HH:  Rock Candy -  crystallization

HH:  Rock Candy -  crystallization

Rock found in a river in Lithuania.
Supposition:

The regular shapes of the patterns in the rock suggest that they are most likely fragments of fossils. The rock is very likely a sedimentary rock formed in a shallow sea. The hollow rings are similar to the stalks of Echinoderms. If you look more closely upstream you probably will be able to find more of them. Drape a couple or two of hydrochloric acid droplets on the rock, if the rock is composed of Limestone-which most of the rocks containing fossils are composed of-it should give off minute bubbles of carbon dioxide gas.
Consult a paleontologist

Fire in the Desert
Arizona is known for its beautiful turquoise, as well as copper and copper-oxide minerals like chrysacolla, malachite, and azurite.  But also found here in Arizona, not far from Quartzsite, is another beautiful gemstone:  Fire Agate.  
There are only two known Fire Agate deposits in the entire world.  One covers an area  between the Sierra Madre Occidental and the Sierra Madre Oriental Mountain Ranges in Mexico about 100 miles north of Mexico City.  The other is the Sonoran Desert region in Arizona and California.  The closest sites to Quartzsite are the Opal Hill Mine, in Palo Verde, California, the Little Horn Mountains about 35 miles east of Quartzsite, and Oatman, AZ.  The Arizona and California Fire Agates have more brilliance, fire, and color than ones from Mexico.

Garden objects - front yard
Next week going to start an herb garden by the front porch … starting with a few basics such as basil, rosemary, cilantro, garlic and chives.  Going to put mint by the water spicket.  Let’s see how that goes.  It will be 8 months until the heat returns.
