Re: Maximum height of very cold ice mountain ?

Varying slope:
A modification of the "scale height" exponential tapered column.

However, strength is a function of pressure.
Varying respect to height and distance from the axis of the column.

I am trying to figure out maximum height a given diameter base
can support, cooled to liquid nitrogen temperature.

Cannot find strain rate data for ice at very low temperatures and high
pressures, into the TPa range.

Can the 1 : 1 1/2 max stable slope of sand dunes be used ?

Resulting shape parabolic as in ice fields ?

Exponential taper as in scale height of a column ?

Would the angle of repose be appropriate in this situation?
