Last week we had some really cold temps with wind.
This combined with a bad electrical connection led to some ice build up on a sheep watering bowl.
The small dark open spot is due to natural convection heat rising from the vertical culvert from a depth of 10 feet.
The second photo shows the repaired water bowl with the thermostatic controlled electric heater working.
I think we will stay inside!
