Vesicular basalt rock ? Spotted on one of Tjärnö island beaches (Bohuslän, Sweden). It's the only one around. Not clear how it got there. Partly covered with flashy orange lichen (Xanthoria parietina).

Stan, that is one wild place. I visited a couple of years ago and thought I would maybe do some camping there! It was so windy you could barely open the car door...
It is really like the moon.

But do they also exit?

It depends, without enough light those tubes can be hazardous. But, if I did it, anyone can do it, don't you think?

Wasn't windy during my visit, but I'll take your word for it. Just think how wild it was with all that lava flowing.

Yes, but did you do it?

Here's inside one of the tubes.

They advertised on a road near that hole with a sign pointing to the "Ice Caves." There was no ice. When we visited the Delaware Water Gap area, there was also a sign for an Ice Cave. No ice was located there either. We now use the term "ice cave" universally for something that isn't true to what is expected.

Idaho has cold winters. Maybe you were there during the season of thaw?

Along the road between Cameron AZ and the Grand Canyon east entrance. Imagine coming across this back in the days of the pioneers, and it's only a hint of what lies ahead as you travel west

The Briksdal Glacier, Norway.

 

[Nordlys]

Okstindbreen, not far from Mo-I-Rana in Northern Norway, on my third visit in the late nineties. Even then, after crossing the glacier lake you had to walk for a while to approach the ice edge. Like many others it has been receding considerably and I can't imagine how much of it is left today.

An old slide from that time:

Svartisen Glacier in the Norwegian Saltfjellet-Svartisen National Park has been going through similar shrinking phases and I hear that these are accelerating. I'm glad I could capture the magic of these environments then, even if that was with fairly primitive photographic means compared with what could be achieved today.

Two older slides that probably do not reflect its present look.

Almost looks like a painting. If only the sky had cooperated with a few clouds............
