There have been oil wells in this nation for around 130 years...with very few cattle deaths. I would call this a rare anomaly.
"Cattle mutilations are up this month".
I would be curious if any crop-dusting took place the days prior to that in the nearby area.
H2S is a silent killer. As long as you can smell it, you are OK. But in lethal concentrations, it dulls your sense of smell and it’s lights out.
Johnson grass would be my first suspect.
Just a guess but sounds like moldy hay.
Aliens???
The Cimarron N.G. is essentially co-located in the Hugoton natural gas field that’s been in production since early in the 20th Century. It was a major source of helium in WW2. Recent exploration has probably opened new formations for production but H2S was not a usual artifact of production out there for over 80 years. That doesn’t mean the oil companies don’t maintain a high awareness of it and train their personnel to detect it. In the 1960s,my dad had a few wells in south-central KS that produced some H2S and signs were posted but the concentrations were considerably less than when the wells first came on line in the 1940s.
I have never seen seven cattle.
I have seen seven cows, bulls, heifers, steers or calves or combinations thereof.
I have seen seven head of cattle.
Maybe it’s a Kansas or mid western thing.
