Quick Summary
The term "antecedence" refers to something that goes before in time or has priority. In geology, antecedent drainage describes river systems that existed before significant geological uplift occurred. These rivers maintained their courses, carving canyons through rising landforms like mountains or upwarps, rather than flowing around them. This phenomenon is a result of rivers eroding through the land as it is being uplifted, demonstrating a remarkable persistence of drainage patterns over geological time.1234
