Formation and Age of the Canyon

The Sumidero Canyon was formed during the geological processes that shaped the Sierra Madre de Chiapas mountain range. The canyon itself is approximately 8 million years old, a relatively young geological feature in the grand scheme of Earth's history. Its formation is primarily attributed to erosion caused by the Grijalva River, which has carved out the canyon through a combination of fluvial processes and tectonic activity.

The process began when the region experienced significant tectonic uplift, causing the land to rise and creating the highlands surrounding the canyon. As the Grijalva River began to flow through the area, it started to erode the softer sedimentary rocks, gradually deepening and widening the canyon over millions of years. The limestone, which is predominant in the canyon walls, is particularly susceptible to erosion, allowing the river to create steep cliffs that rise dramatically from the riverbanks.

Over time, the combination of water erosion, chemical weathering, and mechanical processes has led to the formation of steep walls that reach heights of up to 1,000 meters (3,280 feet). The erosion process continues to this day, as the river continually shapes the landscape, creating new geological features while erasing others. This ongoing geological activity contributes to the dynamic nature of the canyon, making it a living laboratory for geologists and ecologists alike.
