The Case for Writing It Down

Every collector ends up with a drawer of mystery pieces: a decent bit of quartz, a promising dark crystal, a chip of something green — and no idea where any of it came from. Six months after a trip you will remember the walk, the weather and the sandwiches, but not whether that cluster came from the spoil heap or the outcrop fifty metres uphill. A small notebook, kept in the same pocket as your hand lens, fixes this permanently. It costs almost nothing and it turns a scattered collection into a genuinely useful personal catalogue.

The aim is not scientific perfection. It is to record enough that your future self — or someone you pass the collection on to — can understand what you found, where it sat in the landscape, and why it looked the way it did.

What Every Entry Needs

Start with the essentials, written before you leave the site. Memory is generous on the day and unreliable by the following week.

• Date and time — the full date, plus roughly how long you were there. Season matters when you compare later finds from the same spot.
• Location — a grid reference from a paper map, a phone app or a GPS unit, plus a plain description such as "north side of the quarry, below the second bench". Grid references are precise; descriptions are how you actually navigate back.
• Access and permission — who owns the land, whether you had permission, and any restrictions. Many sites in the UK, particularly SSSIs and National Nature Reserves, prohibit collecting altogether, so note that you recorded and photographed but did not remove material.
• Conditions — recent rainfall, tide state on a beach, whether the ground was frozen, freshly plough, or recently disturbed by machinery. Exposure is often what reveals a find.
• Method — digging, sieving, splitting, or simply picking up a loose piece from a stream bed.

Write in pencil rather than ink. Damp hands and Welsh drizzle will do for a biro in a single afternoon, and a waterproof notebook with a waxed cover is worth the small extra cost.

Describing the Ground You Found It In

The surrounding rock tells you more about a specimen than the specimen alone. Note the host rock type as best you can — granite, slate, limestone, sandstone, basalt — and be honest when you are unsure. "Grey fine-grained rock, possibly slate" is far more useful than a confident wrong answer.

Then record the immediate setting:

• Position — in situ in the rock, embedded in a boulder, loose on scree, in a stream bed, or in mine spoil.
• Matrix — what the crystal is attached to, even if you break it off. A specimen with matrix carries context that a loose crystal loses.
• Associated minerals — anything sitting alongside it, such as iron staining, mica, calcite or pyrite. Associations are the single best clue to what a site produces.
• Size and quantity — dimensions of the largest piece found, and how common the material was. "One small cluster in twenty minutes" is a useful observation.
• Quality notes — terminations present, clarity, colour in daylight, obvious damage.

A Shorthand That Stays Readable

Field notes are written standing up, often in wind, so a simple personal shorthand saves time. The trick is to keep a key. Write your abbreviations on the inside cover and add to it as you go, otherwise you will invent a code that baffles you in a year.

Number every significant find with a consistent system: perhaps a two-letter site code, the year, and a running number, such as CW-26-014. Put the same number on the bag, the label inside it and the notebook entry. Small, neat handwriting and one find per line beats a dense paragraph every time. If you photograph a specimen in the field, note the image number beside the entry so the two stay linked.

Photographs, Bags and Labels

Photograph the find before you move it. A shot in situ with a coin, lens cap or ruler for scale takes seconds and preserves information that extraction destroys. Follow it with a close, well-lit image of the specimen itself.

Wrap material individually in newspaper or acid-free tissue, then place it in a labelled bag with a paper label written in pencil — pencil survives damp and does not bleed. Never rely on writing on the outside of a bag alone; bags get swapped, torn and faded. Keep the notebook and the sample numbers synchronised before you leave the site, not when you get home and the details have blurred.

Turning Notes into a Working Catalogue

At home, transfer the day's entries into a single catalogue: a spreadsheet, an index-card box, or a bound ledger all work well. Keep one line per specimen with its number, species or best identification, site, date, and a short note on matrix and associations. Back it up. Add photographs later, filed under the same number.

Review the catalogue once a year. Patterns emerge that were invisible in the field — a particular band of rock that keeps producing, a beach that yields best after winter storms, a site where you have never found anything worth keeping. That is the real value of good field notes: not the record of what you found, but the quiet instruction on where to look next.
