Been on a wonderful outing today, took in the three henges at Thornborough and also the one a Hutton Moor and the vanished one at Nunwick.

The south henge at Thornborough I have found several references to it having been destroyed by ploughing, but I could see very little evidence of this, it is certainly well worth a visit. Though the Norhern most henge is the most impressive, even under its canopy of trees.

Hutton Moor henge is another well worth a visit. It looks nothing till you get close up, but one there there is an amazing atmosphere of calmness about the place.
