forms

I have seen that kind of rock in France. It was called "orgues" (organ) Great photo

One more proof the nature is the best artist.

Australia is a land of geological contradictions with some of the oldest features in the world alongside rocks that are in the process of formation. The continent is home to rocks dating from more than 3000 million years while others are the result of volcanic activity which continued up to only a few thousand years ago. Towards the east, the flat land rises to the Great Divide which runs parallel to the east coast from the tip of the Cape York Peninsula in Queensland almost 4000km south to the Grampians in Victoria. This separates rivers flowing to the west and north from those flowing to the Pacific. The Eastern Highlands are made up of a series of mountains in the south topped by Mount Kosciuszko and volcanic plugs, ash domes and flow remnants further north. These are evident in areas such as the Mount Warning Shield Volcano formed about 23 million years ago on the New South Wales-Queensland border, the Glass House Mountains further north and Mount Surprise in North Queensland. These formations were created as Australia moved over a volcanic hotspot. Some southern plateaus are dissected by erosion into rugged hills with the eastern edge forming the high escarpments. Some of Australia's most spectacular waterfalls occur where rivers flow over the Great Escarpment. Source: www.ga.gov.au/scientific-topics/national-location-informa...

I was not able to find records for a Mountain Sand and Gravel in Pueblo but the vehicles in this series all have 1973 Colorado license plates.
