[Mt Rainier being dominant]

Jane:
>>And that dominates things, yes. But then it has no competition.

As Jane goes on to say, neither does Kero Fin. IIRC its 4-5x taller than any other mountains in the region and, of course, *much* pointier than any mountain could be on earth (BTW if KF was on earth, then if you were on the peak the horizon would be a smidgeon under 260 miles away).

Hmmmm... unlimbering my schoolboy trigonometry and assuming that KF's peak is a bit over 10 km higher than a 'typical' sartarite field or what have you, then at 100km distance it'd stick up, ummm... tan = 0.1046, invert it... 5.97 degrees from the horizon. The moon is about 2 degrees in diameter so stack three moon widths onto a convenient horizon in your minds eye to give you an idea of how KF would look from ~60 miles away on a clear day.

If you assume that a significant other peak is about 1km taller than this typical sartarite field (ie. 6000' vs 3000') then it'd need to be within 6 miles before it blocked your view of KF.
