Nice pic of tag. Still there in good condition in 2024.
This photo does not have GPS coordinates in the EXIF data as the camera was close inside the entrance and could not get a GPS fix. This is what we need photos of entrances from several distances, so that the more distant one does have a good GPS fix embedded in the photo.
The weird punching mistakes on this tag and the fact that the identifier "1623-148" does not appear exactly in that form is why we also need to record exactly the text that actually appears on the tag - to help resolve ambiguities in future. This happened for real for 2014-NP-01 (CUCC-745) which got confused with 2012-NP-14 because "2014" was written as just "14".
