Mountains and Valleys in Texas, USA and Mexico29.7N 101.7W
This APM image shows hills and river valleys north and south of the border between Mexico (below) and Texas, USA (above). The topography in Mexico is significantly higher, with mountains reaching heights of over 1200 meters (almost 4000 feet), while in Texas, the hills are half that size, at around 600 meters (2000 feet).
To the north, in Texas, the Pecos River can be seen flowing through a valley near the right edge of the full image. The river arises near Pecos, New Mexico, United States, and flows for 926 miles (1,490 km) through the eastern portion of that state and neighboring Texas before it empties into the Rio Grande near Del Rio. The river’s drainage basin is approximately 44,300 square miles (115,000 km2) in size.
