Although this is not cave related, I am posting it as Bear Grylls has been mentioned in my blog.
In May 2016 it was announced that ITV has cancelled Bear Grylls TV show, Mission Survive, after two series. See The Guardian report, 31 May. The reasons are due to a fall in ratings.
As far as I know, none of the episodes were filmed in caves.
Bear Grylls has received many negative comments from international cavers in the past due to his reckless / dangerous attitudes to caving - see labels on the column to the right.

New cave art found in Spain in Atxurra Cave
New Palaeolithic cave drawings have been found deep in a cave in northern Spain. About 70 drawings were found 300 m underground in Atxurra Cave in the northern Basque region, in northern Spain. The engravings and paintings were found in 2014 and featured in the news in May 2016.

Underground London - sinkhole near Woolwich
Not really cave related, but it is something underground!!! Early on 12 May 2016 a sinkhole appeared in a road in a residential area near Woolwich in London. A car partly disappeared in the hole at Charlton.
A possible cause is the fact that the underlying material is chalk and there could be cavities, also the area was mined during Victorian times so there could be tunnels underneath.
According to The Telegraph, " In recent years large holes have been discovered across the borough, which experts have blamed on underground chalk caverns and disused mines which are “littered” across the district."............. "While officials from the Royal borough of Greenwich council assured residents that the hole had been “stabilised”, a 19th century report recovered by this newspaper suggests that the entire area may be precariously resting on top of a series of underground caverns.
Published in the Kentish Mercury on 24 March 1849, the article reveals that rail workers excavating the South Eastern Railway discovered a large crevice underneath Maryon Park, less than a mile from where Thursday’s sinkhole appeared.
It read: "during the operations... they came upon a cave, of considerable dimensions, cut in the chalk and flint rocks.
"A great quantity of sand has fallen at one end, blocking up the side from which it has apparently been entered, and the workmen are now busily employed in shoring up a part of the roof of one of the chambers, the railway passing over its entire breath."
It is the second sinkhole to emerge in south east London in just over a week. On May 4 a sinkhole appeared outside a house in Plumstead.
Now there is concern that property prices will fall after news of these sinkholes.
“Greenwich is one of the most expensive land areas in Europe, but in recent years six deneholes have been discovered in the area around Maryon Park alone,”.
Deneholes are medieval chalk extraction pits and are mainly found in Kent and Essex along the lower banks of the Thames.

Ray Mansfield RIP
My very good friend Ray Mansfield sadly passed away on 6 March 2016. He was a well known caver in his younger days, and will probably be best remembered for his bibliographic work, especially BCRA's bibliographic index Current Titles in Speleology. He had an amazing memory and was able to recall facts at a moment's notice.
I'm not in the right frame of mind to write more at the moment, but see some comments on the UK cavers forum.

Bear Grylls in negative news again
In recent years the emphasis of many TV documentaries seems to be on presenters tackling dangerous animals or performing dangerous stunts, especially in caves. Bear Grylls is one such presenter.
A few years ago he was criticised for killing bats in China.
More recently there have been programmes in which he goes into caves, jumps into rivers etc, and never wears a helmet, has inadequate lighting and doesn't seem to take any safety precautions. Again I have posted this on my cave website.
The latest upset was after a programme was aired on British TV of him caving in Yorkshire. In "Britain's biggest adventures", [ITV , Part 2, 2015, shown Sept 2015. Nutopia and BTV] after abseiling at Malham Cove without a helmet, he goes into Long Churn Cave. We see him going through a section of cave alone, with a single torchlight and no helmet. Then he meets up with an experienced caver. As the cave begins to flood they have to go out.
It seems to be that Bear Grylls often does reckless things, presumably for the TV audience.
A few days after "Britain's biggest adventures" aired, the Yorkshire based Cave Rescue Organisation made a complaint about the programme. This was detailed on Grough, I will copy some of the article here -
Cave rescue team complains over 'horrifying' Bear Grylls TV programme
Bob Smith, Editor
Monday 28 September 2015
A rescue team has posted an official complaint to television bosses over scenes in a recent programme featuring a renowned adventurer.
The Clapham-based Cave Rescue Organisation said last week’s episode of ITV’s Britain’s Biggest Adventures with Bear Grylls showed a total disregard for safety in the outdoors.
The rescue team’s chair Heather Eastwood has written to the channel expressing horror at some of the activities the star of the programme undertook.
Ms Eastwood said: “As chair of the local rescue team both myself and many of my fellow team members were horrified to see Bear Grylls show a total disregard for safety in the outdoors especially in relation to water and caving.
“Bear Grylls is Chief Scout and is an inspirational figure to many young people but both ITV and Bear Grylls himself have shown a total lack of responsibility by portraying some of the activities in the light that you choose to do.”
The programme, second in a series being currently screened, was set in the Yorkshire Dales and showed Bear Grylls abseiling down the 80m crag of Malham Cove, to meet climber Steve McClure half way up.
But the two activities that concerned the CRO are when the adventurer tosses his rucksack into the water at Stainforth Force before performing a backflip into the water, and heading into the Long Churn cave system near Selside without basic equipment.
Before stepping into the cave system with no helmet or protective suit and with just a handtorch, Grylls says: “Water levels are rising. This adventure was about to put all our lives in danger.” The commentary said it had been raining non-stop for 24 hours.
The television star, his underground guide Phil Murphy and the film crew are seen to make a rushed exit from the cave. Bear Grylls says: “We’re in genuine danger of being swept away so, for safety, we have to switch the cameras off.
“All of us make it out just in time.”
The Cave Rescue Organisation chair said in her letter: “Climbing up waterfalls shows not only a total disregard for the environment but failed to mention the dangers of water in general let alone how that danger increases in waterfalls.
“For those of us who know the area in question we are well aware of the power and dangers of the water shown even in dry conditions and have had the misfortune of being involved in difficult rescues in those areas.
“As for your portrayal of caving and cave exploration I am struggling to express my horror.

The Two Million Year Old Boy from South Africa
New : The Two Million Year Old Boy [Natgeotv 2011]
A 2 myo clavicle bone belonging to a pre-human boy from a previously unidentified species: Australopithecus sediba.
This was the discovery of the century, finding a new species.
On 15 Aug 2008 Lee Berger and his son were looking for fossils in the World Heritage site 25 miles from Johannesburg. It is known as Cradle of Humankind, because of the pre-human fossils. Many years ago the area was mined by gold prospectors and many caves and rocks were blown up. In a small depression in the Malapa Valley, Lee's son found a hominid clavicle in a rock, and later the lower jaw and a canine tooth. They were from a male child dated 2 myo.
6 myo humans and chimps shared a common ancestor. Australopithecus started walking on 2 legs. But it is not known when Homo appeared as there is a gap in the fossil record, between 2.5 - 1.8 mya. Very few bones of pre-humans have been found, only about 3000.
100s of bone fragments were found in blasted rocks, from animals such as sabre tooth cats, hyena, antelope, mice, rabbits etc. More finds were made, a humerus, scapula and 2 teeth. These were from a second individual. This was an adult female about 30 years of age. Could this be a mother and child? They were 2 hominid pre-humans and named as Australopithecus sediba. They had a mix of modern and old features.
Before this discovery, less than 10 hominid skeletons had been found. The new bones were very different from anything found before. A scan of rocks revealed a skull inside on. This was from an entirely new species as it didn't match anything known.
A lab was set up to make casts of the bones which would be available to researchers all over the world.
Human evolution has not occurred in a straight line as there are many branches and Australopithecus sediba contains old and new features. This new species had an ankle like a human with an ape-like heel bone. It had modern hands with ape-like arms, so could walk upright but still climb trees if necessary. It had a very small brain but it was reshaped to look more human than ape.
It is not known if Australopithecus sediba is a direct ancestor to Homo sapiens.
There was a clue as to how these hominids died - bones from both individuals were unmarked by predators. There were no tooth or impact marks. The bones were well preserved in limestone. Many hominids died violent deaths e.g by animal attacks. So how did these ones die? The boy had 2 broken bones on the forearm so could he have fallen. Today the cave is just a hole in the ground, maybe it was deeper before. Maybe the hominids were searching for water and fell down. Animal bones were also found. There could have been a flash flood which buried all the bones together. But the site was disturbed by the gold miners centuries ago.
Excavation of the site began. The tibia of a 3rd individual was found, a 2nd adult. Then some from an infant about 18 months old. Possibly a family group.

FIRST HUMANS: THE CAVE DISCOVERY
In Autumn 2013, 2 cavers Rick and Steve found a new previously unentered chamber deep in Rising Star Cave near Johananesburg in South Africa. Lee Berger, a professor of palaentology at Witwatersrand University lead the research which revealed the bones were from early hominids.
There was a gap between known specimens of Australopithecus and Homo erectus, 2-3 million years ago. Australopithecus was an upright ape, with a smaller body and brain than Homo erectus which was more human like.
Lee Berger called for skinny scientists who could negotiate the narrow passages to the new chamber. Cams were set up throughout the cave, using more than 2 km of cable. The position of the bones was mapped by laser scanning.
In 2008 Lee Berger had investigated the nearby Malapa Valley. On 1 Aug 2008 his son had found a hominid clavicle in a rock at a small cave/hole in the ground. It was well preserved in the limestone layers and dated to 1.97 myo. It turned out to be a new species, Australopithecus sediba. This discovery ended the gap between Australopithecus and Homo erectus. The bones were found to be from a female and a child. A complete skeleton was made by scanning and 3d printing. Tartar found on the teeth was tested and showed microscopic remains of many different plants such as grasses, wood bark and fruits. This indicates a diet similar to today's chimpanzees. It suggests that ape-like forest dwellers evolved into humans.
Back at Rising Star, the hip bones showed an upright but primitive gait. The jaws are more Homo-like. A piece of skull was definitely Homo and of a new species. Careful collection of the bones resulted in more than 2000 fragments from 12 individuals. This is the first new species between Australopithecus and Homo erectus to be found in abundance. The bones showed human-like feet, hands and teeth, which means they interacted with the environment. But the trunk and brain was more primitive, with chimp-like arms, long legs and a small brow. The tiny brain was only one third the size of a human bone. The legs and hands are part of our genus. But they are still close to Australopithecus.
There were no other animal remains in the cave. This is unheard of. Normally all 'human' finds are mixed with bones of animals. So how did these Hominid bones get into this deep, inaccessible chamber in Rising Star? It seemed to be a cemetery population. There were no signs of predation, no flow of material into the chamber, so were the bones put there? The brain is only slightly larger than that of a chimp, so could they have purposefully disposed of their dead? This would suggest highly advanced social behaviour.
This species could be an evolutionary experiment, as evolution went down many branches. It all adds to the story of our origins and fills in the gap at the start of our genus.
