Q: What happened to the SH Mountains? I can’t find them on any maps anymore.

A: Nothing happened to them. It’s not like they disappeared or something. It’s just that over the years they got renamed, and rightly so. They are now known as the Kofa Mountains, located about 70 miles northeast of Yuma.

The SH Mountains were so named back in the 1800s either by miners or soldiers who noticed that from a distance they resembled outhouses. I will leave it to you to figure out what SH stood for. Suffice it to say, it is not a word one would expect to read in this newspaper.

In the interest of delicacy, the SH range was also known over the years as the Short Horn or Stone House mountains until the mapmakers finally settled on Kofa.

Q: If Tucson and Phoenix are both in the desert, why is it always just a little bit cooler in Tucson than it is in the Valley?

A: Tucson is usually a little bit cooler than Phoenix because it is a little bit higher up. You may not actually have a sense of ascending when you drive there because you are lulled into a state of semiconsciousness because it is the most boring drive in the world.

In its prime, Fairbank was the site of a hotel, school, mercantile, several houses, stage depots and four railroads. Not bad for a town which, even at the height of its popularity, had only about 500 residents. But those days are gone and Fairbank is now a mere remnant of its glory days as a center of mining activity. Now, however, there’s a valiant effort underway to make sure those days aren’t forgotten, as well.

There was a time when Castle Dome City was bigger than Yuma, but those days are long gone. So is most of Castle Dome City.

Fortunately, Allen Armstrong and his wife, Stephanie, are collectors, and what they collect is history in the form of old buildings. As a result, Castle Dome City lives on. In a way.

The Armstrongs have collected and restored more than 20 old buildings that were once part of the Castle Dome Mining District, a former major silver producer. The mining began in 1862 and was productive until 1978, when the last mine closed. The Armstrongs bought what was left of the town and began collecting artifacts that related to mining.
