"I drove up a small rise and saw movement out of the corner of my eye. At first glance, I thought it was a spitting cobra that had its hood up, but after a closer inspection, I then saw it was actually two mambas," Treherne wrote. "I quickly flagged the other 2 players in my four ball to slow down."
Treherne said she alerted golfers in other parties to come watch the snake fight, and even called her husband to bring their son to watch nature in action.
"It was amazing to watch and seemed to go on for ages," she wrote. "We debated about carrying on playing the hole, but after a little while longer, we decided to drive past them at a wide berth and go to the next hole."
Treherne said the snakes eventually grew tired and went their separate ways with no clear victor.
"We found concentrating on golf quite difficult over the next few holes. I feel this was a once in a lifetime sighting. And so always make sure you have a camera on this golf course, there is always something exciting that can happen. I just wish I would have I had a better camera with me," she said.
