It is located in the Parque de la Sierra y Cañones de Guara, a few meters from the river Alcanadre and close to the "fountain de la Tamara", is also near the pine forest of Morrano where pine are that are the most southerly of all the natural park and the Alto Aragon too.

[1] The inhabitants of Morrano have always called the formation "Peña Falconera" because according to tradition in this area falcons were bred, and "falcon" is the word's translation into the Aragonese language.

Today the nickname "Falconero" is still used by the inhabitants of Morrano.

A few years ago the stone was given a new name with the creation of the natural park.
