Photograph taken by Don MacCaskill and image courtesy of Bridget MacCaskill, Strathyre. Don was based as Head Forester at Inverinan from about 1960 through to about 1968 before transferring initially to Allean Forest and then Strathyre Forest in 1972.
Helicopter has either finished it run or about to start another as the flag of a marker can just be seen bottom right. A pylon line can just be seen in the distance through the gloom. Does this point to Allean Forest circa 1969?
