Will a bunker eventually turn into a cave?

I wonder what happens to human-made underground structures, when enough time passes by? Will they turn into caves. or cave-like environments, eventually?

We had an opportunity to explore a Soviet-occupation era bunker in Solbacka, Kirkkonummi on Sunday. This bunker was abandoned (and destroyed) 62 years ago.

In 2018, we found plenty of long, thin straw stalactites dropping from the roof. And a number of thick, beautiful stalagmites growing from the rocks upwards.

Interestingly, some of the stalagmites appeared as if they had been cut at some point in time. A visitor breaking things years or decades ago?

We stopped our exploration and exited the bunker, however, when we realised that there was also a bat hibernating in the tunnel deep inside the bunker.

Cave forms, bats? Quite interesting.

I wonder what a large underground parking garage would look like after 100 or 500 years of neglect... probably very much like a cave.

On the trip we had Velma, Heli, Tor and myself. An idea for this Kirkkonummi exploration came from sitting at aFinnish Caving Association's bar evening on Thursday.

Kirkkonummi is near, and has many interesting exploration destinations, ranging from small to large (by Finnish standards) caves, and hundreds of bunkers and other structures left by the Soviet occupation of Porkkala after the 2nd world war.

Coordinates: N 60.145421 E 24.431264.

Here are some cave forms:

The North Face Unveils ‘PERSPECTIVES’, A Film Series Exploring Change

Change is a constant of life. We can’t control change, but we have autonomy over how we react to it. For folks who thrive in the outdoors, this rings especially true. We’re constantly at the mercy of Mother Nature, coping with changing elements, seasons, conditions, or goals. For someone like filmmaker Renan Ozturk, his life was always dictated by climbing. It was his compass, guiding him from one grand adventure to the next. But Ozturk wouldn’t be the filmmaker he is today had he never

Viridiana Álvarez Is Breaking Barriers in the Mountaineering World

Simply summiting Everest, K2, or Kangchenjunga is a remarkable accomplishment in its own right. Last year, Viridiana Álvarez did all three in one year and 364 days, making her the fastest woman ever to do so. And while the world record is a nice reward, the mountaineer from Mexico simply hopes that her adventures will inspire other Latinx women to dream big and carve their path in the outdoors. Her next big goal is to climb the 14 biggest mountains globally, and she’s already crossed five off
