A film company is looking for anyone who has seen Morag – the Loch Morar Monster – to take part in a documentary about Nessie’s less famous sister.
At more than 1,000ft, Loch Morar in Lochaber is Britain’s deepest body of freshwater.
And its waters are crystal clear due to the steep-sided walls of the surrounding hills, which means the rainfall does not become peat stained.
After the Loch Ness Monster, Morag is among the best known of Scotland’s legendary monsters, with sightings dating back to 1887.
These include 34 incidents by 1981 – 16 of which were reported by more than one person.
“A peculiar serpent-like creature about 20ft long” was reported by nine people in a boat in 1948, in the same place as the 1887 sighting.
And CMJ Productions, a Canadian production company based in Montreal, is now keen to speak to anyone with a tale to tell about Morag for a documentary it is making as part of a series called Boogeymen.
Researcher Elizabeth Grenier explained that they chose Morag because she was less well-known than Nessie.
She said: “We are going to places where the local monster did not necessarily turn into a tourist attraction.
“The monster serves as a way to discover the highlights, the history and the culture of a community.”
The film crew is due to visit the remote location in Lochaber from Thursday September 25 to Saturday September 27, but it is still looking for more people to take part in the programme.
Ms Grenier said: “I am looking for a local journalist or media analyst, who could comment on the way Morag has been covered by the local, national and international media.
“Eyewitnesses, believers, sceptics, historians or people who helped Elizabeth Montgomery-Campbell during her Loch Morar Survey in the 1970s and anyone who can add something to the story should also get in touch with me.”
The best known encounter with Morag was reported in 1969 when Duncan McDonnel and William Simpson claimed that their speedboat accidentally struck the creature, prompting her to hit back.
McDonnel is said to have retaliated with an oar while Simpson opened fire with his rifle. The monster then sank slowly out of sight.
They described her as being brown and 25-30 feet long, with rough skin and three humps on her back.
