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 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 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 ["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.
