The Bear Cave

One evening on our caving expedition I heard about a cave where a complete bear skeleton is lying on the floor. This sounded like an excellent photographic opportunity and a chance to see something quite unusual. So we organised the kit we needed to descend the 20 metre deep vertical entrance shaft to the cave, and assembled the camera kit. Once safely down the vertical drop, we explored the two well decorated chambers in the cave, and photographed the bones from several animals. But we could not see anything which looked large enough to be a bear.

The cave entrance consists of a steeply sloping sided pit before it turns into a vertical shaft dropping 20m to the floor. It appears to have acted as a natural trap, catching unwary animals who have lost their footing and fallen to the bottom. The animals appear to have survived the initial fall, but being unable to escape they eventually just laid down on the cave floor and died. Caves tend to protect things from natural erosion, or from being buried under the soil which accumulates on the surface. So bones like these can remain almost perfectly preserved for thousands of years.

Disappointed that we did not find the bear, we returned to the surface at least happy with an excellent photography trip underground. In the bar that evening we happened to see some photographs taken a couple of days earlier in the same cave, and there were pictures of a great bear skeleton just lying on the floor! How could we have missed that? After finding out where exactly it was located, we made another visit one evening later in the week. This time we found the bear. It is quite large compared to the other animal skeletons we found, but due to the bones having become calcified, it blends into the floor surprisingly well. We had to position our flashes at a low angle to cast shadows so that the skeleton stood out from the floor.

In addition to the photographs posted here, I took stereo pairs of all the bones we photographed in this cave, with a plan to generate some 3D images of what we recorded on this trip. These visits were to start a long association with this cave for me, and resulted in several further photographic trips to this special place over the following years.

Expedition Cave Photography

My second year caving in Matienzo in Cantabria, Northern Spain. These were some of the photos I took on a trip into Cueva Riaño.

Deep underground in one of the caves we were exploring is a passage named 'Cat Print Passage' after the discovery of what appear to be footprints from a cat in some otherwise untouched mud protected by an undercut on a bend. This was my attempt at documenting this feature as to my knowledge there were no photographs if it.

More Camera Practise - Ducks

Still learning how to use my long lens hand held with the tele-converter. This requires manual focus, so takes practise. Therefore a cooperative subject provides a great chance to perfect my technique. These ducks were swimming in the shallows of a flooded quarry in the Malvern hills.

Yorkshire Dales Landscape

So often I am in the Yorkshire Dales for caving, but rarely have I actually taken a nice surface landscape photograph. So when driving to a caving club dinner on a Saturday afternoon and the light quality being really nice I stopped the car to snap this view in Swaledale.

Aggy Courtesan

A serious cave photography trip deep into Aggy to photograph the fantastic formations discovered in the Iles Inlet extensions recently. With some route finding difficulties it took us around 5 hours to reach the formations, and a total trip time of over 12 hours. I did not dare taken my Canon EOS 5D on such a long and arduous trip, so these photos were taken on my trusty Olympus C8080 which has been used for all my digital cave photography to date.
These fantastic urchin formations are clustered on the ceiling in the same chamber as the Courtesan
They are packed so tightly together it was difficult to get a photo where they stood out from the background
This is the magnificent Courtesan formation. A stalactite covered in helictites.

The Cat from his level

A photo of the cat taken from his level. Exposed using the light in the room (which was a combination of the fire and some low energy bulbs reflected off the walls). The camera was resting on the carpet for this long exposure (0.3s).

More Garden Birds - Practising with the new lens

I've been practising with the new camera and telephoto lens again, photographing more garden birds through the kitchen window. I am very pleased with the quality of photos that I can get with this new equipment.

That's a lot of nuts for a small bird!
