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 rise of temperature, however, may be only a tiny increase; we know more than one instance of sedimentary deposits which have been buried beneath four or five miles of similar strata (e.g. parts of the Old Red Sandstone), and yet no perceptible difference is apparent between beds of similar composition at the top of the series and near its ...
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.
Increase in temperature is the most typical mechanism for formation of magma within continental crust. Such temperature increases can occur because of the upward intrusion of magma from the mantle. Temperatures can also exceed the solidus of a crustal rock in continental crust thickened by compression at a plate boundary. [76]
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]
Some Archean rock formations show macroscopic similarity to modern microbial structures, leading to the inference that these structures represent evidence of ancient life, namely stromatolites. However, others regard these patterns as being the result of natural material deposition or some other abiogenic mechanism.
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 ...
