Great work compiling this list! It is obvious that you have put a ton of work into in. One suggestion is to change Mexico's heading from "Central America." With the locations listed alphabetically, putting Mexico in with Central America is confusing, because Mexico is not part of Central America, it is part of North America.
Again, great work on an excellent list!
Glad you appreciate it. The reasoning behind the current structure is that the first section is done by geological location. Mexico's prolific volcanoes as I'm sure you know are a result of the Cocos plate subducting along its western margin, as is the case for the rest of Central America. This subduction region terminates at its north end with the Baja rift zone, and at its south end around the Costa Rica/Panama border. Mexico's northern volcanoes in Sonora etc are more part of the Basin and Range formation, but given that there is only one example of this on SP I lumped it in with the rest. I shall certainly put some more thought into how this page could be better organised, thanks for your suggestions.
Great point Baarb, that makes a lot of sense. I actually don't know that much regarding the geology of the volcanoes. Thanks for the brief lesson.
Have you looked into the Ortiz Mountains just east of the Sandia Crest in NM. They once formed an old volcano and are very similiar in nature to nearby Mt Taylor. The highest point in the Ortiz Mountains is Placer Moutain.
Hope this helps and thanks for putting together this great page.
Hadn´t yet, thanks for bringing it up, I´ve now added it to the page.
