Not really a canyon.
1-1.5hrs access up the Burke canyon. Following (if you can) the old track which runs on the true left side. It is been unmaintained for a very long time, so don’t be surprised if you can’t find/follow it.
There was an old wooden bridge, half broken crossing Strachan Creek. Only a handful of minor features in an open creek, so not really worth a visit.
First recced’ by Annette Philipps and Alain Rohr.
