1. The most important aspect of what kind of log or recovery report to make is determining whether or not what you did find is the correct mark.

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 are looking for a water tower and have found one in the right place:

Read the datasheet carefully to note the description of the water tower, and the first date the water tower was reported or established as a survey mark. For example, the datasheet says the water tower has 4 legs, has a cone shaped top, and was monumented in 1931.

If you are looking for a non-disk item such as a bolt in a drill hole:

Be sure to read the entire datasheet carefully. Sometimes an older type of mark will be replaced by a disk but the datasheet will still indicate the older type of mark in the Marker Type or MARKER field. If the type of mark has officially changed, the change will be noted in one of the recovery reports, and the new type described in that recovery report. If there is no change in the type of mark indicated in any of the recovery reports, you must not assume a change in the type of mark and it will be as indicated in the Marker Type or MARKER field of the datasheet.

If you are looking for a church steeple, smokestack, radio tower, building cupola, or other such object and have found one in the right place:

Be sure to read the entire datasheet carefully. Pay particular attention to the date that the first date the structure was reported or established as a survey mark. The structure you find must be one that you're certain existed and appeared the same way as it did on that date. If the structure was re-built then the station is effectively destroyed since the re-built version of the structure might be an inch or so different in position. If you're uncertain about what happened during the time between when the structure was first monumented and the present time, check with the structure's building manager.

2. If you have looked and have found nothing.

Make sure whether or not the datasheet says the mark you're looking for has a location that is ["scaled"] or ["adjusted"]. If the location is scaled, you must use the landmarks and their distances and azimuths in relation to the mark as described in the datasheet instead of looking exactly where your GPS receiver indicates.

If you were looking for a disk:

  • 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 desctuction. 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 [http://www.holoscenes.com/cgi-bin/moin.cgi/abutment 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 were looking for an intersection station, such as a radio tower, building cupola, church steeple, water tower, etc.:

  • Take a photograph, prefereably with your GPS receiver showing the location. Try to take the photograph so that it demonstrates that you are in the right place looking for the intersection station. A good example is to photograph the remains of its foundation if they still exist.
  • 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.
