Long weekend in Shropshire based in Church Stretton.
The Stiperstones is a very distinctive hill in Shropshire. It is a quartzite ridge formed some 480 million years ago. During the last Ice Age the summit stood out above the glaciers and was subject to constant freezing and thawing which shattered the quartzite into a mass of jumbled scree surrounding several residual rocky tors. At 536 metres above sea level it is the second highest hill in the county, surpassed only by Brown Clee Hill.

Quartzite is the most unique flagstone because of the metalic finish it has. It is mostly silver with some gold tones and is smooth. Very durable.
Quartzite from the Precambrian of South Dakota, USA.
The bedrock in southeastern South Dakota includes outcrops of pinkish, Paleoproterozoic-aged quartzites. A famous locality is Falls Park along the Big Sioux River in the city of Sioux Falls, South Dakota. These rocks are part of the Sioux Quartzite, a 1.65 to 1.70 billion year old succession of metamorphosed sandstones. Despite the metamorphism, original sedimentary features such as horizontal stratification, cross-bedding, and ripple marks are still preserved.
The Sioux Quartzite is an erosion-resistant unit in America’s midcontinent. It has formed a long-lived paleotopographic high since Precambrian times - the Sioux tectonic core. This high is part of a northeast-to-southwest trending series of paleotopographic highs & depressions known as the Transcontinental Arch, which extends from Arizona to Minnesota (see Carlson, 1999).
Quarries of Sioux Quartzite occur in southeastern South Dakota and southwestern Minnesota. The rocks have been used as building stone, road gravel, sidewalk and paving gravel, and erosion control material.
Stratigraphy: Sioux Quartzite, upper Paleoproterozoic, 1.65-1.70 Ga
Locality: unrecorded / undisclosed site at or near the town of Dell Rapids (possibly from a quarry), southeastern South Dakota, USA

These massive quartzite sandstone statues which once guarded the entrance to the mortuary temple of Amenhotep III now stand virtually alone in a field at the side of the road to the Valley of the Kings. They weigh 1000 tons apiece and are 23 meters (75 feet) high.
Very hard, reddish purple Shinumo Quartzite near the "angular unconformity."
Abbott & Cook write: "You cross from the brown sandstones and thin, green mudstones belonging to the Tapeats onto extremely hard, reddish purple Shinumo Quartzite. With a single footfall, you step 550 million years back in time! This amazing gap in the rock record is marked by an angular unconformity..."
Taken between 6:30 - 7:45 am at Falls Park in Sioux Falls, SD.
I wasn't planning to do a shoot while visiting, so didn't have anything but my phone. It was such a beautiful morning, I couldn't resist.

This is quartzite conglomerate, a "plum pudding" stone, in which the quartzite "plums" are cemented in sandstone "pudding". The later represents an ancient sandy beach. The walls are zoned: layers of conglomerate alternate with bands where are relatively few pieces of quartzite. ( "Devil's Lake State Park Visitor", Wi DNR PUB-PR-111 2009).
