This cache is placed near Canberra's hidden "pink lake". This naturally occurring pink body of water lies hidden among trees in Bruce, across the road from the University of Canberra. The bright colour makes for an unusual sight in the bush capital, and is a favourite of local photographers. The pinkish hue comes from azolla pinnata, an aquatic microfern that is native to Australia.
The body of water is one of two stormwater runoff ponds off Eardley Street in Bruce. They collect water from Calvary Hospital and the nearby Canberra Institute of Technology campus. The pond’s colour comes and goes, but it is predominantly pink for most of the year. The more sunlight the lake gets, the more pink it looks.
The cache should be relatively easy to find, but you will very quickly realise it may take a bit longer than expected to access the log :)
