The mountain range of the divide is called the Cordillera de Talamanca near the Costa Rican border. Farther east it becomes the Serranía de Tabasará, and the portion of it closer to the lower saddle of the isthmus, where the Panama Canal is located, is often called the Sierra de Veraguas. As a whole, the range between Costa Rica and the canal is generally referred to by geographers as the Cordillera Central.
