I went bouldering with a mate up at the Reservoir (Waverley Park) yesterday evening, perfect conditions for it and a great way to end the day.
Whilst i was there i noticed that there were a lot of gouge marks on the left hand wall. It looks to me (although i could be mistaken) very much like someone has been climbing there in crampons. Now i know that its not exactly Font but it is one of the nicest pieces of featured sandstone around Hobart and unlike the huge tick marks the impacts of crampons on this quite soft rock are permanent and pretty unsightly.
Im not against practicing for mixed climbing or whatever the perpetrator was up to, but maybe a quarry of harder rock might be a much better venue for this sort of thing, there are plenty of those around.
