Topic: Caves - Twin Creeks
Twin Creeks is south of Beach Two. An impassable bluff on Twin Creeks’ southern boundary leads around to White Cliffs.
TWIN CREEKS CAVE
On the seaward side of the cliff immediately south of the southern creek there is a blind corridor cave. (Blind as of 2004). Above the south-western entrance, there is a huge, open, overhanging bowl. The cave roof is very high.
The Te Kawau Pa, Three Sisters, Twin Arches and Cathedral caves all have north-western facing large, open bowls at their main entrances. Conversely, the Passageway cave at The Point and Twin Creeks cave both have south-western facing large, open bowls at their main entrances. Interestingly, the Passageway and Twin Creeks caves have a small horseshoe bay leading around to a north facing cliff promontory that gives protection to some degree from the prevailing south-western sea conditions.
Twin Creeks is a highly active erosion site. This is because two creeks drain into it, one from the north and the other from the south. Added to this is the slumping nature of some of the land forms. Further, due to the beach and cliff topography, wave action here is particularly erosive. Dumping waves are a distinctive feature.

CLIFF SEQUENCING. View of the north-eastern cliff exterior. At this point the cave is not a through-going cave. The seaward, exterior view of the south western cave was documented, but not the developing entrance on the landward, north-eastern side. No internal photos of the cave were taken.
PHO2008-664, 666-667 show both the location of Twin Creek’s large open blind cave and its parent cliff.
The other images show small, blind caves in the process of being carved out.

SUPER STORM EVENT. Super-Storm Three. A massive rain event. The road down to Twin Creeks was completely impassable by car. I had to trudge down. I took a series of 5 images, looking from south to north. They included the cave’s north-eastern cliff exterior and the small, developing landward entrance. Due to dangerous conditions, I couldn’t access the cave’s seaward entrance.

The sea had finally punched through to the landward, north-eastern cliff entrance. As such, THE CAVE IS NOW A THROUGH-GOING CAVE with two entrances. According to the Russell Gibbs, this occurred around April or May 2005 (from memory). The images here show the landward entrance.
Stormy conditions. Though the photo doesn’t show the cave, it does show a large spray plume splashing high up at the cave’s main seaward entrance (the entrance itself is obscured). The topography causes the wind to funnel, thus increasing its velocity relative to the site.

At the main entrance, on the northern side, the developing arch I noted on 8.2.04 (not broken through) is now a through-going arch, or an arch proper. The photo shows the lit up north-eastern exit, or rear entrance. Another viewpoint shows the arch from the northern side and how it is part of a fault-line going from the bottom to the top of the exterior cliff wall. No internal view at this time.
As an aside, PHO2011-1081 shows a forming blind cave just north of the northern arch.
As the sand level was very high, I was able to walk through the cave. Usually there is water in here. It is the first time I have been inside it. I find going into places like this to be very scary because you know that if the roof collapsed, then you’d be deadsville. If not, then you soon would be because you’d drown in the incoming tide.
I was amazed at high the chamber was. It is the highest of any of the other through or closed caves I have been in, including Cathedral Cave on the Four Brothers Beach.
Wave action here can best be described as boiling under high intensity storm conditions. This is due to a high incidence of backwash and cross wave action. The photo shown was taken from the south-western main entrance and shows the small semi-enclosed bay that shields the entrance from direct south-western sea conditions. On this day, though technically speaking the sea was ‘rough’, here it was more like a short chop. In other words, the waves were more dumpers than rushing up the beach.
A big swell with dumping waves was present, although the sea state itself was relatively calm. To the left of the frame, a wide angle view clearly shows the north-eastern entrance, with water highlighting a partial interior view.
I was primarily interested in documenting the ongoing destruction of the Middle Rock, but I did observe a fresh rock pile at the northern side of the cave’s south-western entrance. The recently formed arch that I photographed on 27.10.2007 has now been destroyed. I was quite surprised as I thought it would live longer than it did.
An overcast day. I documented looking through the cave from its north-eastern entrance. That is, I was able to show both entrances, but from the north-eastern side looking towards the south-western, seaward side. As the cave is a narrow, corridor cave for most of its length, I haven’t got any strictly internal shots.
The photo, while not showing the cave as such, because it was taken with my ‘new’ panoramic camera, does show the Twin Creeks beach area where it is located. Specifically, the middle sloping cliff section is where the cave is housed.

The cave appears to be relatively intact, but the outer cave cliff wall is being carved inward by driving rain and energetic wave action. If it continues unabated, it could create a hole in the cave’s roof and collapse it in the middle.
PHO2011-1917 shows the cave’s landward entrance, while PHO2011-1919 shows part of the cave’s larger, seaward entrance.
