How to Mark a Foraging Spot and Find It Again

Record a foraging spot in three layers: a GPS pin dropped while you are standing on it, a written description of how you approached it, and photographs of the route and the surroundings. The pin gets you near; the words and pictures get you to the exact ground, which is where most people lose a patch.

Why the pin alone loses spots

A dropped pin feels like enough at the time. Then you come back eleven months later, the understory has grown in, the light is different, and your phone puts you in a circle of forest that all looks the same. Two things are working against you: the pin has real error, and the place has changed.

Every experienced forager has stood inside their own accuracy radius, unable to find the log they marked. The fix is not a better pin. It is a pin plus context that a human can navigate with.

How accurate a phone pin typically is

Under open sky a modern phone usually gets you within a few metres. Under a closed canopy, on a steep slope, or in a narrow valley it can be considerably worse, because the sky view is restricted and signals bounce. Treat these as rough expectations rather than guarantees; conditions and hardware vary.

Two practical consequences. Give the phone a few seconds to settle before you save, and if the spot really matters, drop the pin from the exact place rather than from the trail on the way past.

Write the approach, not the location

Coordinates describe a point. An approach description describes how a person gets there, which is what you actually need in the field. Write it in the order you will walk it.

• Where you parked or entered, and which way you set off.
• The decision points: forks, creek crossings, the gate, the third culvert.
• Roughly how far and how long between each one.
• The last leg off the trail: which side, how far in, uphill or down.
• The thing you will recognise when you arrive.

Keep it concrete. "Left at the split boulder, 60 paces up the old skid road, patch is on the north side of the third big fallen trunk" beats any amount of prose about the general area.

Landmarks that last, and ones that do not

Choose reference points on the timescale you care about. Anything seasonal or man-made can be gone by next year.

• Durable: rock outcrops, boulders, stream junctions, ridgelines, the shape of the slope, large living trees, standing dead trunks.
• Unreliable: flagging tape, cairns you built, fallen branches, puddles, undergrowth, colour of the foliage, anything a trail crew might tidy.

Note the aspect and the slope as well: north-facing at mid-slope tells you far more when you are relocating a patch than a bare bearing does. And a photo taken from where you stopped, looking toward the spot, is worth several sentences.

Assume you will have no signal

Good foraging ground and good cell coverage rarely coincide. Anything that has to load a map tile or reach a server is a plan that fails at the trailhead. Keep the spot record usable offline: the pin itself, the written approach, and the photos should all be readable in airplane mode, and you should carry a paper map and compass for anywhere you would be uncomfortable navigating without a phone.

Keep your spots yours

Patches are shared far more often by accident than on purpose. Photos carry location metadata, social posts get geotagged, and a screenshot of a map is a map. If a spot matters to you, keep the record somewhere that does not sync it anywhere, strip location data before sharing any picture, and be careful how much of the background is recognisable in the shots you post.
