Halonen Cave

	Halonen Cave Halonen Cave is a cave in Säkkilä village, Halosenvaara, Kuusamo, Finland. The cave forms a passageway that expands into a room-like space, and in which the tilt of the floor grows towards the back of the cave. The cave is shaped like a cylinder A cylinder (from ) has traditionally been a three-dimensional solid, one of the most basic of curvilinear geometric shapes. In elementary geometry, it is considered a prism with a circle as its base. A cylinder may also be defined as an infin ..., and is almost round. It is over 15 meters long, and its height at the middle is approximately 3 meters, and received its name from one of its landowners. References {{Reflist Caves of Finland Kuusamo ...

picture info	Cave A cave or cavern is a natural void in the ground, specifically a space large enough for a human to enter. Caves often form by the weathering of rock and often extend deep underground. The word ''cave'' can refer to smaller openings such as sea caves, rock shelters, and grottos, that extend a relatively short distance into the rock and they are called ''exogene'' caves. Caves which extend further underground than the opening is wide are called ''endogene'' caves. Speleology is the science of exploration and study of all aspects of caves and the cave environment. Visiting or exploring caves for recreation may be called ''caving'', ''potholing'', or ''spelunking''. Formation types The formation and development of caves is known as ''speleogenesis''; it can occur over the course of millions of years. Caves can range widely in size, and are formed by various geological processes. These may involve a combination of chemical processes, erosion by water, tectonic forces, microorgani ...

Kuusamo Airport is located north-east from Kuusamo town centre. History Sami settlement Until the 17th century, the area of Kuusamo was inhabited by the semi-nomadic Sami. During the cold season they lived in the villages Maanselkä and Kitka. In spring they moved to the rivers and in summer, after the melting of the ice, to the lakes; there ...

picture info	Cylinder A cylinder (from ) has traditionally been a three-dimensional solid, one of the most basic of curvilinear geometric shapes. In elementary geometry, it is considered a prism with a circle as its base. A cylinder may also be defined as an infinite curvilinear surface in various modern branches of geometry and topology. The shift in the basic meaning—solid versus surface (as in ball and sphere)—has created some ambiguity with terminology. The two concepts may be distinguished by referring to solid cylinders and cylindrical surfaces. In the literature the unadorned term cylinder could refer to either of these or to an even more specialized object, the ''right circular cylinder''. Types The definitions and results in this section are taken from the 1913 text ''Plane and Solid Geometry'' by George Wentworth and David Eugene Smith . A ' is a surface consisting of all the points on all the lines which are parallel to a given line and which pass through a fixed plane curve in a p ...
