Re: Maximum height of very cold ice mountain ?

You are right George:

Original size depends on material strength, but
Final repose, after mountain has yielded to gravity, slope self adjusts.
Cold, therefore brittle, and not plastic flow as in glacier ice.

What is repose angle for very cold ice ?

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?
