Holes in the bedrock made by grinding stones in running water under the cover of ice during the last ice age. These holes can be several meters deep and wide. We call them "jettegryter" = "giants pans". Do you have a word for such holes in English?
Here a bullrush finds enough water even in dry spells in summer.
Interesting travels Trond, some of the rock formations are most scenic. Not small holes, but larger ones caused by glaciation, are called "kettle ponds" or "kettle holes", see
http://en.wikipedia.org/wiki/Kettle_%28landform%29
I was going to joke that we get these large holes in the road every winter in spring,
pot holes
, but I guess these kettle holes can be called potholes too, based on the wikipedia link.

Kettle holes are a little different again... not caused by erosion by rocks and flowing water, but rather, by subsequent melting of a block of ice that became encased in glacial sediments as the glaciers melted back.

I think Lori is right, Mark, kettleholes is called "kjelehull" (same word) or "dødisgrop (= dead ice pit) in Norwegian. It is a different kind of formation.
It is a fine area for coastal hike but you have to use a boat!

Just like I have said to Todd, about liking and learning about wild New Foundland by his photos, yours are equally interesting, Trond. All of them!!!
We have a few rock formations in Minnesota that have shallow, ephemeral pools that support fairly rare, and often endangered species of plants and amphibians. Our native
Phemeranthus parviflorum(Talinum parviflorum) & Phemeranthus rugospermus(T. rugosum)
are among them, although not considered rare. Your pools do seem a lot deeper than ours, and ours are not formed by what almost looks like cracks in the rock in your photos. rather, they are shallow depressions on the rock surfaces.
We call those holes "pothole", geologically speaking. Minnesota boasts the deepest (60ft. x 12-15ft.) and most concentrated number of them in the world. They are in Interstate State Park, only about 100 miles away from me. It's really a cool place to visit, and not just for the potholes.

Thank you, Rick, it's apleasure to show you (albeit timeconsuming with a cellphone!).
Your link is very interesting! I think pothole is the same as Norwegian "jettegryte". The biggest in Norway is 100m deep and 40m wide. The place is called Hell (Helvete)

100m x 40m, Wow!!! From the description given, your Norwegian potholes are formed the same way ours are. I guess our DNR (Department of Natural Resources) has not done its homework. Minnesota certainly doesn't have the deepest potholes in the world!

Wonderful photos, Hoy! #23 especially is gorgeous, perfectly framed, and feels so...still.
In eastern US we call the glacial phenomena "pot-holes". I like "giants' pans" better!

Thanks, Jeremy. I can tell you that it is more often than not
still
, you have the open ocean straight ahead! But I understand what you mean.
Here are a few more - it is thousands of similar and different motifs there.

The seaside views are just like Newfoundland....many of the plants are the same as well!...however, some of the plants, like Lotus and Lythrum, are considered invasive weeds on this side of the pond!
I don't recall any kettle holes in our area. Very unique.
I can see how the Vikings probably felt at home here when they arrived at L'Anse-aux-Meadows around 1000 years ago.

Great to see this area, and some lovely plants..the Lotus is also an invader here, not too common in my area--maybe in towns: I sometimes see some yellow things as I pass by in the car, though its not the only choice... I did see one plant in the foothills this summer, I wonder if it will be a whole hillside of them in a few years?
I'm very fond of P anserina-- originally I wasn't sure if it was native or introduced, but I have read its native, so I'd like to get some pieces, there are parts of my 'lawn' that could use it! Much nicer than grass
I saw some in a nearby town this year, so I will have to try to get some pieces....
