tongaporutu river at low tide

Hubby took this shot of one of the 'sisters'.

I have no idea what these protrusions are. They seemed to have a 'shell' of some sort but that's all I can tell you.  These concretions are found lots of places in NZ.

This shot from inside one of the caves made Hubby's shot look quite tropical.

There are lots of caves along the river in lots of different sizes.

I just love the patterns made in the black sand by water ripples.

These rock layers just amaze me.
