Here is an sighting which I came across on the Unexplained Mysteries Forum which had been there for nine years - I wish I had found it earlier. The original link is here and I pull together the posts of the witness, who appears to be named Catherine Ross.
I've joined this forum to share (and hopefully receive explanatory feedback) on a sighting myself and my then husband had of something in Loch Ness in the late summer of 1987. At the time, we were both baffled and perplexed by what we saw, and acknowledged that it was something neither of us could identify rationally. Of course, we were familiar with the legendary 'monster', but the creature we viewed didn't really conform to what I've ever expected 'Nessie' to look like - it certainly did not look like a plesiosaur with a long, thin neck. Anyway, we were holidaying in Inverness and took a trip to the Loch purely for its beautiful, highland views. We were walking long a road which runs alongside the Loch in the vicinity of Dores, where we stopped at a little layby which overlooked the Loch (there was no beach, just a steep incline to the water). It was, if I recall correctly, about four o'clock in the afternoon (although it might have been earlier) and the weather was fine and dry. We were watching the water and looking across the Loch for about ten minutes when we spotted what I took to be a horse swimming off to the right. My first response was panic/worry that a horse would be out in deep water (I thought about 100ft out, although I'm awful with distances). We observed for a while, trying to work out what we were seeing, which is as follows:
A big horse's or camel's head on a thick neck sticking up out of the water with a rounded hump a little behind. The colouring looked black or very, very dark and, like a horse, there was some fuzzy, mane-like stuff sticking up and running down its back. It was moving forward, from the right of our vision to the left, fairly rapidly. We couldn't distinguish facial features or the like. After a minute or so, the head curved downwards into the water (as though diving) and a black, tube-like body followed it, as though the neck just kept going. A few seconds later a fluke-like appendage emerged and then quickly sank down, in a way that reminded me of a whale's tail going under. There was a far amount of spray and disturbed water. Whatever it was did not look like a dinosaur or plesiosaur, and was rather slimy and unpleasant looking.
As you can imagine, this experience was all very confusing, and we mentioned it to the people we were staying with in Inverness, who seemed interested but didn't take it too seriously. They thought perhaps we'd seen a deer. We never reported the sighting to anyone official (heck, we'd have had no idea how to do so) and it's just been a fairly interesting anecdote we've told family and friends whenever a programme about Loch Ness popped up on TV. We had a camera with us at the time, but, stupidly in retrospect, the moment we noticed the creature and stared (both trying to work out what we were seeing) and the moment it went under the water, all happened so quickly that it didn't cross our minds that it was something possibly connected with the mystery and worth photographing. Has anyone else ever had a similar sighting? Is there a natural explanation for this horsey creature? Any thoughts or opinions are warmly welcomed.
