4.6. Planetary geology on Earth

The Planetary Geology on Earth series of EarthCaches was created to give geocachers the opportunity to view and learn about geological features on Earth that also exist on Mars, or other planets with documented geology. All EarthCaches in this series

• Must follow this naming convention Planetary Geology on Earth: __________.
• Must meet all of the standards and guidelines of EarthCaches for the geological feature on Earth. Information about the same feature on Mars or another planet is extra.

Additional points:

• You can create new EarthCaches to be part of the series, or modify an existing EarthCache by adding information and an image about a corresponding feature on Mars.
• You may need to travel to find an appropriate feature on Earth. Some parts of the Earth don't have any visible geology that matches a similar feature on Mars.
• The example on Mars should have a clear connection or resemblance to the feature used on Earth. It is not sufficient to say in your description only that the same thing exists on Mars — you need to show it.
  
• Uniqueness still applies. Example: If you like the layers of sedimentary rock on Mars and choose a location on Earth where there already is an EarthCache on the same topic, you will need to choose a different location or type of feature.
• There is a character limit on cache titles.  If you can't fit your cache name in after "Planetary Geology on Earth: " please shorten it to fit in the remaining space.
• Visit the Geological Society of America's page for Planetary Geology on Earth.
  
• The Geological Society of America has produced a list of resources that can be used for the planetary aspect of these EarthCaches: Planetary Geology Resources Compiled by the Geological Society of America (GSA).  Pro Tip: Be sure to remember EarthCache guideline #8 when using these.
