“Squaw Valley” name changes

 Palisades summit, formerly known as Squaw Peak

The 1960 Winter Olympic took place in “Squaw Valley,” a ski resort in California located northwest of Tahoe City in the Sierra Nevada range. Due to a controversy of the use of  the term “squaw” (a word that has been used as a derogatory slur against Native American women), location names including the noun “squaw” are now changed—not only in California but across the United States.

The new names mainly rely on the words “Olympic,” “Washeshu.” and “Palisades.” The term “Olympic,” keeps the memory of the historic California ski resort in connection with the 1960 Winter Olympic alive. “Washeshu” is the Washoe word for “the people,” which has been selected to honor the the new commitment to inclusion and diversity. The term “Palisades” means “line of bold cliffs” and the upper mountain terrain has multiple granite-wall locations, two of which are already named “The Palisades”—for example, see the Palisades summit.

You frequently will find old names in former publications and blog posts; like in my "Marmots at Squaw Valley High Camp" post from 2007. To look up the new name, I put together the following list of current and expected name changes:

• Squaw Valley: now Olympic Valley  
• Squaw Creek: now Washeshu Creek
• Squaw Peak: now Washeshu Peak
• Squaw Valley Ski Resort: now Palisades Tahoe
• The Village at Squaw Valley: now The Village at Palisades Tahoe
• Squaw Valley Lodge: now Palisades Tahoe Lodge
• Resort at Squaw Creek: will it become “The Death Star” as locals lovingly (or ironically) call the luxury resort? 

The name replacement is an ongoing process. You still can find trail markers—labeled with the former valley name—while hiking along the trails connecting historic spots, recreational sites and vista points of the majestic “Washeshu Land.”

Mangum Mill in Aurora named for W. Lester Mangum

Foundation structures of the Mangum Mill left at their original site

Aurora's Mangum Mill in Nevada—also referred to as the Aurora milling plant—is named for W. Lester Mangum. After ceasing its operation in 1918, most parts of the mill were moved to Goldfield, but the foundations stayed behind and can still be visited today at Aurora.

W. Lester Mangum was the general Manager of the Aurora Consolidated Mining Company [1,2]. The company was established in 1912. Ground for the Mangum Mill was broken June 20, 1913. On June 15, 1914,  the 500-ton mill—then the second largest mill in Nevada—started crushing rock. The rock was trammed from the mining site to the top of the mill, where the ore cars dumped their content [1]. 

The Mangum Mill was an all-slime cyaniding plant, designed by Morris P. Kirk of the engineering firm of Kirk & Leavell [1].

Volume strength and its other terms for the concentration of hydrogen peroxide in mixtures with water

Volume strength is a dimensionless quantity defined to express the concentration of hydrogen peroxide in a water/hydrogen peroxide (H₂O/H₂O₂) system. Volume strength refers to the volume of oxygen gas liberated from a unit volume of a H₂O/H₂O₂ mixture [1-4]. 

Other terms for volume strength are volume strength ratio, volume percent and volume concentration. Although not commonly seen in the modern literature, these terms and associated values are still of interest while evaluating and comparing property data of H₂O/H₂O₂ compositions. In addition, they are instructive in handling & safety considerations by allowing to project the maximum amount of possible oxygen gas evolution from a given amount of  a H₂O/H₂O₂ mixture with known composition.

Named to honor Andrew Allen Veatch: Veatch's stickleaf (Mentzelia veatchiana)

Veatch's stickleaf on a dry slope near Reno, Nevada

Mentzelia veatchiana is a flowering-plant species in the Loasa family (Loasaceae). It is native to western North America. The species is common on dry slopes and flats in the Great Basin; for example, on south-facing slopes of the Peavine Mountain near Reno's Keystone trailheads.

Mentzelia veatchiana has two frequently used common names:

• Veatch's stickleaf (also written Veatch's stick-leaf)
• Veatch's blazingstar (also written Veatch's blazing star)
  

These two common names as well as the epithet of the scientific name refer to Andrew Allen Veatch (1832-1872). 

Steven Veatch writes in a blog post that Andrew's father, Dr. John Allen Veatch, headed for the Comstock Lode in Nevada to explore the new gold and silver mining district. There, Dr. Veatch practiced medicine and worked in geology. Steven Veatch continues [1]:

His son Andrew was superintendent of the reduction works of the Central Mill in the district. Andrew Veatch studied mining and became a prominent mining engineer. I'm not certain how Andrew died, only that he didn't outlive his father and was sadly buried in 1872, at the young age of 40, in California. Mentzelia veatchiana or Veatch's blazingstar, when discovered and described by scientists, was named to honor Andrew Veatch.

The boldface mark-up of the scientific and common name in the quoted text were made by myself. Less common common names for Mentzelia veatchiana are whitestem stickleaf, whitestem blazingstar and—I like this one—yellowcomet [2-5].
