The Lake Cave Doline.
Photographed at Lake Cave, in the Margaret River region of Western Australia at 3.00pm local time on Saturday 21st March for Global Synchronous Shoot #2.
Lake Cave is a small but spectacular cave in the Margaret River region, in the extreme SW corner of Western Australia. This region is best known internationally for its wineries, but is also famous for the quality of its surfing beaches, tall timber forests and caves. A doline is the remains of a cave chamber after it has collapsed. Large karri trees in this doline at the entrance to Lake Cave indicate that this part of the cave collapsed some 500 years ago. The local rock is a limestone sand, [the crossbedding can be seen in the walls of the doline], rather than the more usual coral reef. It is theorised that this is the reason for the prolific number of "straws" found in these caves. A nearby cave has a straw over 6 metres long!
This pano was shot about 2/3rds of the way down the 330 steps into the cave, which is 76 metres deep. The limestone walls are blackened by dirt, fire, and tannin from the trees. Above, you can see the first viewing platform inside the doline. As you pan around and below, you can see where the rest of the steps descend towards the cave entrance proper. Thousands of box spiders live on the walls in dense white webs, seen as small white patches in the blackened areas. Now and again a snake or kangaroo falls into the doline, but this usually doesn't present too much of a problem for the tourists.
We chose to shoot the wrinkle node in the doline rather than in the cave, for its dramatic sense of transition between the upper world and the lower. We were lucky that the overnight storms had passed by the time we reached Lake Cave, the afternoon was cool, calm and overcast, casting an even light without strong shadows. We shot a number of panoramas from both the doline and inside this beautiful cave, and these will be available on our Mastery Multimedia website.
Many thanks to CaveWorks for their permission to shoot within the area, and for the assistance and support of the cave guides during the shoot.
