Alaska – Matanuska. Thoughts about the frontal moraine

June 8, 2015 in @en, focus-en by Sliger.M

The most recent frontal moraine pushed by the Matanuska glacier (Alaska, USA) appears as an unsorted till mound with relatively recent vegetal cover (Figure 1). Opposed to it, in the lowest areas of the ablation moraine, the till is generally reworked by the dynamic hydrological processes of the thawing glacier. This glacier and ablation moraine complex is still active, and is a good site to observe the contemporary land forms that became relict at the Beaver Creek study site (Yukon).
