Managed By: Icon Here Interested Geologists
A category in which to place interesting rock, sand, soil formations and deformations which have been created by natural (not human) forces.
Expanded Description:
Geology is the science and study of the solid matter of a celestial body (in this case the Earth), its composition, structure, physical properties, history and the processes that shape it. Waymarks in this category should exhibit one or more geologic processes (processes which either build up or tear down rocks/sand/or soil).

Most interesting rock formations are either a result of two geologic processes, erosion or volcanism but there are others such as meteorite craters, and earthquake related deformation to name just a few.

Instructions for Posting a Places of Geologic Significance Waymark:
(Requirements updated 10-May-2012 to require an explanation of geologic significance in the description. Existing waymarks are grandfathered.)

The waymarks in this category should be examples of interesting rock, sand, or soil formations. An explanation of the geologic significance of the location must be included in the description. Including information on the geological dating and/or minerology of associated rocks will help greatly to insure that your waymark gets approved.

Geologically interesting features which are already covered under another category will be denied. These include Caves, Glaciers, Mountain Summits, Natural Arches, active volcanoes, Rock and Mineral Displays and Paleontology and Fossils. As other more specific geologic categories are created they will become off-limits for this category, existing waymarks notwithstanding.

In the interest of environmental and civic responsibility, the following is a guideline.

Waymarks on public land which is already opened to the public and managed for visits to the location of waymark do not need approval from the land's management. Waymarks on public land which is unimproved for visitors, but otherwise open to unrestricted access by the public are also accepted. Waymarks on private land will be accepted if access is open to the public and this access is documented via a web site. Waymarks on private or otherwise restricted land will be accepted as long as the place of interest can be viewed from unrestricted public land (for example, road right of way).

If the category managers have any doubt as to the right of public access to the waymark, it will be deleted. Using web site references to build your case is encouraged.

Also, collecting and removal of any kind of sample from the site is strenuously discouraged.

A photo of the formation taken by the waymarker must be uploaded and used as the waymark page photo.
