Aguas Zarcas is a witnessed CM2 Carbonaceous Chondrite fall from Alajuela Province, Costa Rica, which occurred on 23 April 2019. The fall was widely observed and quickly recovered, with stones found around the Aguas Zarcas area shortly after the event. It is regarded as one of the most significant CM2 Carbonaceous Chondrite falls since Murchison in 1969, providing unusually fresh material from a volatile-rich and organic-bearing parent body.
Specimens of Aguas Zarcas are typically dark, fine-grained, and fragile, consistent with CM2 material that has experienced aqueous alteration. Many pieces show a black fusion crust, while interiors can reveal a dark matrix with small pale speckles, hydrated minerals, and organic-rich components. Some fragments were recovered very soon after the fall, limiting terrestrial contamination and making the material especially valuable for scientific study.
For collectors, Aguas Zarcas offers a rare combination of witnessed fall provenance, Carbonaceous chemistry, and strong scientific importance. Its Costa Rican origin, rapid recovery, and connection to early solar system water and organics make it especially desirable for focused Carbonaceous Chondrite and witnessed fall collections. Each specimen represents primitive asteroid material delivered to Earth in one of the most important modern meteorite falls.
