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). Full story

Kirkkonummi Cavelets I realised last week that I need exercise, and sunshine. Today's exercise was to go caving in Kirkkonummi. But I didn't want to visit places that other people would likely be in. So I took the approach of visiting forest areas where there have been NO caves listed. Full story

Caver's meetup. Virtually. What a wonderful experience - forced to not not have in-person meetings, all kinds of organizations are realising that their meetings *can* be done over network connections, and that the results are often better. We just had a caver's meet-up in Finland, and we chatted longer -- six hours -- than we ever have and had many more people participate than before. Full story

Grotta di Frasassi This week I'm on a tour through Italy with Janne. I had mentioned this to Tero, who suggested that we visit Grotta di Frasassi east of Ancona. 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.

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?! Full story

The Korkberget Files 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? Full story

Monttukrouvi This lazy Saturday's program for me and Janne was to visit some of the bunkers and moats around Helsinki's WWI defence structures. There are plenty of these structures, sadly all slowly rotting away. Historic sites, officially almost forgotten and certainly not cared for. Full story

Anti-Gravity Lift Towers The Swiss are clever innovators. The latest example of this that I saw were the lift towers in Saas Fee. Floating in mid-air, not standing on ground like regular towers. Anti-gravity in action! Full story

Srsly, Smearing Caves with Vaseline???!! We had a disturbing visit to a cave today. Somebody had not only blocked access to this cave, but also smeared vaseline all over the cave, spread broken glass, and so on. Sigh. Full story

Cave Surveying Course We often have just coordinates. While Finnish caves are small, they are often also non-obvious, mere collections of holes under boulders. Would be nice to have a map, to even know if we're in the right hole. Full story

Smuggler's Cave, Salo Salo, southern Finland. More than an hour away by car, and we've been in the forest for an hour now. The cave is nowhere to be found. I have coordinates, but in the wrong coordinate system and Google isn't co-operating to interpret them in the right way. Full story

A Pile of Rocks Imagine rocks thrown together, all sizes all the way up to house-sized boulders. Korkberget doesn't get more than a brief mention in "Caves of Finland". But it is one of the biggest caves in our area, and quite a maze. Full story

Lost World The sun is still bright, but the environment is getting strange. Fog is engulfing us. Plants are starting to look pre-historic. And I'm hanging from a 100 meter rope, above the Lost World, a cave system in Waitomo, New Zealand. And it is starting to look like my landing spot is in the river at the bottom of the cave.

Dos Ojos I like lazy Saturdays. The ones with no meetings, and planes not leaving until the evening. And no plans, other than having a swimsuit and wanting to visit some natural pools in the warm weather. But I ended up seeing incredible cenotes, colours, and diving in the world's 3rd longest underwater cave. Full story

Underground Skiing Does anyone remember the arcade game where you stood on skis? I loved that game, and one of the interesting tracks in the game goes through a cave. Ever since playing the game I have wanted to experience skiing underground. This week I was visiting Alpe d'Huez, France, and my wish was fulfilled. The "Le Tunnel" slope begins with a 200 meter tunnel through the mountain. And then continues as the most difficult black run the ski area has to offer. Full story
