My wrong, Carlesmoor is a lower level sighting tower to the west of Kirkby Malzeard. I was thinking of the un-named trig near sandy hill on Kirkby Malzeard moor/Masham moor (Colsterdale) from where there are other towers within a couple of km and the southern one of which is Carle tower but these are all bigger than in your pic: http://en.wikipedia.org/wiki/Colsterdale_towers
