D and I went for a walk along Stony Creek (North Lorne). The walk up the creek valley is not a long one, and is usually regarded as ending at what is known as the "Lilypond".
As it happened, we could climb a little further as the creek was not flowing at all and we were able to walk along the rocky cascade for a hundred metres or so until the way was blocked by the bush.
Another walker drew our attention to an echidna digging away in the bush. It was there all right, but not easily seen and we would never have noticed it. We asked how she had known it was there. She told us that the give away is the noise it makes!
