|When the Stronach Ridge was clear of the present forestry the rock art site provided a fine view of some of the hills from Beinn Nuis to Goatfell , what had gone unnoticed was that the from the panels the sun would set over the summit of Beinn Nuis at the Summer solstice ,not in itself that noteworthy but there would also have been an eleven minute “Sun roll “ down to the bealach between Beinn Nuis and Beinn Tarsuinn . Unlike other sites where sun rolls can be seen from rock art panels the Stronach Ridge markings have quite a few radials which , if in the correct orientation , could provide an argument for evidence of intentionality and a possible recognition of the phenomena by the engravers , sadly the radials were grouped around 250 -280 with one at 290 degrees when 304 was what was required . This is in itself typical of radials in that they usually follow the slope the rock .
