Melting of the ice left an unstable landscape where loose sand, gravel and rock were easily eroded and washed away. Saturated glacial sediments and rock slumped and slid downhill, sometimes where weak mudstone layers failed or where faults cut the rock. The steep slopes of Mallerstang Edge, east of the Westmorland Dales, display spectacular late- to post-glacial landslides, with scoop-shaped scars and debris piles below.
Cold climates continued intermittently after the ice had melted. Seasonal freeze-thaw processes caused gradual downhill movement of glacial deposits and soil, and also shattered bedrock, leading to accumulations of scree below crags. The northern slopes of Potts Valley and Hazzler Brow Scar on its east side display these features well.
