Loch Ness

About

Loch Ness is the second largest Scottish loch by surface area at 56.4 km2 (21.8 sq mi) after Loch Lomond, but due to its great depth it is the largest by volume. Its deepest point is 230 m (754 ft), deeper than the height of London's BT Tower at 189 m (620 ft) and deeper than any other loch with the exception of Loch Morar. It contains more fresh water than all lakes in England and Wales combined, and is the largest body of water on the Great Glen Fault, which runs from Inverness in the north to Fort William in the south.

Loch Ness is connected at the southern end by the River Oich and a section of the Caledonian Canal to Loch Oich. At the northern end there is the Bona Narrows which opens out into Loch Dochfour, which feeds the River Ness and a further section of canal to Inverness. The water visibility in Loch Ness is exceptionally low due to high peat content in the surrounding soil.

Nessie

Loch Ness is best known for the alleged sightings of the legendary Loch Ness Monster, also known as "Nessie". So keep an eye out for her!

One of the most iconic images of Nessie is known as the 'Surgeon's Photograph', which many formerly considered to be good evidence of the monster. Its importance lies in the fact that it was the only photographic evidence of a “head and neck” – all the others are humps or disturbances. The image was revealed as a hoax in 1994.

Modern interest in the monster was sparked by the 22 July 1933 sighting, when George Spicer and his wife saw 'a most extraordinary form of animal' cross the road in front of their car. They described the creature as having a large body (about 4 feet (1 metres) high and 25 feet (8 metres) long), and a long, narrow neck, slightly thicker than an elephant's trunk and as long as the ten to twelve feet (3.0 - 3.7 metres) width of the road; the neck had a number of undulations in it. They saw no limbs, possibly because of a dip in the road obscuring the animal's lower portion. It lurched across the road towards the loch 20 yards (20 metres) away, leaving only a trail of broken undergrowth in its wake.

In 1987, Operation Deepscan took place - the biggest sonar exploration of Loch Ness. Twenty-four boats equipped with sonar were deployed across the whole width of the lake and they simultaneously sent out acoustic waves. BBC News reported that the scientists had made sonar contact with a large unidentified object of unusual size and strength. The researchers decided to return to the same spot and re-scan the area. After analysing the SONAR images, it seemed to point to debris at the bottom of the lake, although three of the pictures were of moving debris. Shine speculates that they could be seals that got into the lake, since they would be of about the same magnitude as the objects detected.
