This aerial view taken on March 12, 2026 shows Krzysztof Bieresniewicz, an amber hunter, together with his team searching for amber using the hydraulic pressure method in a field in Laszka, northern Poland. The method is based on using a pipe and a special rod to pump water at high pressure several metres underground, which causes pieces of amber to be washed up to the surface where it can be easly collected by pickers into collection nets. Formed some 40 million years ago from conifer resins, amber often contains air bubbles, plant fragments or insects trapped before fossilisation, granting each piece a unique "fingerprint".
