JMO:
With a height of 5' (62") and 25-25 1/2" waist,I'd put her weight between 100-120.
In 1959, Tucson was still very small, and the influences from "the South" (Southerners trying to gentrify Arizona) made it bad etiquette for women to wear jeans, unless at a rodeo or parade. With a "side zip", I would think they were "dress" jeans. If you were a woman working horses or cattle, you wore men's jeans (cheaper and tougher). And denim was very durable back then.
If they are dress jeans, the pearl button may have come from a dressy western shirt.
The moccasin shoes would have made the ensemble.
What is missing is a hat, a hat of any kind. If this female was hiking in the hills, she would have worn a hat. "White" women still tried to shield their skin from any type of "tan". (Begs the question "was she hiking, or taken there against her will?" I *believe the later*) The hat (felt or straw) may have blown away, feel apart from the elements or rodents, or she never had one. Also a belt. It was the style with western pants.
Short permed hair was pretty much the norm, especially in the hot climate.
As a Native Arizonan, I can tell you, "The Desert always gives up it's secrets". Humidity between 7-12% is common, we traditionally have minimal amounts of rain, and much of the snow is "dry", it justs falls apart in your hands until it gets above freezing. It's a very good place for preserving bones, many times dried flesh, articles of clothing, and the like. Think of it as a giant dehydrator. Sun, shade, or under the dirt, Arizona does a pretty good job of preserving things.
The 12 coins, the newest being 1959. I'd say she died in 1959-1961.
She may have been a parade/rodeo spectator, participant, or a cowboy groupie, girlfriend, or wife. She *may* have worked at a western theme steak house. Was she an extra for a film production at Old Tucson Studios, or an employee when it was opened to the public in 1960? Any of those would make it easy to delay a missing persons report until the next town, next State, or not at all.
An back in 1959-1961, there was nothing out there where her remains were found.
JMO.
