1. River channels, V-shaped valleys , and mixed Dipterocarp rainforest also characterize the forest reserve. 2. It is an oval-shaped valley long with an average width of. 3. Numerical models have been created to explain the phenomenon of carving U-shaped valleys . 4. The U-shaped valley is deep and was formed during the last glacial period. 5. Meanwhile, V-shaped valleys are noted to have been composed and dominated by sandstone. 6. Upper Wensleydale is high, open and remote U shaped valley overlying Yoredale Beds. 7. During Holocene sea-level rise, fjord estuaries formed by drowning of glacially-eroded U-shaped valleys . 8. Adjacent V-shaped valley formations give the remaining fault spurs a very triangular shape. 9. It is a V-shaped valley and has been predominantly shaped by the Partnach river. 10. Glaciation took place around the volcano roughly 6700 years BP, carving out U-shaped valleys .
