This summer I managed to write another article to the cave radio expert group's journal, the CREG journal. This time the article was about cave-outliner, and turning 3D models into maps, slices, and plan views.

We continued the sampling of the best Finnish caves on our weekend tour, as well as played more with the nice lights we had. (Previous light story was here.)

If your caving friend was coming over for a weekend, what would you show about the Finnish caving scene? Here's our menu for a caving buffet, covering everything from ice saunas to block caves to cracks in granite, mines, limestone caves, to salmon meals to ... did I already mention saunas? Not to forget Sibelius for dessert!

Korkberget is my favorite local cave. Also one of Finland's largest block caves, even if you don't get to go very dark while going through the cave; in most places you can see entrances and light between the boulders. But it is a wonderful sight, a great squeeze exercise, and nice back massage. And clearly an opportunity to practice much needed flexibility by the cavers :-)

A canyon. A wonder of nature that I did not know existed in Finland. Amazing, truly amazing green views! A place so secret that I do not wish to even tell its name or coordinates, for fear of leading more traffic to this delicate natural place. The place is near Turku, however. Let's call the it "Kaarinan rotkoluola" (Kaarina crack cave). You may ask how we knew about this place. We had a friend with us with knowledge... so here we were.

Our first stop on the grand tour of southern Finland caves was in Turku, in the Luolavuori cave (The Cave Mountain Cave :-) ). We ended up trying for fun various lights, an oil lamp and a new Black Diamond headlamp that supports not just white but also red, green, and blue light. Very nice effects!

As part of our exploration trip to the Njiellalanjávri area, we scouted all signs of limestone around lakes Njiellalanjávri, Toskaljärvi, Veajetjávrrit, and Láfoljávri lakes, and the mountains in between. In some cases limestone was easy to identify, known to be limestone, in other cases it was not so easy to identify by non-experts. But we think we made a reasonable analysis, and found quite many places where there is at least potential limestone. There's plenty of loose rock pieces that are clearly limestone, but the more interesting target for us were ground rock layers. Or larger collections of potential limestone rock pieces that might indicate a ground rock layer would be somewhere nearby.

Last week I went with Jarmo Ruuth and Duncan Simey to look at Njiellalajävri lake and surroundings in the Käsivarsi wilderness area. This is a far-away area almost at the Norwegian border. We saw no one in the area except for a few reindeer. There are not even common hiking paths. The Internet knows very little about this lake, not even a picture. Despite the incredible beauty of the lakes and the rock! We knew the area only through satellite images, geological surveys and maps.

I had only heard about the Postojna Cave before coming to Slovenia. But it turns out that there are many caves (of course) as well as many very interesting or famous cave sites. Right next to the Postojna cave, a 10 minute car ride away for instance is the Predjama Castle, which is world's largest castle built in a cave.

Took some dogs and kids to a cave today, the Högberget cave in Kirkkonummi (near Peuramaa). Amazingly, none of them were particularly impressed or interested. Just another place, moving on to picnics and computer gaming or peeing on plants and light poles... which is ok and natural.

We were driving back from the technical museum of Slovenia - a massive museum, by the way, well worth visiting. Then there was a hole in a cliff we drove by. I had to stop. The cliff was next to a parking lot and a bus stop, in town of Notranje Gorice near Ljubljana. No one was paying any attention... too many nice caves in this country, I guess. I decided to call the cave the Forgotten Cave. And I did go in.

Riding the train to the inside of the Postojna cave in Slovenia. The ride takes eight minutes through wonderful cave scenery. And then the actual cave tour starts, lasting an hour and a half. Is this the best show cave in the world???

Petnička pećina is an old but abandoned show cave in the limestone rock hills near the town Ваљево (Valjevo), Serbia. While only 600 meters long, the cave feels massive due to its vertical differences and the high halls. Just look the two people in the above picture for scale. And the "eyes" in the ceiling! The cave is also Europe's largest cave tomb.

Bärenhöhle: small cave by Central European standards, but a wonderful place to visit. And easy. A nice hike to a lush valley on a path and there you are. Water is flowing from the cave, dropping through the steps of rocks... moss has painted the cave green... there's a bit of climbing if you want to get to the end of the cave. Very nice!

The Finnish Caving Association had a nice meet-up in May ... we went to the Rokokallio, a high cliff in Vihti. High for Finland at least :-) Everybody joined... men, women, and dogs... and I worked with Ralf to systematically go through the cliff area and take positions and photos of all the caves. There's a total of 21 underground holes in the cliff and under boulders, though a few the holes are perhaps too small to be proper caves. We used Ralf's addition to the association's cave database user interface (Psgeo) to make the getting of the positions easy.
