Yauyos report


When we headed south we drove via the Cordillera Blance to get a look at a few peaks. Alpamayo was discussed and at least 3 members of the crew were keen for bagging a 6000m peak. However, we decided that on our next expedition we may be a more setup for it so we carried on south. When we got to the Rio Canete valley we were all stunned at the beauty of it and also that the road was in such good nick! We passed up through Alis, Tomas and Tinco and kept heading north towards the Abra Chaucha pass at 4700m. Just before the pass we noted the Puyo valley to our right and also the amount of shafts we could see there from the road. Game on!

We turned right on the Saturna mine track and rumbled off, bouncing around. After about 10km we turned right at Alalac and 4WD back towards the limestone. We met the local family lad Abel who had walked out to meet us and said we could camp on their land, BASE CAMP SORTED AT 4600! We were in a great location – over a 4800m ridge to the Puyo valley and within walking distance of 10-15 large shafts that Abel had told us about. We even had a decent sized stone and thatch hut for my bivvy bag!

From this excellent base camp at an altitude similar to the local cave areas we started a methodical approach to looking at the block. We prioritised the large shafts and of course Tragedero Puyo and Cueva Puyo that Chris Densham, Nick Hawkes, Ian McKenzie and Pete Whitikar had left with question marks in 2004. With the new 4 guys in the area slowly acclimatising to get to our high camp we headed to Tragedero Puyo first.

The first thing that I noticed on my recce of the Puyo entrances was that the 2004 GPS data was wrong in it’s elevation. The “old boys” had noted the entrance at 4570m above sea level which carried it to number 4 on the world’s highest cave list. My Garmin (later confirmed by 2 separate Suunto altimeters and 2 more GPS) read the cave to be at over 4681m. The same was noted at Cueva Puyo. There was much discussion in camp that night about the Americans “blurring” GPS data after 9/11 and I did wonder if that could be true. Either way, the Puyo valley’s caves and those in the same block to the north and west of the valley are certainly the highest explored group of caves in the world at the moment.

We rigged the entrance shafts utilising our drills and drop ins rather than the old boys who had used spits and Guillaume and I did the push. After 122m (old boys got to -107) the cave went to a horrendous tight squeeze into water. I pushed it with the hammer and drill and nearly couldn’t get back through from the other side. Maybe somewhere else in the world the cave would get capped and pushed but not at 4600m in Peru! The 2 pitch heads that were reported to be awkward in 2004 were certainly nasty but we do think our acclimatisation made our trip slightly easier.

Cueva Puyo was next and what a cave! We got to where the old boys had left a 20m pitch and dropped that through some big stuff into a huge rift – 100m deep. The draft was insane – we all got extremely cold exploring this cave and the temperature was measured to be 2 degrees C. After the rift the cave went to a tight hole and a small climb – both ways found to be impassable. Cueva Puyo was measured to be around 190m deep with some impressive sized passage compared to the Tragedero 60m away.

We started to methodically drop shafts throughout the area concentrating on the block to the north and east and the block to the far east next to the road. All of this limestone is the same as the Puyo caves but is seperated by cols, ridges and peaks. To the north and east we dropped 50 odd shafts – mainly between 50m and 115m in depth. The pit bashing was amazing fun at this altitude and in such a setting. Frustratingly none of the caves went. To the East (next to the road and through the Abra Chaucha pass) we dropped around 20 pits/shafts/caves all around 70m deep. Much frost shatter was encountered – new for some of us and again we couldn’t seem to penetrate through the breakdown. Suicidal Tendencies and Minor Threat were both caves to note in this area – both large with congregating shafts and development making survey drawing a nightmare! Some of these caves we were anchoring to the Hilux’s roll cage!

After 10 days and 100 explored caves we decided to move on. Whilst the team was out caving Nic, Guillaume and I had taken the time to go and check out “The Tomas Block.” We had driven down to Alis, up to Huancaya and back through a road that doesnt exist on the map to base camp. In the middle we had managed to ditch the truck at 3550 and hike up to 4900m in a day – exploring the massive above Huancaya. Lots of sinking water, caves and shafts were noted for a return trip. We also discovered some caves around Cerro Shacoc Mach’ay, Cerro Fierro Mina and Lago Quillcay. All of which were worthy of a return trip. Below Lago Quillcay the sink was noted to drop straight into the bedding and sucked air extremely well – immediately branded El Chupedero!

We discovered a lot of stuff through this area. The Cerro Shacoc Machay area was extremely interesting. We pushed several caves all part of an obvious system and even had a night out digging. Real stream ways with real water were not something we had been used to in the previous weeks down south! Hannah and Rob even climbed a VDIFF route to claim their first 5000m plus peak! Chupedero kept us busy for a few days and we even got to recce the fantastic Rio Canete sink and resurgence – what a place to return to!

Our trip out to the stuff above Huancaya was pretty tough. Carrying 25kg packs we walked from 3550 to 4800m and set a camp for a few days. We explored all of the leads and even a cave at 4862m – the second highest in the world. We even found Inca human remains in a well worn (polished floor and “steps” through the cave) little high cave above Huancaya. All leads were finished with a couple of shafts going to over 100m depth and plenty around 80m.

Overall the expedition has been very successful. We have kept going with the great work started by Nick Hawkes and his lads and have checked out several more areas, recording our discoveries and will publish them for the wider caving community to use. We have got several leads to come back to, one of which is probably the most serious vertical river cave I’ve ever seen which will take much planning (and many sleepless nights) to tackle. It involves around 3 cumecs of water dropping into a boulder ruckle with a black hole behind it. Mess up the rigging and BOOM! We plan to return with a strong team and carry on the work, but for now our energy will be focused on drawing up surveys, congregating data, crunching numbers and sorting through thousands of above and below ground photos. We would like to thank Les Oldham, Jhon Human and the people of Peru for their wonderful hospitality and if you’re interested in reading about our exploits in more detail please watch this space as it updates over the coming weeks.

Expedition success

Wow, what an amazing expedition with 10 superb cavers whose company has been intense, entertaining and emotional! I guess its up to me to provide some sort of summary or conclusion, but to write a conclusion for one of the most exciting and hard caving areas in the world would be sad and indeed stupid. A summary for this years trip would be more appropriate. It feels like we have only scratched the surface of entertaining the potential in Peru, unlocking it, enjoying it and developing a project for the future generations of caving to exploit.

Essentially the expedition took a group of highly experienced guys from different backgrounds, cultures and experiences to visit some of the toughest terrain in the world at an altitude to be respected by all, and here we decided to push hard vertical caves, some with active water systems in them in temperatures close to 0 degrees. In doing so we have completely re-written the worlds highest caves list, started a new chronology of  caves in 3 districts of Peru and have all used our current underground skills, developed them and shared them with an international team. As our kiwi brother Adam would say – it has been a complete mash up of knowledge, skills and technique. An international team bridging gaps in ideas, tools, motivations and prejudice (we had 3 Canadians AND 3 Aussies on the trip!) took on the challenge and completed it with little ego, lots of enthusiasm and huge amounts of good humour.

We started our Peruvian soiree in Lima where we kitted up and drove to Cajamarca where Peruvian caver Jhon Human had passed on a glowing lead 6km north of the proposed Conga mine site. Jhon’s involvement in the Peru caving scene has been lengthy and he is extremely knowledgeable and enthusiastic about the long term caving project here. He was lucky enough to join Nick Hawkes et al in the Sima Pumacocha epics in 2001-2004. These highly successful epics were the inspiration behind the 2012 trip and I feel lucky to have been involved with some of the participants from those expeditions. In Cajamarca we drove out to the Pampa Verde site where the large Rio Jadibamba sinks into the limestone at the contact forming an impressive sized entrance and luring us that far at least from our various arm chairs in various continents. On arrival we stayed at around 3700m on Senor Andreas Mateo’s farmstead, an ideal location 400m from the main sink and COMPLETELY surrounded by enticing limestone and various huge sinks/dolines. It was however apparent from the get go that the water exits the good rock a km away and disappears off down the valley towards some somewhat finer looking karst. However, we had come to do a job and do that job we must!

The system was full of water – adding swims and scary traverses above deep pools of icy water making the cave very sporting. The main system was around 800m long and 40m deep. In the opposite direction from camp 2 other entrances into the system were explored and surveyed with active streamways assumed to be the same water, several other caves were explored and mapped on the hillside to the south and west of the main sink. We tried to follow the valley to an impressive line of dolines 4 km east of our location and right above the steep contours into the lower valley below but unfortunately the locals had no comprehension of speleology and assumed us to be evil right wing miners who were there to steal their water, resources and suck the life from their families for our own financial gain. After some extremely serious conversation and frustrating negotiation, the locals declared that we would not be allowed onto their land and the argument seemed pointless in pursuing. We decided our efforts were wasted here and would be best spent elsewhere.

Back in Cajamarca we met the lovely local head of tourism Maria Victoria Vilca Alfaro (Vicky) who told us about potential areas to concentrate our efforts on a little further south in the Cajabamba district. Within 48 hours we were at her families farm in a remote valley where Nic and David took some horses and rode off in search of cave and glory, this was one mode of transport I for one had not prepared for! The local caves were not in very good limestone and our search continued, warmed by the welcoming local people and their generous hospitality.

We headed south again to a more limestoney block above the town of Cajabamba proper. With a local guide we were shown some horrendously scary roads that led to a fantastic plateau. for several days we explored “el chorro” (the squirter) and a few side caves around there. El Chorro is a strange overflow cave full of bats. It involved a VS climb to the entrance (one bolt drilled!), some crazy bat attacks and some good bolt climbing and sporting cave. it was dry for the most part and is thought to be part of the system connected to the lake to the north west. it was around 770m in length. Other caves in the area were explored and surveyed and we eventually headed to the falls that some from the lake on the western plateau. Here things got interesting. We found 12 vertical holes, 2 with 10 second drops in a very interesting location, but due to time we didnt get to explore them. It was time to head south to pick up 4 new team members and drive to the expeditions main objective in the Yauyos district…


more to follow later


Well, we are back into Lima from our 3 weeks or so in Yauyos. What a time, and interesting situations!

We pushed hard, dug, had some chest hurting squeezes, ducks, multiple 20+km hikes (with 1000+ m elevation gain and loss’), and we made it back. Team members experienced sorejche, snow storms, exposed climbs, cold swims, etc to name a few of the many hurtles faced with while tracking down those elusive high altitude caves. Some of which we found adjusted the normal expectations of our  speleogenisis (ie. a 120+m long active stream cave in a tufa dam and granite boulders).

Camping at 4600m did give us an advantage once acclimatised. So we were better equipped to cover more ground, and prussik out of the numerous shafts the team explored. On average they tended to be -50+m, the deepest explored was -115m. We also explored some horizontal caves, one note worthy cave consisted of pheratic passages displaced along the bedding as if the upper section of the tube passage stayed put as the lower section shifted sideways  (or vise-versa) to create an”S” shaped cross section. All members of the team has repeatedly pointed out the tortured geological history of the Andies adding an other challenge to the high altitude caving we were here to do. We did get to experience this first hand on more than one occasion when we had some minor earthquakes.

On finishing up some of the 2004 expeditions leads we noticed that the elevations were out by 106m (they are higher then previously recorded), attention was then turned to thoroughly prospecting and pushing the area. We then began some reccing far a field and probing into areas that have held our interest for a while. Some of the discoveries ranged from ancient human remains to a caving project that will see some of us return for some of the most serious and potiential dangerous caving of our lives.

We have now shaved off our expedition beards and are dressed in clean clothes (most of us) slowly trickling through the Lima airport to go home to our other lives. We will all carry with us a warm place for Peru caving. Some of us will return to share this place with others. An amazing experience with an amazing group of people, I am hoping I get to meet them on an expedition, or in a cave again.

Cheers everyone,

Nicholaus Vieira

Crazy Caver


Cuevas del Norte


I think everyone on this expedition would say the very same thing if you asked them about the first half of the expedition. We had our difficulties from crazy mountain roads, difficult terrain, Swimming passages (at well over 3000m), a bat cave, getting kicked out of areas due to the political tensions, so on and so forth. We chased up leads by vehicles, on foot, and even a crazy horse back recci trip that involved returning in the dark and hail 10km on steep steep terrain.


We are now about to leave and prepare for the next (and highly anticipated) part of the expedition, a return to the Puyo valley and area.


I have up loaded some photos from the recci, caving etc in the Gallery called “Cuevas del Norte”.

You will only see a small part of things, and unfortunately can not hear the giggling that came with swimming, or Adam’s remarks as he pushes into new territory with bats wizzing by his head. Hopefully they will entice you to brave your own 6+hr marathon horse trip in the steep mountains of Peru to find that cave that will leave you as breathless as the altitude.

Stay tuned for more, I hope I will get a chance to share some of the stories soon.

Bats Regards,



Have never felt so out of my legue… The energetic wisdom and knowledge this crew is amazing… Copios amounts of enthusiasm will only get me so when it comes to caving with these guys who live and breathe it. If there was ever a time to embrace the way of the sponge and soak up as much of what these guys have to offer in the shortest time possible… It’s now! Very honored to be a part of such a humble caving team on this epic Peru 2012 Expidition!

Sleeping in Hilux’s

So for the last two nights in a bid to keep an eye out for our gear (in the back of the trucks), I have been sleeping in one of the Hilux’s (Andy also did the same for the first night).

Last night I was woken to a crowd moving through the streets yelling and shouting slogans. Considering the state of emergency has been lifted last week, and all of the “Conga no va” graffiti everywhere, this is adding a new element of cave recci for me. The funny thing is the vehicles we are using are the types used by mining companies.

On a separate funny note Guillaume and I had some funny looks when we were trying to buy a pressure cooker, white gas, and a machete. Apparently we looked the part?

This morning while shopping we witnessed two peaceful demonstrations, a sign of things to expect we plan on being careful.

On our way North – At Cajamarca

Hi Guys,

Had to stop over in a hotel when we had a longer day than expected, figured a quick post was in order.
We’re had a great couple of days and so far have managed to get to Cajamarca.

The changes in the environment around us has been amazing and not what most of us were expecting. We’ve also found the roads here really exciting, or freakishly scary! Its a toss up.
Its not uncommon to have to hit the shoulder of the road to allow a bus to over take a trunk on the wrong side of the road.

We’ve uploaded some new photos to the gallery! Checkout the Travelling North Gallery

Till next time!

Last Day in Lima

Today is the day we’ve all been waiting for. The day we leave Lima and head off North into the country areas.

The last few days has been a hive of activity. From visiting supermarkets for food supplies, visiting local markets for cheap pots, pans, died fruit and nuts to testing of the stove fuel found at a local hardware store.
But at last we are ready.

Our expedition trucks have arrived this morning, nice almost new, Toyota Hilux’s! Much better than I think most of us were expecting.

This maybe our last post for a while, possibly as long as three weeks until we return for the second half of the trip.


Until then…

The Team – Lima Peru 24/9/2012

Lima, midnight 20/09/12

Once again amerced in a foreign country learning a new language and an amazing culture. Andy and I landed here in Lima yesterday at 12am, dropped our bags off and went to see what our local hood of Mira Flores had to offer… wasn’t much but we managed to drag out the excitement and smiles till about 8am, finishing up at one of the most amazing food markets I’ve ever been to! The colours, tastes and smells were outstanding! Finding this goldmine at the end of a long night out wandering the streets with a well seasoned english drinking chef has surely assured us some amazing kai for our journey.


Today has been mostly recovery with a couple of delicious feeds from our new local favourite…. La Lucha… burgers and an energy about the place to die for.It’s nice to be travelling with someone after a few solo trips and from here on out our numbers only grow… So happy to be here and love what Peru has to offer so far! Let the good times roll…

First group touch down in Lima Peru

Andy and Adam from Sydney have recently touched down in Lima Peru. They report annoying jet-lag but they are otherwise fine and are making the final in country preparations for the trip

The remaining Sydney members Al and myself will be leaving in just two days (Saturday morning) Sydney time.
