Yeah, ice is a big problem in that region. I remember it was common and was
frequently from the suface to well above my ceiling, anyway. In the midwest
it always seemed more stratified, so it was always possible to be somewhere
the ice wasn't. Not so in the hills. I think it was probably Altoona I'm
thinking of with the approach. A southerly runway, anyway.. I don't thnk I
was ever grounded by the weather, which seems remarkable to me now.

That is amazing! You must have been full deice, G1000, turbine -- the
works.

This winter has been non-stop ice -- warm enough and wet enough to
keep it constantly above and throughout the altitudes we fly. The
uplift created by the ridges wreaks more havoc than we realize.

The airliners are far above so there's no compelling interest to study
the phenomenon, but it is definitely unique.
