A micro climate in the bog
The Boardwalk was restored in 2007
as a result of the Ontario Trillium Grant award.

TEMPERATURE MONITORING 2007
Temperature data loggers were placed in Cold Creek
- just downstream of groundwater discharge points (mid Boardwalk),
- at the culvert where Cold Creek leaves the property on the 11th Concession and
- in a surface water pond to the east of the barn that fills in the spring and dries up by mid summer.
The temperature of Cold Creek never rose above 15C in the summer of 2007 and gained only 5 degrees from April to August.
As Cold Creek flowed from the upwelling sources to the 11th Concession the temperature rose only 2 degrees.
In comparison, the pond surface water was always 5 to 15 degrees warmer than Cold Creek.

A MICRO-CLIMATE IS FORMED
The cold ground water discharge that forms Cold Creek together with the shade from the dense conifer tree cover lowers the air temperature about 10 degrees in summer.
In winter Cold Creek never freezes and the air temperature is warmer as a result of the continuously flowing creek. |

Above is one of the ground water upwelling sites. The brown colouration is oxidized iron, the sheen in the lower middle of the photo is natural organic (humic acid) material.

| In the same pool a clay bowl has formed as a result of turbulence from an upwelling ground water spring. Clay bowls like this appear and disappear as the discharge sites relocate around the pool. |
