David Elder, an amateur photographer, was attempting to get photos of a swan from a pier at Fort Augustus on the southwest end of Loch Ness when something mysterious caught his eye disturbing the calm waters.
He described it to the UK Mirror as a "solid black object" just under the water that created a wave atop the lake surface. The sighting immediately fueled speculation that this might have been a Loch Ness Monster sighting.
Elder, 50, also took video of the unidentified "sea creature." Watch:
"Out of the corner of my right eye, I caught site of a black area of water about 15 feet long, which developed into a kind of bow wave," Elder of East Kilbride told the Mirror.
"I'm convinced this was caused by a solid black object under the water. The water was very still at the time and there were no ripples coming off the wave and no other activity on the water.
"Water was definitely going over something solid and making the wave. It looks like the sort of wave perhaps created by a windsurfing board, but there was nobody on the Loch at the time, no boats, nothing.
"It is something I just can't explain."
Apparently, nobody can.
The lake in the Highlands of Scotland stretches 23 miles long, is 755 feet deep and was made famous by alleged sightings of a legendary sea monster dubbed Nessie.
The Loch Ness Monster dates to medieval times but became more widespread in the public eye in November 1933 when Hugh Gray photographed a creature with a long tail and four stumpy-looking objects making a commotion in the water. The most famous photo of Nessie was taken a year later. The Mirror explains:
Perhaps the most famous picture of Nessie was taken in 1934 by Robert Kenneth Wilson, a London gynaecologist.
The picture showed what looked like a long neck and head rising from the water.
However, it turned out to be a toy submarine bought from Woolworths in an hoax set up by Marmaduke Wetherell, who had been ridiculed by the national press over his hapless search for the beast.
Skeptics will claim the most recent sighting is merely a wave created by a freak gust of wind or other natural phenomenon, according to the Daily Mail.
Others will contend this is further proof that the Loch Ness Monster exists.
Either way, the legend of Nessie grows.
