A walker heard the noise first, a strange chittering coming from a thin cleft in the rock.
Laying down he squinted into it but could see nothing, the sound was louder here echoing slightly and a foetid stench assaulted his nostrils. Thinking it a little strange the walker mentioned it to the Park ranger who, with a companion investigated further shining torches into it, thrusting their fingers into the narrow fissure to feel a warm current of air.
The Ranger baffled by the strange phenomenon contacted an acquaintance in the National Geological Society, who in turn sent along a curious scientist with a pair of eager students. When he showed his visitors to the fissure they were surprised to see it was now wide enough to push an arm into.
They set up their equipment, took recordings of the temperature and the strange sound then the team sent in their prized camera probe, equipped with thermal vision and microphones, it was start of the art and worth a fortune.
The probe was sent in and the investigative team clustered around the screen joined by most of the park employees, all curious to learn the truth behind the strange sound.
As the camera moved downwards on it’s caterpillar treads the cleft slowly widened until it dangled from it’s umbilical, unable get purchase on the rock. They wound the cable steadily out and at half a kilometre down the sound became deafening and the temperature had approached 50 degrees celsius when what resembled the antenna of an impossibly large insect was spotted. The signal stopped shortly after that, the last thing the camera recorded was what looked like a giant pair of mandibles.
The fissure was a metre wide the next day and the man from the Civil Service, who had been summoned by the concerned scientist, called for military advice.
By the time the army convoy arrived the rift, as it was fast becoming, was over three metres in width and the uncanny sound could be heard at some distance.
A drone was sent into the growing fissure, after it did not return there was a brief flurry of actvity as a khaki painted cylindrical object was lowered carefully in by a khaki painted crane truck, the area was cleared and the ground shook as a massive explosion roared into the sky collapsing the fissure in on itself and closing it completely.
The Government sat back relieved as news of the successful operation reached them, as they clapped themselves collectively on the back the phone rang, their faces fell, a second larger deep rift had opened in it’s place and the crew of an overflying helicopter had reported seeing movement there…
