The Mynydd Melyn moraine?

 

 

Out doing a bit of exploring today -- and I think I may have found the traces of a morainic ridge at around 900 ft on the southern flank of the Mynydd Melyn summit.  It's not very obvious on the ground, but there is a distinct linear accumulation of erratic boulders in a field adjacent to the road.  There is a "gravel pit" marked on the map, but it cannot have been uised for gravel -- for stone building materials, mopre likely......

I will go back and explore the feature in more detail when the weather is more auspicious.


Now that Mynydd Dinas is our local mountain, rather than Carningli, I have a lot of exploring to do.  I am more and more convinced, from the appearance of the ground surface and the wide rolling plateau surface, that this was a perfect location for the establishment of a small ice cap at various stages during the Quaternary.

Just to the south of the map reproduced above are the famous Russia Stones, which I have featured in earlier posts.
