Question

9) Give two factors that might contribute to the persistence of this small glacier here, while most glaciers in the area at this elevation seem to be retreating or disappearing. (Hint: think about effects of direct sun on ablation, and avalanches on accumulaion (2 pts) 10) Castleguard Mountain lies-5 km to the west of Terrace Mountain. There are two beautiful but now abandoned terminal moraines on the SE side of Castleguard (look a few km SE from the marked summit). Both are cut by streams carrying meltwater. Once you have identified these old terminal moraines, estimate how far each of the two glaciers (actually small unnamed lobes of the ice field) has retreated since forming its terminal moraine. (2 pts)

Explanation / Answer

9 1 due to the presence of tiny rocky materials 2 due to the presence of some vegetation 3 sometimes due to the presence of persistent katabatic winds.

10 1 The distance between the glaciers will depend upon the rate of melting of ice of glaciers which carry moraines and the streams that carry melt water.

if the rate of melting and flow of water is more then the distance between the two glaciers is more and similarly viceversa.
