Geographical Features:

Guadalupe County covers an area of approximately 3,032 square miles (7,856 square kilometers) and is bordered by several other counties, including De Baca County to the north, Lincoln County to the east, and Torrance County to the south. The county lies within the Great Plains region of the United States, with elevations ranging from around 3,500 feet (1,067 meters) in the plains to over 8,000 feet (2,438 meters) in the mountains.


The majority of Guadalupe County consists of rolling plains that stretch out across vast expanses of land. These plains are characterized by their flat to gently undulating terrain and sparse vegetation, mainly consisting of grasses and shrubs adapted to arid conditions. The plains support agriculture, ranching, and oil and gas extraction, which are significant contributors to the county’s economy.


In the western part of Guadalupe County lies the Sierra Grande, an extinct volcanic mountain range that rises dramatically from the surrounding plains. Sierra Grande is the largest shield volcano in the Raton-Clayton Volcanic Field and reaches an elevation of approximately 8,720 feet (2,658 meters) above sea level. The rugged terrain of the Sierra Grande provides habitat for a variety of wildlife and offers opportunities for outdoor recreation such as hiking and wildlife viewing.

Rivers and Waterways:

Guadalupe County is traversed by several rivers and waterways that play a vital role in shaping the landscape and supporting ecosystems. The Pecos River is the most significant watercourse in the county, flowing from its headwaters in the Sangre de Cristo Mountains to the east and passing through the county before joining the Rio Grande further downstream. The Pecos River provides water for irrigation, recreation, and wildlife habitat, with fishing and boating being popular activities along its course.

In addition to the Pecos River, Guadalupe County is also home to other waterways such as the Canadian River and the Llano Estacado, which contribute to the region’s hydrology and provide water for agriculture and livestock. These rivers and waterways are essential for maintaining the ecological balance and supporting biodiversity in the area.


Guadalupe County experiences a semi-arid climate characterized by hot summers, mild winters, and low precipitation levels. The region’s climate is influenced by its location in the southwestern United States and its proximity to the Great Plains.
