Bache Hill in the Radnor Forest has long been subject to doubt as to its status as a mountain. On OS maps its 610m high point is very close to the agreed height threshold of 2000ft (609.6m), but the trig point stands on an ancient burial mound. Did this man-made structure give Bache Hill an undeserved boost over the line? Hill surveyors Aled Williams and Myrddyn Phillips thought it was high time to settle the question.
