Sierra de Picachos and Falcon Lake, Texas, USA and Mexico26.6N 99.2W
This orthorectified wide-swath ASAR image shows the Sierra de Picachos, in the state of Nuevo Léon, Mexico, appearing as an oval area of mountains near the left edge. The mountains cover a surface area of 1405 km². It ranges from 400 to 1200 meters above sea level.
Visible northeast of the range, near the right edge, is the Falcon International Reservoir, commonly called Falcon Lake. It is a reservoir on the Rio Grande 40 miles (64 km) southeast of Laredo, Texas, USA, and Nuevo Laredo, Tamaulipas, Mexico. The huge lake is bounded by Starr and Zapata counties on the Texas side of the international border and the municipality and city of Nueva Ciudad Guerrero on the Tamaulipas side of the border. The reservoir was formed by the construction of the Falcon Dam to provide water conservation, irrigation, flood control, and hydroelectricity to the area.
