Sunday Challenge: Find the intruder

Present a photo of any subject including something that should not be there and ask viewers to find it. It can be something obvious or obscure. A black chair in a sea of red chairs, a mis-colored brick in a wall, a hammer amongst the kitchen utensils, etc.

Romanechite is a hydrated barium manganese oxide mineral that is frequently mined in a bubbly mass form. It was first discovered in France, but is also mined in Germany, France, India, Mexico, and the United States. It is used to make steel and sodium batteries.

Sunday Challenge: Ugly ducking. Take a photograph of something that we normally view as ugly and make it beautiful, or at least interesting

Spy Satellite Target

Taken in the desert near Casa Grande, Arizona. These markers are located close to the RV park where we spent many winters.

The "target" is a group of concrete pads in that shape. There is a benchmark in the exact center. The operators of the spy satellites would take photos of these markers, and then check their locations against the exact positioning of the benchmark.

Image taken with phone and processed with GIMP.

"Some saguaros grow in rare formations called a cristate, or "crested" saguaro. This growth formation is believed to be found in one in roughly 10,000 saguaros, with 2,743 known crested saguaros documented. The crest formation, caused by fasciation, creates a seam of abnormal growth along the top or top of the arm of the saguaro."

"Life Span With the right growing conditions, it is estimated that saguaros can live to be as much as 150-200 years old. Size Saguaro are very slow growing cactus. A 10 year old plant might only be 1.5 inches tall. Saguaro can grow to be between 40-60 feet tall (12-18m). When rain is plentiful and the saguaro is fully hydrated it can weigh between 3200-4800 pounds. Quick Facts • The saguaro is the largest cactus in the United States. • Most of the saguaros roots are only 4-6 inches deep and radiate out as far from the plant as it is tall. There is one deep root, or tap root that extends down into the ground more than 2 feet. • After the saguaro dies its woody ribs can be used to build roofs, fences, and parts of furniture. The holes that birds nested in or "saguaro boots" can be found among the dead saguaros. Native Americans used these as water containers long before the canteen was available. "
