Before the drive back to Wellington, Justin, Hamish and I took the deadend road out to Castlepoint, a small seaside community with a spectacular geologic setting. Here a great reef-like band of highly fossiliferous sandstone stretches 2 kilometers along the coast with some impressive features: the Castle, a 160m high promontory with a vertical cliff on its seaward side, a long, low natural causeway bounding a picturesque sheltered cove, and Castlepoint itself with its well-maintained lighthouse, and dramatic clifftop views. With a little careful footing, much of the point is able to be traversed on narrow natural platforms within feet of vertical cliffs plunging into a blue sea. Despite strong winds and the occasional passing squall, the sea was remarkably calm. In places, natural weathering of the sandstone (above) produced uncanny cobbled surfaces certainly enhancing the castle-like feel of the place. I noticed a great diversity of shells in the sandstone. I was later informed the shells lived in a wide variety of environments from shallow to very deep. Because of the relatively good preservation of the deep water fauna, it has been suggested the sandstone was deposited into a deep submarine canyon which transported sediment and shells from the shallow shelf environment. We enjoyed exploring for about an hour before food called us into a local cafe.
The day was rounded off with a grand feast at one of Wellington's finest Indian restaurants. Thanks to Justin for sorting everything out. It was a nice escape before the final push to thesis submission.
