PLANETCAVER

Welcome to the Planetcaver blog, featuring stories from caves and underground explorations around the world, from the point of view of a beginner caver. The Planetcaver has explored underground places in 30 countries and 486 locations (348 natural and 141 man-made). You can also click on the map on the left to see where in the world they took place.

There's also a "map of maps" -- a map of caves that I have drawn a cave map on on the right (139 maps). There's also a long list of those maps as well as a list of 3D models that I have created. The Planetcaver articles appeared originally in the Blogspot Planetskier series, at TGR posts, or at the Relaa website. See also the articles about skiing, urban exploration, climbing, cycling, flying, swimming, and saunas.

Tower and Cave in Alíartos
A random discovery while driving through Greece's small mountain towns. A massive hole by the road, with a tower on of the rock hill. This was so sudden that I didn't even think of registering the location or stopping. And I was in a rush to get to the ski area anyway.

Beach without sunshine The Cave of the Seals
Imagine summer. Imagine a nice beach in a southern country, like Greece. Way too hot! How about a beach in a cave, so that you don't have to get sun cream out? This, and so much more you can get in the Cave of the Seals, north of Corinth and Loutraki and on the Perachora peninsula. An hour from Athens.

3D-printing 3D-scans of caves
Can we copy a cave, by scanning it with an iPhone lidar, then printing a model of the cave using a 3D printer? The short answers is yes, but there's a lot of complexities, and it is not as easy as one might initially think.

I don't know what this is, but it looks somehow familiar...
Greetings from your sewer inspectors! This adventure in Ancient Corinth, Greece, started in a very promising way: why not visit a cave whose name is Σπηλιά «αιδοίο» της Αφροδίτης, or, Aphrodite's you-know-what? And I have to say, it does look very familiar, in fact it looks exactly like the Finnish Högberget cave. See below:

Cave inside the Tatra Mountains Belianska Jaskyňa
Wow, another cave country! Slovakia is I think my 28th country where I've been underground. Belianska Jaskyňa is the largest cave open to the public in the Tatra Mountain region in Slovakia. At the length of 3681 meters it is quite big. And, remarkably the tour actually is quite long, rising over a hundred meters in vertical as well inside the cave. And almost two kilometers long! One of the best walking cave tours I've been on.

Pećina Beli Kop
Pećina Beli Kop is a small cave in Sremski Karlovci, in mid-western Serbia, northwest of Belgrade. The coordinates are N 45.13654 E 19.85772. The cave sits under a sandstone cliff that appears to have eroded, forming the cave. The cave floor is actually a large sandpit itself, and difficult to walk up and down.

Caving images generated by DALL-E
Wow. I've seen DALL-E's pictures from other topics elsewhere previously, but now I tried it myself for caving. And since we just had the pre-Xmas party of our association in the cave, I gave the AI the task of imagining what it would look like. True to its style, the generated images are mixture of amazing with some very disturbing undertones.

Caver's club Xmas in a cave
The Finnish caving association, Luolaseura, has a tradition to hold pre-Xmas parties. This time we started it in a warm place ... in the Grottberget cave in Siuntio. And it was surprisingly warm, I guess because the cave entrance is lower than the cave itself. And with a dozen cavers in this small cave, it also heated up quickly. I really liked the old style oil lamps. And the cave dog!

Vantaa is too tight
We went for a short caving trip in Vantaa... visiting our old friend Kalkkikallion ketunluola. It is still a great small cave, dark and tight. But one of the other caves, Kalkkikallion matalan katon luola (the low roof cave) was even more interesting. I had been there before, and didn't want to go through between the two entrances. Now I tried again... and still didn't want to go through. The cave gets progressively lower between two rock layers, and just before exit it is less than 20 cm... maybe someone else wants to try?

Kipontie, what a wonderful Finnish cave!
Why look for limestone caves and stalactites, when in Finland you can find moss-stalactites? And besides stalactites, the Kipontien luola (cave of the scoop road) is an exceptionally nice experience. Most Finnish caves are cracks on a cliff or space under boulders. But Kipontie is a hole in the ground, on a more or less level surface, even if inside you can see that it is made up of cracks and boulders. But it is dark, it is tight, actually make that very tight, and downright claustrophobia inducing hell hole. Just like caves should be!

Schneefleckhöhle
Continuing my quest for using lidar in newest phones to build 3D models of caves. Here we have a scan of the Schneefleckhöhle, a 160-meter marble cave in the Zillertal mountains in Austria. The cave has been scanned with iPhone 12 Pro and Polycam, using lights and the phone mounted on a Benro selfie stick. Scanned segments were put together in Blender and used for fly-through animation. I can also feed the 3D model to my "Cave Outliner" software that draws a plan view map and cross sections based on the model. Lots to improve in various pieces of software, and scanning an entire complex form is very hard. While all of this is very experimental, bleeding edge technology it is also very exciting, and already offers some stunning views onto a caves.

Schraubenfallhöhle
Schraubenfallhöhle is a cave, an underground river. It starts from one raging waterfall of the Tuxbach dropping into a wide hole in the ground, and emerges a bit later to start another waterfall. It is located by the end of the Hintertux valley, right by the lowest lift station taking people up to the Hintertux glacier.

Jeskyně Postojna -- Czech Edition
Jeskyně Postojna famous, massive cave in Slovenia. We are on our way to a Jeskyně Postojna. But not the one in Slovenia... a smaller one in northern Czech Republic. This cave, Postonja cave, was named after farmers' shouts as they kept shouting for their sheep "wait little one" ("postüj malá"). While the cave is not huge, it was a very nice cave to crawl through. Soft, dry sand at the bottom... smooth, round surfaces, tiny holes to squeeze through. A great exploration, with also countless other smaller caves around in the so called Klokočské Rocks natural park. There must be thousands and thousands of holes here, wondering if everything's been researched and looked into?

Sutro Baths Tunnels
The Sutro Baths were luxurious swimming pools on the San Francisco seafront, in an almost all glass building, built in the 1890s. Complete with salt and freshwater pools, slides, and 30 swinging rings, and a springboard. It was served by two rail lines, one of these being the Sutro Railroad, another creation of Adolph Sutro, a famous engineer and industrialist and mayor of San Francisco! In the 1900s the facility fell into disrepair and it burned down in 1966. Today only ruins remain, including the pool basins, a settling pool, and tunnels.

Maanala - Manala
Went to the Amos Rex art installation today, on the topic of subterranean matters... with friends from the Finnish Caving Association. Only that it wasn't just about subterranean, it was underground things but also hell, evilness, and devilish matters. It took a while for me to understand this, because I of course associate underground things as interesting and fun, not as dark hellish situations.

Moaning Caverns adventure tour
Moaning Caverns is a limestone-marble solutional cave in Vallecito, California. It is about 200 kilometers east of San Francisco, on the foothills of the Sierra Nevada mountain range. The main show cave attraction is the 165-feet high massive hole, but the cave extends further down in smaller passages under the big room, getting to a depth of 410 feet or 120 meters. An adventure tour explores some of these parts, which is why I was here. But there are other interesting aspects of the cave as well -- at the bottom of the main room there's a large pile of animal and human bones, presumably from whoever fell down to their fate here.

Zagrebenje bunker maze
Croatian islands have had a military past. During World War II when Tito held his headquarters on the island of Vis. After the war, Vis was turned into a defense bastion, and only opened for foreigners as late as in 1989. Today we toured a maze of tunnels on the Zagrebenje mountains on the southeast corner of the island, connecting a number gun positions.

Make the trip to the airport count
Conference is over, time to head to the airport. How about an early wakeup, and trying to make the trip count as something interesting?

Running into an unexpected cave during travels? Very nice. To a show cave that was opened in 1646? Even nicer! We were on our way to visit the ski hills in the Harz region in Germany when there was a sign for a show cave -- the Baumannshöhle. Upon returning from skiing, we were able to visit the cave as well, just before it closed.

Cyclop's Cave
I had an opportunity to visit Cyprus this week, and, of course, there were also some caves. The Cyclop's Cave is on the south-east end of the island, a nice 23 m x 24 m cave with a sand floor and a thin rock cover above. Right on the beach, with great sunset views. But this is also likely not the "real" Cyclop's cave from the historic tales, that is in Greece.

Apartment Carved out of Stone
Coming back from the skiing on the Mount Olympus and Troodos Mountains in Cyprus, I was driving by an area that had reported some kind of underground passage. I stopped to find out what it was about. From the map it looked like it was near a road, but it turned out to be only near some kind of agricultural path, and a kilometer or two from the drivable public roads. Well, why not walk to the darkness on the first night in a country you've never been to...

Automatically generated cave maps from Austria
In August I visited Austria, and was able to hike to the Tischofer höhle and Hyänen höhle caves. Back then, I took 3D scans of the caves. Having worked with automatic construction of cave maps since then, six months later I'm now starting to have a capability to run these models through the Cave Outliner and get plan and cross section views out. Pretty interesting work, by no means done but lets see where this path leads us to!

Grafenloch -- also called Luegsteinhöhle -- is a cave on a massive cliff face above the villages of Luegstein and Oberaudorf. A smallish cave, maybe 22-25 meters deep.

Birthday trip, full of fun!
How much fun can you pack into one birthday trip? I started with a drink ... non-alcoholic, of course. And then things starting going faster after that: a sauna at the Oberstegen, continued with skiing on the Hintertux Glacier, went for a SUP paddling tour in an ice cave river under that glacier, and ended up climbing to the Grafenloch and Rossstall caves, and doing a 3D model of them. Not bad, and that was just the first day! Maybe for my next birthday I'll try to come with an active program.

I had been to Eispalast before. It is an ice cave that tourists can visit, 30 meters under glacier, near the top of the Gefrorene Wand mountain in Hintertux, Austria. But when I saw they had an option for trying SUP boarding on the river or lake in the ice cave, I knew I had to go again.

Kattilajärvi cave walk with Jarmo
Last winter I explored the far reaches of the Kattilajärvi on snow shoes, and found several new small caves. But also ran out of time to explore them further, and the heavy snow cover didn't make it easy to explore the boulder caves. I wanted to return during the summer, and now Jarmo and I hiked around the Lippukallio are east of Kattilajärvi. And wow, many new small caves, and we realized one of the boulder caves I had seen in the winter was actually quite big. Three levels, complex maze, shaky moving boulders... nice!

Looking for caves in Lohja's Linnanmäki in Karstu
The evening's excursion was to Lohja's Karstu area, in search of caves. The Linnanmäki is a high hill and cliff in Karstu, and the book Suomen Luolat notes that there are two caves on the hill. One was supposed to be inaccessible without climbing equipment. But as usual, the coordinates were inaccurate, so I ended up going around the entire hill, and I think found the other cave plus four other small roof/shelter caves.

Korpikylä ("Remote Village") is a region in Hyrylä. I was stopping in Hyrylä for other reasons, and looked on the map for an interesting place to go snowshoeing in. Korpikylä fit the bill, and after some searching for a parking place I headed out for a two-hour nice hike in snowy forest.

Kauniainen cave with a view
Cave of the sunset! I guess this just goes to show that no matter how well you know something, there are things you don't yet know. I did a snowshoes hike between Kauniainen and the Glims museum area, and came across a new cave!

More Kauniainen cave maps and 3D models
I spent Sunday biking and walking in Kauniainen's forests, mainly in the Kasavuori ("pile mountain") area. I wanted to visit a couple of small holes there are in the cracks and boulders of the rocky landscape on this "mountain". And draw a couple of simple maps about them, and use my new iPhone 12 Pro to record 3D models.

New cave (sort of) in Kauniainen
While cataloguing Kauniainen's tiny caves (if one can call them that), I came across another one. A small tunnel between two boulders. The tunnel part is maybe 3 meters (though with a small crack at the top for some part of that).

New Kattilajärvi caves
I was hiking around on my snow shoes, going around lake Kattilajärvi in Nuuksio. I was there for the sake of a nice walk in the winter weather, but also wanted to check out the many cliffs for possible caves. I've been here before, and saw for instance a wonderful roof cave. But then I came across a big cliff with a number of caves, not reported by others as far as I can tell.

Strange rock
Tero and I were on a trip... while caving was not the main purpose of the trip, as usual I also wanted visit a cave. A promising-looking hole at the Pyhä ski area turned out to not be a human-sized hole. But while returning to the airport in Rovaniemi, we drove south of the city to look at Tapulikallion onkalot (Tapulicliff holes). We founded a very weird, large boulder.

Ramunder's stone
Right in the middle of Tammisaari there's a classic "stone table", Ramunderinkiven onkalo (The Hole of the Ramunder's stone). Stone tables are stone formations where a rock sits on other stones. Ramunder is the strong man of old tales, and the story is that he threw a large boulder to crush some giants, giants that are now the stones holding up the boulder.

More cave searches, based merely on the name
Inspired by Ralf's observation of cave-like names in the countryside, I searched for more caves from the Finnish map databases, and came up with some more placed called "Luolamäki" or cave hill. This time near Nummi-Pusula, Lohja, and Vihti. Jarmo, Ralf, and me set out to explore... with no prior knowledge of any caves in this area reported anywhere. Not in the book of Finnish caves, not in Retkipaikka, nowhere.

Paimio cave search... on a swamp???
There are a lot of interesting data sources for searching for new caves. There are databases at the national geology research institute [1, 2, 3]. There are reports and books of boulder fields [4,5]. There are websites [6, 7, 8, 9, 10]. Old newspaper keyword searches [11]. And regular maps [12]. But in addition, there are also names of places. Ralf had found the names Luolaniittu (cave field, on a small hill) and Luolassuo (cave swamp, an actual swamp) in Paimio. I have to say we felt pretty silly standing in the swamp with all our caving gear.

Caves in Nuuksio's Katajasuo
Research pays off! I wanted to explore more boulder caves, but where to find boulders? I kept looking for data, and it turns out the geologic research institute had made a listing of the most valuable boulder fields in Finland. One of them was nearby, in Nuuksio, so I headed out to investigate on Sunday. No caves had been listed at that spot, but the report already made some promises about cave-like holes between the rocks. And a 50 meters wide and 10 meters deep field! I was hooked. Although it turned out the location was listed after all in the book of cave in Finland (albeit with a different name).

He had made a visit earlier, and saw an incredibly large cave hall. Still, I had not realised how big it was. Over 100 meters in free height, and 240 meters to the natural opening at the top.

Replica Cave
While in France, I happened to get a number of brochures for tourist caves. One of these brochures was about the Chauvet Cave, the cave with earliest known paintings from 30 000+ years ago. But, that cave is off limits to visitors, so they built a replica of the cave nearby!

Deadly bunker trap
Well, that was dangerous. We're very careful when we visit blown-up bunkers. But, we did not expect intentional traps, at least not recent ones. Next to a bunker in Siuntio, Jarmo almost fell into a 5-meter deep well that was covered with fresh tree branches. Would he have hurt himself if he fell in, or even if not, would he have been able to get out if he was alone? Who does this sort of thing?!

This is a difficult bunker to get to. Not because being covered by dirt or blown up. But the whole area is guarded by, well, people who do not like other people to visit their part of the country.

Faerly Hole in the Jenny Jump Forest
The "Shades of Death Road" address was odd, but the day and the nature was wonderful. I found the Faerly Hole cave easily on the shores of the Ghost Lake, and walked in. It wasn't before I had crawled through a small hole that I realised something the rock walls above me were covered in layers of spiders and crickets. Thick enough to form a dark mass. And that mass had now awakened and was dropping and jumping on me.

A Kilometer Inside
This is an exceptional opportunity that only opens once a year. Janne and I are crawling in the cave, guided by friendly cavers from the Swedish Speleological Association. We get to see amazing things, from stalactites to "Inre Sjön", a small lake (or rather, a pool) a kilometer into the cave.

I want to take you to a special place. Janne and I have spent there over 20 days by now. And every day of exploration rewards us with more finds. It is nearby. An old friend. But did we know all of its secrets before? I certainly didn't. Caves in Finland are small. What if I told you about a complex system of caves, with hundreds of meters of tunnels and fifty entrances, including one that you can drive a boat in?
