Esoterizona Stones 35

Fluorescent Minerals

Calcite (red) and fluorite (purple) from the Pure Potential Mine. 6"x3.5"x2" (La Paz County)

With longwave UV, only the fluorite is visible.

White light - you can see the white bands of fluorite cutting through the brown calcite.

Fluorapatite (violet) and hyalite opal (green) from the Cerro de Mercado Mine, Durango, Mexico.  Midwave UV activates the fluorapatite, while the hyalite opal responds to shortwave UV. 4"x3"x2.5"

Fluorapatite, midwave UV only.

Also a very aesthetic white light specimen

Calcite (red), fluorite (purple), and willemite (green) from the "3-Color-Mine" near Silverbell, AZ. 3"x2.5"x1"

White light.

All three specimens purchased from Polman Minerals.

Paul Don's Food Center

The demolition of Guilin Restaurant on Speedway Blvd in Tucson revealed this old painted advertisement for Paul Don's Food Center, Home of Pampered Poultry.

Printed advertisements for Paul Don's appear in the Tucson Daily Citizen during the years 1948-1958, first as an independent grocery, and later (around 1951) as a member of Associated Grocers (AG), a group that formed in 1948 as a means for independent grocers to join together and compete with larger regional chains.

The former breezeway between the two buildings, where the sign was hidden from view.

The wall has since been painted to match the rest of the building.

According to a quick search, the term "Pampered Poultry" is now used by people who dress up and accessorize their pet chickens.  I doubt that is what Paul Don meant.

Rillito Flow

Pictured below is the normally dry and dusty Rillito River crossing on Camino de la Tierra, near I-10 in Tucson.  Photos taken the morning after torrential monsoon storms swept across the Santa Catalina mountains.  Here, over fifteen miles from the headwaters, the muddy river is easily two hundred feet across and still flows swiftly.

Cactus Bloom, with Bees

Pictured below is the flower of the night-blooming Peruvian apple cactus (Cereus peruvianus), also featured in Bloom Time 3 on this website.

In that post I stated that the flower is pollinated by the nocturnal white-lined sphinx moth, which is true.  But, on this cloudy morning, the dancing honeybees also play their role.

Canyon Metates

Hand-bored metates (or pestles), roughly one thousand years old, in a large bedrock boulder.  Presumably they were used by native inhabitants to grind foodstuffs such as mesquite beans or corn into usable meal.  This boulder was part of large jumble situated on a canyon rim overlooking a choke point and natural waterfall.

Most contained some water, but only this one was streaked with vivid plant life.

U of A Mineral Museum 4

The University of Arizona Mineral Museum features many amazing specimens from all over the world. Tourmaline (aka elbaite) is one of my favorites.

The U of A Mineral Museum also has a fluorescent mineral display.

 The following photos are from the U of A Mineral Museum, on campus at 1601 E University Blvd. These are specimens from historically significant Arizona localities that are now and forever closed to collecting, such as Bisbee, Glove, and Tiger-St Anthony.
