the Ferrocarril General Belgrano at Urundel in Salta Province. 
The vegetation at Urundel is the so-called Selva Chaquena, a dis- 
tinctive type of subtropical deciduous forest, which in northwest Ar- 
gentina north of Ledesma forms a relatively narrow band of transi- 
tion between the dry Chaco Scrub on the east and the much wetter 
Selva Tucumano-Boliviana on the west at the base of the mountains.
