My father experienced this about 20 years ago at our cabin in the Cariboo region of British Columbia, about 200 miles west of Williams Lake.
Dad got up to get a drink of water during the night. Up the road, at the top of a gentle slope about 100 yards away, he saw a light bobbing like a weak headlight.
Figuring it was someone on a motorcycle, Dad put on his clothes, grabbed a flashlight and went to investigate.
The moon was bright and he didn't need a flashlight. He got within about 25 yards of the bobbing light, about the size of a tennis ball, then it suddenly went out.
And the whole time, not a bit of noise.
Weird!
Dad was more puzzled than spooked. He checked the road the next morning and found no tracks.
He wondered if the moon reflecting off the water might have been responsible. Other nights, he watched for the light and never saw it again.
Just plain weird.
Throughout the world, there are areas known for having strange lights near the ground or mountain peaks.
A recent theory is that geologic faults, with their tremendous pressure, generate a kind of static electricity that manifests itself as ball lightning.
This may be true. I've searched the internet for stories about the Cariboo region and odd lights but haven't found a thing.
Strange balls of light are noted in the northwest area of Utah where I live. I've talked to people who have seen them in this rugged, mountainous country.
Also, years ago while growing up in Spokane, Washington I heard of strange lights seen around the Yakima or Tri-Cities area. Can't remember which area it was.
Interestingly, all of these strange lights are seen in remote mountainous regions.
Perhaps there's something to the theory.
