Collectors keep
field labels simple enough to use every time. Use waterproof paper or a tag that won’t dissolve, and a pen that writes on damp surfaces. Make your label match your notes: if your notebook uses Run 3 at Waypoint 12, the bag should say the same. When you split material (keepers vs. tests), duplicate the label so both containers stay tied to the same run. At the end of the trip, reconcile labels with photos and notes and fix any outliers immediately—one corrected label now saves hours of confusion later.
Write labels while the find is in front of you. If you wait until the car, bags and pockets start mixing and the “best guess” becomes the label. Use a unique number or code that ties directly to a notebook line and a photo set.
