-
On average, balances driving stress i.e. over a few ice thicknesses

w/Csliding
-
If stresses do not balance, eqn overestimates velocities

V. Fast
Flow

-
Since:
- Only discrete regions exhibit fast flow & low basal stress
- Antarctica still exists (all ice would've been lost if whole AIS had no basal stress)
