Les Henry: Some facts on precipitation cycles

What goes around comes around

This piece deals with long-term water table records as a basis for tracing long-ago annual precipitation. I am dedicating this to the memory of Bill Meneley (1933-2000), who was responsible for establishing the observation wells, which are the basis of what I have to say. He started that work while with the Saskatchewan Research Council. […] Read more

This photo was taken September 24, 2021. This canola field near me had way more nice yellow flowers in late September than it did in mid-July. It looked like a decent crop at that time. With no rain in September and very little frost, it dried up for a second time.
