Model scale
6 × 4 km selected valley. relief ×1.5. ice flow remains down-valley.
Selected valley ice length 3.75 km. Play always moves ice down-valley.
Extent compares margin positions independently; it does not reverse flow or calculate a mass-balance response. Hide Ice to inspect the trough and debris.
