Spent sometime in the Boartal (Boar Hole - Portal) System to shoot some more for a short documentary being made about my cave photography. I may post a link here when they finish in a couple of weeks. Anyways:

The entrance to Boar Hole leads to this impressive junction area when Boaring Boulevard begins, it is over 40ft high in places and was a challenge to find a place to photograph it from. This doesnt do it justice. Nick Jarvis (the videographer) is shown here backlit with two Number 5 flashbulbs.

In the end of the junction area, a waterfall drops from one of the numerous 100+ft tall domes in the ceiling. It was a very wet weekend! Nick is backlit with a headlamp in a 6 second exposure.

Boaring Boulevard itself is a long and wide passage that is almost perfectly straight for over 900ft. This is one of the few twists and turns in the passage, which held these dimensions the whole way. Back lit with two No. 5 bulbs and the floor was lit by firing an M2 straight at the ground.

Near the end are some of the most spectacular displays of an uncommon feature called anastmoses. These features form in the ceiling by differential erosion and are uncommon. Displays of this size are rare. Some are over 40ft in depth (height?). Backlit with a No 5.

the end of Boaring Boulevard (external link) on Flickr

Boaring Boulevard ends in a large junction with high mud slopes. In one of the few times I needed a longer lens, I used a 50mm prme lens to show the size of the junction area. Nick ran the camera for this, and thus we used a No 5 to backlight Emily and I used an M2 to fill the middle area leaving me as a black outline.

The passage behind Emily continues to the Portal side of the system, the system totals nearly 10mi. Backlit with a No 5 bulb.


C&C welcome, enjoy!
