This
map was a Greene promo piece. List on the left are the mining properties and
Sonora enterprises of Colonel Greene.
Red
circles show the areas of the Greene Consolidated Copper Co. and Greene Consolidated
Gold Co. in Sonora, Mexico.
Here
is a closeup of areas of Sonora where the Greene properties were. Note Cananea
in the middle of top circle--the copper mine. In the bottom circle note Cucurpe,
on the Santo Domingo River, the site of the gold mine.
This
is a list of Mexican railroads at this time provided on the Greene Consolidated
Gold Co. promo map. The red numerals on the map are where the railroads were
located. Colonel Greene built the Cananea, Yaqui River & Pacific.

Howard O. Flipper was the first black graduate from West Point who, because of his color, was falsely accused of stealing or some such nonsense. He was one of the top candidates in his class and was highly thought of by the West Point instructors and officers; yet, he was black and because of that, they drummed him out. After he joined Colonel Greene and the whole Greene enterprise failed, Flipper hung around that part of the world, dying in 1940 in Atlanta, Georgia.
From the San Angelo, Texas, City Council meeting of July 2001:
INTRODUCTION OF AN ORDINANCE CHANGING THE NAME OF EAST AVENUE B, BETWEEN SOUTH OAKES STREET AND BURGESS STREET, TO HENRY O. FLIPPER STREET
Henry Flipper was stationed at Fort Concho (where San Angelo, Texas, is today) with the all-Black 10th Cavalry, a unit Henry had joined at Fort Sill.
HENRY'S FIRST COMMISSION:
Flipper was commissioned a Second Lieutenant and was assigned to frontier duty with the all black Tenth United States Cavalry at Fort Sill, Oklahoma (Indian Territory). The Ninth and Tenth Cavalry and the 24th and 25th Infantry became known as "Buffalo Soldiers." They fought Apache and Comanche warriors and policed rustlers and outlaws. Buffalo Soldiers built new roads and telegraph lines and protected stagecoaches. Perhaps the Plains Indians dubbed them "buffalo soldiers," because their hair seemed similar to a buffalo's or it may have been a term of respect, since the buffalo played an integral role in the life of the Plains Indians.

In 1885, Colonel Greene's cattle empire was headquartered in Hereford, Arizona [see photo above], according to a source outside of Sonnichsen. Supposedly, the Colonel built the largest house in the town...in the above photo, there is a large house behind the tent-roofed building on the far right, which is much clearer in the postcard from which this was scanned. The house is just down the tracks from the railroad station, which, again via the outside source, was the El Paso & Southwestern. It kept cattle-loading pens in Hereford.
Here
is a Mexican postcard of Colonel Greene's Ronquillo Mine and Smelter in Ronquillo,
just west of Cananea with Colonel Greene's mansion sitting on a plateau between
the two villages. This photo is looking east. Cananea is just in the distance
past the smokestacks.
