'Silent Valley' Reservoir, Mountains of 'Mourne' - Ireland

'Silent Valley' Reservoir - Ireland - When the dam/reservoir was being constructed there was a lot of blasting of the rock and because the noise created from the dynamite explosions was so severe all bird life was frightened away - to this day no birds nest or live in this area of the mountains - it is still a 'silent' valley and its a little unsettling when walking there because of the silence.
