Geographical trivia

The first, second, and fourth highest mountains in North America are in Alaska and the Yukon.

So where are the third and fifth highest?  (Not hard to search for, but this surprised me.)

Here's a nice picture of the third highest:

Pico de Orizaba/Citlaltepetl, Mexico.  Popocatepetl, also in Mexico, is the fifth-highest.
