Sea Natural Arch
(Genetic type)
Examples: Great
Western Gateway, Sea
Lion Rock, Island Arch , unnamed arch
This type of natural arch is the result of wave
action on a coastal exposure of rock. Sea natural arches tend to
be short lived. However, new ones are constantly forming so they are
also rather common. The defining attribute for this type of natural
arch is the contextual attribute of being coastal. The coast may be
on any large body of water such as a lake, sea, or ocean. Because of
the random nature of wave action, sea natural arches exhibit a wide
variety of shapes and morphologic attributes. A maturity attribute cannot
be assigned to this type of natural arch.
