It was good to be able to use the NPWS pass to drive in there and we spotted this one without consulting the GPSr. Recognise the top as a structure we've seen on many pedestal trigs where the vanes have been 'replaced'. An impressive stone structure, all trigs should be like this one! A very large family of ducks grazed nearby - I think the parents have adopted a few of their 17 ducklings.
