The ceheginero Francisco Jesús García Hidalgo, amateur geologist and municipal archivist, is located in the municipality of Cehegín the mold of a tree fossil 'Pleistocene', in a tuffaceous formation not far from town.
The tree was covered with calcium carbonate in an area of springs which possibly can be framed in a interestadial chronologically within the Würm glaciation, which was a very mild climate and abundant water.
The tuffs are formed by precipitation of calcium carbonate groundwater when exposed to the surface, deposited on vegetation and building structures, sometimes many feet thick.
Tuffs in this area of abundant fossil leaves of deciduous trees and conifers are present in the middle levels.
It believes it has a probable age around 30,000 years, although it is possible that the sources who were there in moments of greater or lesser abundance of water, persist, at least until about 8,000 or 10,000 years.
Cehegín, in this period, he was a garden with many outcrops of spring water.
