The Winking Man Rock formation (also known as the Winking Eye [5]) is part of the Ramshaw Rocks section of The Roaches. It looks like a face sticking out of the hillside, and as you travel past in a car towards Buxton the 'eye' appears to wink, as a pinnacle of rock passes behind the face as a consequence of parallax.

The prehistoric rock engravings of the Fontainebleau Forest are an abundant collection of rock art discovered among the sandstone boulders of the Fontainebleau Forest. Several thousand petroglyphs have been discovered in the forest, with earliest dating to the Paleolithic (very few examples), roughly 2000 to the early Mesolithic and almost 300 ...
Kummakivi in September 2015. Another angle with person for scale. Kummakivi (lit. ' odd stone ' or ' strange stone ') [1] is a large balancing rock in Ruokolahti, Finland.The 7-metre (23 ft) long boulder lies on a convex bedrock surface with a very small footprint but so firmly that it cannot be rocked with human force.
A rock formation is an isolated, scenic, or spectacular surface rock outcrop. Rock formations are usually the result of weathering and erosion sculpting the existing rock. The term rock formation can also refer to specific sedimentary strata or other rock unit in stratigraphic and petrologic studies.
Most rocks contain silicate minerals, compounds that include silica tetrahedra in their crystal lattice, and account for about one-third of all known mineral species and about 95% of the earth's crust. [6] The proportion of silica in rocks and minerals is a major factor in determining their names and properties. [7]
Sailing stones (also called sliding rocks, walking rocks, rolling stones, and moving rocks) are part of the geological phenomenon in which rocks move and inscribe long tracks along a smooth valley floor without animal intervention. The movement of the rocks occurs when large, thin sheets of ice floating on an ephemeral winter pond move and ...
Magma can be found in the mantle or molten crust. Magma (from Ancient Greek μάγμα (mágma) 'thick unguent') [1] is the molten or semi-molten natural material from which all igneous rocks are formed. [2]
It is an igneous rock. [6] Produced from felsic lava, obsidian is rich in the lighter elements such as silicon, oxygen, aluminium, sodium, and potassium. It is commonly found within the margins of rhyolitic lava flows known as obsidian flows. These flows have a high content of silica, giving them a high viscosity.
