Standing sentinel at the centre of the Memorial are six huge basalt obelisks, etched with the names of all the countries where Australians were held prisoner of war.
Basalt cliffs on the west side of Table Mountain, Okanogan-Wenatchee National Forest, Kittitas County, WA. About a month after this photo was taken, this forest was devastated by a lightning-caused forest fire.
Whoops, I knew the line was only regularly worked on a Saturday but I managed to choose a week before it finally reopened with a bridge out nearer to Hagen. A record for modelling.
Gerðuberg
Gerðuberg is a spectacular basalt cliff on the southern coast of the Snæfellsnes Peninsula in West Iceland. The cliff is famous for its remarkably symmetrical hexagonal basalt columns, formed when lava cooled and contracted thousands of years ago. Rising in orderly vertical formations, Gerðuberg is considered one of Iceland’s finest examples of columnar basalt and is a popular stop for photographers and geology enthusiasts.
Snæfellsnes Peninsula Often called "Iceland in Miniature," the Snæfellsnes Peninsula is one of the country's most diverse regions, featuring volcanoes, glaciers, lava fields, black-sand beaches, fishing villages, waterfalls, dramatic cliffs, and rugged coastlines. Dominating the peninsula is Snæfellsjökull, the glacier-capped volcano made famous by Jules Verne's novel Journey to the Center of the Earth. The peninsula is widely regarded as one of Iceland’s most scenic destinations due to the variety of landscapes concentrated in a relatively small area.
The volcanic basalt structures have given way to the eroding powers of the river, wearing out a steep canyon in the Icelandic rock formations

As the outer surface of a lava flow cools and hardens, it provides a rigid insulating structure that allows hotter lava to flow within it. These igneous conduits are called lava tubes and when the flow of lava is depleted, hollow cavernous spaces are left behind. Many of these empty spaces collapse, which produces a landscape that looks like a deflated souffle from the surface, though some remain intact as caves that can be traversed.
