Determining whether you have found the correct disk marker


If are looking for a disk and have found one:

First look at the ["datasheet"] and read the [:designation:Designation] field. For example, the designation shown on the datasheet is: CREEK.

  • If you found a disk that says: CREEK then you have found the correct disk, even if it has a date with it, like CREEK 1959.
  • If you found a disk that says: CREEK [:reset:RESET] then you have not found the correct disk.

  • If you found a disk that says: CREEK [:reference mark:RM]1 then you have not found the correct disk. Refer to [:ReferenceMain:this] section to help you find the correct disk

  • If you found a disk that says: CREEK [:azimuth mark:AZ ]then you have not found the correct disk. Refer to [:ReferenceMain:this] section to help you find the correct disk

  • If you found a disk that has some other writing but not CREEK, then you have not found the correct disk whether or not it is in exactly the right place.

  • If the agency does not match, you probably did not find the disk. C&GS station CREEK is not USGS station BIG CREEK even if nearby.


If you were looking for a disk and did not find any:

  • Your looking and not finding does not mean that the station is destroyed. Never report Destroyed on that basis alone.
  • The NGS stance on the destroyed category is very conservative and they require proof of its destruction. A marker buried under 27 feet of re-landscaped dirt is not to be considered destroyed unless the NGS says it is destroyed. For geocaching logs, it is best to follow the NGS stance.
  • If the datasheet says the disk is mounted on a building and the building no longer exists then for a geocaching log, destroyed is probably the best choice. For an NGS recovery report, follow their instructions in the NGS [http://www.ngs.noaa.gov/FORMS_PROCESSING-cgi-bin/recvy_entry_www.prl Mark Recovery Entry] page's note 1.

  • If the disk is mounted in a bridge ["abutment"], tower footing, or other such item that appears to be gone/replaced, note that the disk may still exist in the now-buried remains of the structure in the proper place, and therefore is not destroyed.


If you looked for a disk and found the correct disk dug up and moved out of its proper position.

  • Report Destroyed on a Geocaching log or, in the case of the NGS, follow the instructions given in the NGS [http://www.ngs.noaa.gov/FORMS_PROCESSING-cgi-bin/recvy_entry_www.prl Mark Recovery Entry] page's note 1.

  • If it is not really removed all the way out of its position, but just moved slightly or tipped to one side, report: Found condition Poor.
