a) Mælingar á jökulsporði South Cascade Glacier.
b) Breytingar á afkomu. Skyggðar súlur tákna mælda afkomu. Oskyggðar súlur tákna reiknaða
afkomu út frá einstökum mælingum á gangi jökulsporða.
c) Breytingar á afkomu. Deplar sýna 10 ára meðalgildi reiknuð úr frá jökulsporðamælingum.
Hringur táknar mælt meðalgildi 9 ára.

a) Record of terminus position of South Cascade Glacier. • observed positions (Meier and
Tangborn, 1965), o interpolaled positions.
b) South Cascade Glacier. Time variation of net budget. Shaded step curve; observed, inferred
from data of Meier and Tatngborn (1965). Unshaded step curve: computed from unsmooth-
ed terminus record.
c) South Cascade Glacier. Time variation of net budget. Dots sliow 10 yr. running means of
values computed from terminus record; open circle, observed 9 yr. mean (Nye 1965).
