The summit was deleted from the original list of Marilyns in 1999 but was re-instated due to a change in the recorded summit position. A team including John Barnard surveyed the hill on 18 September 2009 and on 11 February 2010 announced that the summit and col height measurements were 486.9m and 339.2m respectively, and thus it was once again removed from the list of Marilyns.
