Well Pit Air Temperature - 2014-10 to 2015-04

Well Pit Air Temperature – 2014-10 to 2015-04

Yes, the air temperature really did hover around freezing for two weeks in mid-February. If it didn’t require hoisting a four-inch concrete slab with a rusted lift ring, I’d affix a logger to the copper water pipe running across the pit for some direct samples of the actual water temperature.

It hasn’t ever frozen in the last half-century or so; I’m not going to start worrying now…
