Two interesting agate-finding-localities are the neighboured areas of El Pajarito and Passo del Berwin east of the township of Esquel. In this areas collectors are able to find windpolished agate specimen between very similar looking rocks on the surface in a desert-like region. This highly reflecting surface given to the rocks by the sandblast of an everlasting desert wind looks almost like a man made polishing - but its all natural !

The nodules are showing a pattern of fine banded agate in a lot of pastel-tones like pinkish, reddish, yellowish and bluish. Intensively coloured specimens are very rare.
