Castleshaw and its reservoirs

A panoramic stitch of four photos showing the two reservoirs here (Upper and Lower Castleshaw). One of our favourite walks follows the valley from left to right and over the far end dam wall before retracing our path back. It is always somewhat muddy and damp but quite beautiful too.
“Castleshaw Roman fort was a castellum in the Roman province of Britannia. Although there is no evidence to substantiate the claim, it has been suggested that Castleshaw Roman fort is the site of Rigodunum, a Brigantian settlement.”

Best full screen and zoomed.

Not sure how Ipernity has calculated this at 15.8mm as the 4 shots were 38mm each.
