Surface Forms of Mineral Soils in the Yukon Territory
A long, narrow elevation of the surface, usually sharp crested with steep 166 sides. The ridges may be parallel, subparallel, or intersecting
A flat or very gently sloping, unidirectional surface with a generally constant slope not broken by marked elevations and depressions. Slopes are generally less than 2% (1°)
A regular sequence of gentle slopes that extends from rounded, sometimes confined concavities to broad rounded convexities producing a wavelike pattern of low local relief. Slope length is generally less than 0.8 km and the dominant gradient of slopes is 2-5% (1-3°)
Erosional slopes, greater than 70% (35°), on both consolidated and unconsolidated materials. The form of a steep erosional slope on unconsolidated materials is not related to the initial mode of origin of the underlying material. Rock and Ice.
A sloping, unidirectional surface with a generally constant slope not broken by marked irregularities. Slopes are 2-70% (1-35°). The form of inclined slopes is not related to the initial mode of origin of the underlying material.
