Corn Du Cairn (SO00752133)  
Getting to  the top of Corn Du in the Brecon Beacons has been on the to do list for a while .Finally got round to it this week . Took the train to Merthyr  and T4 bus from there to Storey Arms , 
arriving 9.45 .It's a lovely December morning the sun is threatening to make an appearance .  A few people were mulling around  the car park . I walk up to a wooden gate go across the footbridge over the river  . On the other side  Corn Du comes into view the summit is covered in snow . The uphill hike isn't that difficult , adrenaline  ? . I get to the the turning off point on my map Bwlch Duwynt (windy pass)  a lot quicker than I anticipated .  Pausing  for a drink and taking in the spectacular view of the Neuadd Valley ahead  over  snow covered peaks , below me  down in the lush green fields  fog hangs listless over the top's of  trees .
The summit of Corn Du is 500 metres away East to my left  . 
I walk up the a well trodden path that disappears under thick ice . The summit is 50 metres away there's a bit of climbing up and over large slabs of old red sandstone that have been here since the Devonian period 419.2 million years ago . Slippery  than an ice rink . Camera in one hand holding on with  the other  ..
  The Bronze Age Cairn is set on the eastern edge in a spectacular setting .The cairn has a 12 metre diameter . An excavation in 1978 revealed the remains of complex  cyst . Excavated again in 1991 a bronze brooch and spearhead were found inside the chamber  . 
Cairns were used by the living to carry out rituals .Mountains were revered by the ancients  99% of the  cairns I have visited  in the Rhondda uplands are in full view of Corn Du  / Pen Y Fan . 
What a day ..
