A truncated spur is a mountain ridge, sloping down into a valley, that has had its lower end cut off by a glacier. In the most typical usage of this term, faceted spurs are formed by active faulting, especially normal faulting that produces well-defined triangular facets along either a mountain front or edges of a rift valley. Interglacials, on the other hand, are periods of warmer climate between glacial periods. It occurs when ridge spurs, which were formed in a mountainous area by river action, have been (or are still being) truncated by the action of ice or active faulting. m=30. Subscribe today!
