On Top of the Great Divide

New Year’s eve 2010 was spent up the mountains in Nundle and Tuggolo State Forests about 250km north of Sydney. These are forests along the top of the Great Divide around the 1200 to 1300mtrs high which is pretty high for Australian Mountains. A few months ago in spring when we were last here it was snowing but now its summer and its cool but sunny and dry. The forests are a mixture of native eucalypts and plantation pines. The pine areas are easily accessible but much of the native forest in only accessed by long distance hikes.

Whilst there I met up with Peter Serov. Peter is into all things aquatic with a particular passion for Groundwater Dependent Ecosystems (GDEs). This was all new to me so I teamed up with Peter and I helped him with his groundwater surveying in the area and he helped me with my creek surveys.
