Oh of other mistakes I have made.....the LA purchase only includes a corner of New Mexico and the Mexican Cession includes a bigger portion, Gadsden Purchase and Treaty of Guadelupe Hidalgo also plays a part in the mixed bag that went into the territorial acquisitions of New Mexico over the years.
There is a horse rendering plant near Ft MacLeod here. Apparently horse meat is a big seller across the ponds. Wild horses are also captured and rendered. ..Albertans do not eat horse meat. Knowingly. Why would we. Plenty of beef pork poultry etc. "but were, like the Indians themselves, migrants from south America"- I don't think our natives came up through SA. I'm thinking NA land bridge or possibly even Chinese Eskimo descendants. China prolly had peeps here before our "natives" say they had the land. Mr History may have something to add.
Now that I think about it I doubt the horses came from South America as well. Indeed I think I've read that the stocks were originally Spanish and for the most part escaped from Mexico and perhaps some of the Central American colonies but the route up the ismuth is pretty rough from what I've read.
All horses now in the Americas came from Europe, beginning with the Spanish. Oddly though, the horse originated in the Americas and migrated to Eurasia, then went extinct here about 12,000 years ago. 12,000 years ago is when people were spreading into the Americas from the north, so those original horses may well have been hunted into extinction.
Here are two excellent books about the Apaches: http://www.amazon.com/Apaches-A-History-Culture-Portrait/dp/0806129786 http://www.amazon.com/Indeh-Apache-Odyssey-New-Maps/dp/0806121653/ref=sr_1_1?s=books&ie=UTF8&qid=1403107862&sr=1-1&keywords=indeh+ball
You mean to tell me, the Earth has experienced disastrous climate changes that altered Earth forever? ...Well that could be news for Al Gore. ..Maybe Man didn't kill off all the unicorns. Maybe the Earth just experiences climate change that is out of Mans control. Colour me uneducated. Those poor ponies.
