In 1951 a farmer uncovered a meteorite in an unknown location near Esquel while digging a hole for a water tank. The meteorite was purchased from the finders and taken to the United States in 1992 by meteorite expert Robert Haag. The Esquel pallasite is known world-wide among collectors and the meteoritical scientific community. Esquel is one of the most beautiful meteorites ever found and is also one of the most desirable pallasites among meteorite collectors. It is a main group pallasite (MGP).
The Meteoritical Bulletin no. 29 (1964) reports a main mass of "about 1500 kg". However O. A. Turone claimed a main mass weight of 755 kilograms (1,664 lb). Robert Haag, the buyer of the main mass, reported a weight of 680 kilograms (1,500 lb). Almost all of the Esquel ever found on the market is cut from his piece.
