreational and commercial fishing vessels. Just east of the marina complex is the township museum, Halvorson's commercial fishing operation, the town park with picnic tables and swimming beach, and this artesian well.

Where is this water coming from?
Porous stone is sandwiched between a top and bottom layer of an impermeable substance like clay or rock. The artesian water pressure is kept high due to porous stone being crushed between impermeable rocks along with the water’s density, and elevation of recharge zone (gravity). When you get to a point below the entryway of the flow, there is enough pressure (artesian pressure) to bring the water up. The water in the aquifer is also under enough pressure that, when the aquifer is tapped by a well such as this, the water rises up the well bore to a level that is above the top of the aquifer called the potentiometric surface.

The temperature of the water from artesian wells is generally constant because of its depth. Depending on the well depth the water temperature can be a few degrees above the annual mean temperature.

TO LOG THIS CACHE:
1) Determine the output of the well in gallons per minute (gpm) and/or measure the temperature of the water (°F).
