This map was an unusually informative one from the ACT Government. Shows distances (totaling 8.5km) and gives a good idea of the topography. Well done Parks and Conservation!
Here are some smaller boulders close to the starting point.
Going up the track there had been a bit of management burning happening. This certainly made the walking easier. On top of the ridge that hadn't happened and the thickness of the regrown Daviesia mimosoides was almost claustrophobic.
As I know some of the readership will be anxious to follow up on the "6 orchid species" here we go. First up we have Stegostyla moschata.
Diuris monticola. This was the last species found, but I have included it here to keep the Diuris together. The image doesn't show the nest of small black ants at the base of the stem: neither the camera nor I spotted them until they invaded my arm, which was resting on the ground!
treyvaudii. The unopened florets produced some strange looking heads in other examples.
Utricularia dichotoma. I wasn't keen enough to wade into the water for a closeup so the second 'zoom and crop' image will have to do!
