Craig, the one thing I would be most interested in is the role El Paso was involved in during the fur trade.
It was a link between Taos, a one time hub of the Fur Trade, and Mexico.
I had such a book one time, The Taos Trappers by David Weber, it dealt with the Indian Trade and was interesting reading...albeit not to well written, IMO.
The Rocky Mountain Fur Trade, with the trapping of the famous Beaver which worth so much in its time, and has had such an impact on the reading public that it seems many of the fringe areas, such as Taos, NM and El Paso leaves little to be found beyond that point in print.
For example; Deming, New Mexico just a couple of hundred miles from El Paso was in fact something of a trade center between the Pueblo, Jicarilla, Mescalero's, French, and Mexico Government.
However, the trade was for something other than Beaver...probably smaller furs such as coyote, fox skunk, even Ermin. There was also horses, mules, metal ware, and trinkets that would be traded once again when they found their way to the Rocky Mountains or deep into the interior of Mexico.
How do I know this? The Court House in Deming is loaded with paintings and writings from that era.
IMO, Deming New Mexico is noted for two things...the current day Deming Duck Race, and that wonderful old run down Court House.
El Paso's original name was Paso Del Note (Pass to the North) and it is totally unreasonable to think that many of the trade goods of the time didn't pass through El Paso on its way south to Mexico, or on up north to the Canadian border. I also can't believe everything was sent to St. Louis and shipped on the Missouri.
Knowing that part of the country pretty good, I just can't see that happening. But what would I know?
Kinda thinking out loud, if you know what I mean.
Uncle Russ...
