Comparing the dominant factors contributing to stable snowpack in the two basins and across the two seasons, elevation emerges as a common factor influencing all types of stable snowpack. This suggests that the distribution pattern of stable snowpack is primarily driven by elevation. However, the dominant factors vary considerably between different regions and seasons within the same region.
