Benchmark – The definition is rather fuzzy and can have several meanings.  In this blog, it will be used in two ways:  1.  A general reference to all objects listed in either the National Geodetic Survey (NGS) database or the benchmark listings at http://www.geocaching.com.  This includes survey disks, PK nails, chiseled squares, chiseled crosses, steeples, cupolas, flagstaffs, and many other objects that have been used either for precise surveying or by intersection surveying (reckoning by eye).  2.  A specific class of survey disks, usually with a triangle embossed on it and/or with the word “Benchmark.”

Geocache – a container that has a log, with or without a pen/pencil, and usually contains ‘treasure’, which are trinkets usually worth less than $5.

Polaris – 1.  The star that is situated above earth’s rotational axis and has the nickname ‘The Pole Star’ and marks true north in the night sky.  2. As referenced in the blog otherwise, it is to refer to a companion in my travels.  This could be a friend, a family member, a coworker, my girlfriend/fiance, or even a complete stranger [though I have not used it that way, yet and can’t think of an instance where I would].  This way provides some privacy for those along my way.

Waymark – This term has at least two meanings.  1.  A location entered into a GPSr that either marks an item of interest to find or marks the present location where you were when you made it.  IN THIS BLOG, I WILL TRY TO USE WAYPOINT, INSTEAD.   2.  A location that has been posted on the web site:  http://www.waymarking.com.

Waypoint – A location entered into a GPSr that either marks an item of interest to find or marks the present location where you were when you made it.
