Earth Surface Processes and Landforms, Volume 51, Issue 3, March 2026.Eighteen boreholes in Colombia's Tropical Andes reveal elevation‐controlled Critical Zone architecture. Four‐layer weathering profiles with thick saprolite (≤48 m) form at high elevations (>1,100 m) where dense fracturing enhances permeability. Low‐elevation boreholes lack saprolite despite high fracture density, demonstrating fracturing's dual role as
