A detailed survey of the summit and the col was made in 2010, confirming their heights as +/- and +/- respectively, giving a prominence of +/- and confirming the hill's status as a Marilyn. The col is a point on the railway line east of Silverdale, the further north of two pedestrian railway crossings near Waterslack.
