Another Run of Sap

The sap ran a bit on Sunday and but not enough to fill our evaporator. It continued today and is still running tonight as the temperature is above freezing and the atmospheric pressure is dropping. The sap will run tonight until the tree freezes or as long as the pressure inside the tree exceeds the atmospheric pressure.The sap and gases inside the tree expand and contract with changes in temperature. This causes a pumping action which makes the sap flow even though the tree is dormant. There is a wall display at our camp that explains the sap process in more detail.

Next weekend looks promising with warmer weather. The Kettle Boys will be here and all our activities will be in full swing.
