At the junction of the creek and the river, we came on a dyke of basalt, the flat summit of which was so rough that we were compelled to travel along the flats of the creek, which for a long distance ran parallel to the Burdekin.

The soil on the basalt was so shallow that it sustained only a scanty vegetation of grass and some few scattered narrow-leaved Ironbark trees.

We crossed this dyke, however, and at about three miles descended from it into a fine narrow-leaved Ironbark flat, extending along the river, in which another large creek from the south-west joined the Burdekin.

The flat was bounded by hills of limestone, cropping out in large blocks, with visible stratification, but without fossils.

Having passed the third creek in the course of this day's journey, we encamped on the commencement of another basaltic dyke.
