The walk in to Wollangambe Crater in the Blue Mountains is one of those classic bushwalks that I've been doing every few years since I moved to Sydney.
The walk usually starts at Bell. You walk for a few hours in sometimes quite wild country, to an unusual saucer-shaped feature, the origin of which seems to be the subject of some debate by geologists and others who claim to be in the know.
Was it an asteroid impact, a volcano, or is it just a coincidental arrangement of ridges and valleys formed by the usual erosion forces? Or was it the 'electric machining' referred to on the website thunderbolts.info The aerial photo above is from that site, and is credited to Garry Maxfield. I must admit it's never looked all that cratery to me from within it though.
I did the walk again last weekend, with a party of mostly Wollangambe newbies. The big bushfire a few years back, and the subsequent regrowth, has made the usual 'tricky navigation' sequences even trickier than usual, so we weren't let down in the occasional positional uncertainty department. But it's hard to get very lost these days, with all those GPS devices around.
We all posed for pictures on my favourite armchair tree. And we admired a good crop of late-flowering waratahs.
