This is Kit Carson who died in 1868. It would have been impossible to take the photograph supposedly depicting Carson at that time. Those were the days of wet plate photography with long exposure times, so long that people always sat for photographs and wore unseen braces to keep them from wiggling. That's why the subjects always had that very stiff look.
Saguache, pronounced
sa WATCH, has a small but excellent museum. The chamber of commerce's website notwithstanding, there's not too terribly much going on there, but it's a good place for a stop. Folks are certainly friendly.
The town of Bonanza, shown on the chamber's website, no longer exists except for a few scattered homes. We spent a day poking around mine dumps and generally exploring.
Otto Mears, also pictured on the chamber's website, was an important man in southwestern Colorado. After being mustered out of the army at the end of the Civil War, he came to southwestern Colorado, a good ways form Saguache, where he went into the toll road building business. He later switched to building railroads and built four in the area. He was an investor and promoter of mines, After the silver crash of '93, he made money in gold.
Josie Crum, no professional writer but chatty and informative, wrote several books about his railroads. I've linked to the two that I have and heartily recommend. Josie Crum was a widow of one of the Rio Grande Southern employees. I've also linked to one of his biographies which I enjoyed.
There are many other books on these subjects. Colorado history is fascinating as there is so much about both mining and railroads.
