How should I search a field for meteorites?
Get permission, walk slowly in straight lines a few metres apart, scan for dark or out-of-place stones, use a magnet stick, and record anything promising.
Searching a field methodically gives the best chance of success and keeps you on good terms with landowners.
Permission first. Always ask the landowner or farmer before entering private land. Explain what you are doing, agree when you can search, and respect crops, gates and livestock. Promise to share any finds and discuss ownership in advance.
Plan. If you are searching for a recent fall, study any fireball reports and predicted fall areas. Divide the field into strips using landmarks or flags, or use a phone mapping app to record your track.
Walk in lines. Searchers often walk in parallel lines a few metres apart, scanning the ground ahead and to each side. Walk slowly and look down. Groups can sweep a field efficiently by keeping in line.
What to look for. Dark stones that look out of place, have a crust, are rounded rather than angular, or feel heavy. In ploughed fields, look on the sides of furrows. In grass, focus on bare patches and molehills.
Tools. A walking stick with a strong magnet attached to the end, sometimes called a magnet cane, lets you test stones without bending down. Some searchers use metal detectors, especially for iron meteorites.
Record finds. If you find something promising, photograph it in place, note GPS coordinates and pick it up with clean foil or a bag.
Safety. Wear suitable footwear and clothing, take water, keep away from machinery and livestock, and tell someone where you are.
