Definition

As soon as you collect an item, put it in the correct bag or container and attach a label before you collect the next thing. Bag-and-Tag Routine is keeping each specimen tied to a location, a date, and a method so it doesn’t turn into a “mystery piece” later. Use a simple numbering scheme and write it on the bag, the field notes, and any photo divider you take. If a piece is fragile, label the container, not the specimen surface.

Collectors Context

Bag-and-tag routine is the difference between collecting and just picking up rocks. Decide your minimum label set before you start: site name, date, micro-location, and a short note on where it came from (bar, bank, pocket, layer). Keep labels waterproof and keep bags segregated so numbers don’t get reused accidentally. If you are collecting multiple targets, use separate bag colors or separate compartments so mixing cannot happen by accident. At the end of the day, do a quick cross-check: bag number matches notes and matches the photo sequence. Keep notes as you go—exact spot, surface type, and what changed—so you can repeat the same check on a future trip and compare results honestly.

Common Confusions

Bag-and-Tag Routine vs. Two-bucket sorting pass Bag-and-tag happens at the moment of collection; sorting passes are what you do later to separate keepers from maybes.

Bag-and-Tag Routine vs. Photo-first finds workflow Photo-first captures context before pickup; bag-and-tag preserves that context after pickup.

Bag-and-Tag Routine vs. End-of-site cleanout Cleanout is packing up; bag-and-tag is the process that prevents mixed, unlabeled material in your pack.
