Second my bad...what airspace in the US 18K and 60K is not
Class A?


There's no Class A airspace over Hawaii, the Alaska Peninsula west of
longitude 160° 00' 00" West, the California islands Santa Barbara and
Farallon, and the Florida keys south of latitude 25° 04' 00" North.



Not counting the big mountain in Washington state. (sorry, can't remember
the name)


I think you mean Alaska. The highest point in the contiguous states is
California's Mt. Whithey at 14,494 feet. The airspace above 18,000' but
less than 1,500 feet above the surface of the earth in Alaska is not Class
A.
