There is quite a bit on the Maxwell Grant to be found on the internet and much less on the Baca Grant. The Baca family lost their grant but the US Congress compensated them with the 5, 100,000 acre properties.
If you have an interest in the settlement of the west, there are 2 books that I would recommend.
The Great Plains by Walter Prescott Webb(1932) is still in print and still considered an authority on everything west of the 98th meridian. It gives good explanation as to why congress failed to disperse all the lands in the west. It also gives a lot of info on water rights, but since it was published in '32, it doesn't even mention the Ogalala aquifer or Federal Reserved water rights. These federal lands and federal water rights are, and will continue to be, a chronic problem. With Bush/GOP in the Whitehouse, the problems have subsided but a dem prez will put them back on the front burner.
Also, Great River by Paul Horgan('84) is the history of the Rio Grande.
Thank you.
I will look up these books.
It is too bad that Congress did not disperce more lands, at least to the state or local control.
