The Triglav Glacier and Skuta Glacier are the last remaining, although disappearing, surface ice masses in Slovenia. Based on environmental tracer profiles, the ice between 0–100 cm predates the 1960s at Triglav, suggesting negative net accumulation since the early 1960s. Ice below 1 m is older than 70 years. Skuta Glacier shows similar patterns, though deeper layers are affected by percolation water. Skuta Glacier shows relatively stable deposition (~5.5 cm/year) from the 1860s to 1960s, while Triglav Glacier had lower and declining rates (3.8 cm/year before 1900, dropping to 2.1 cm/year by the 1960s).
