Late Pleistocene glacial equilibrium-line altitudes in the Colorado Front Range: a comparison of methods

Auteur :
MEIERDING, T. C.

Description :
Six methods for approximating late Pleistocene (Pinedale) equilibrium-line altitude (ELAs) are compared for rapidity of data collection and error (RMSE) from first-order trend surfaces, using the Colorado Front Range. Second-order trend surfaces demonstrate low ELAs in the latitudinal center of the Front Range, perhaps due to higher winter accumulation there. The mountains do not presently reach the ELA for large glaciers, and small Front Range cirque glaciers are not comparable to small glaciers existing during Pinedale time. Therefore, Pleinstocene ELA depression and consequent temperature depression cannot reliably be ascertained from the calculated ELA surfaces.
