“Tuolumne River, Dusk” — Dusk light on the Tuolumne River and Meadow, Lembert Dome, and the Sierra crest.
Photographing in the morning and evening twilight can be a bit of a crapshoot. The light can be soft yet intensely colorful… or it can simply fade away to gray. Familiarity with the patterns of clouds and light can improve the odds, but you still have to head out there and take advantage of whatever happens. That was my plan on this late-August evening when thin clouds stretched across the sky, presenting the possibility of colorful light.

“[The author has] already discussed ancient water management systems, such as the qanats in Persia and other Eastern countries. In Europe, there are the acequias of the Sierra Nevada in Andalusia, Spain.
The hand-dug channels date back over 1,000 years to the Moorish era. Networks of canals, aqueducts and cisterns were engineered to capture and transport snowmelt, turning this natural resource into a sustainable water supply for agriculture. The high-altitude ditches had openings, allowing water to infiltrate into fractures and faults, replenishing the aquifer, and to irrigate the lower levels of the slopes.
𝗪𝗵𝗮𝘁 𝗱𝗲𝗳𝗶𝗻𝗲 𝗮𝗰𝗲𝗾𝘂𝗶𝗮𝘀?
✅ Gravity-fed irrigation that supported terraced farms and local biodiversity.
✅ Designed to distribute water slowly and equitably, even during dry summers.
✅ Stretching over thousands of kilometres, these systems fell into disuse in the 1980s but are now part of restoration efforts led by the MEMOLA Project (Universidad de Granada).
With climate change and more intense droughts, the Acequias could provide an ancient solution to the modern-day water crisis…”

Hype for the Future 135G: State of California Explained At-Large
Introduction The State of California is located along the West Coast of the United States of America and is the most populous state in the nation though containing a smaller land area than the States of Alaska and Texas. By population density, the state is toward the higher end, albeit not nearly as densely populated overall as the State of New Jersey or even the Southern New England states. Other states with higher densities than California include Maryland, Delaware, Pennsylvania, and […] -
What's going on in #IndianCountry?!!
Joy Rides into the Stratosphere, and #MilitaryIntelligence: Helium Balloons over #Navajo and #Lakota Nations, Indian Country
"#WorldView also announced a partnership with the military defense contractor #SierraNevada for intelligence, surveillance and reconnaissance, for the U.S. military using its balloons. One of these balloon flights was for the U.K. defense department in the Grand Canyon."
By #BrendaNorrell, #CensoredNews, Sept. 5, 2024
"Joy rides into the stratosphere, and military surveillance, are two of the purposes for the helium balloons over the #NavajoNation, #LakotaNations in #SouthDakota, and most of Indian country, according to the owners of the helium balloons.
"#TheGuardian exposed the helium balloons #spying platforms and the #ACLU in South Dakota warned of this #surveillance. The balloons are capable of video recording vehicles traveling to #protests, and can reveal where the vehicles arrived from. It's spying without a warrant.
"The balloon owners, Aerostar and World View, have U.S. military contracts for recovering payloads, as was the case with World View's experimental payload recovery in the #GrandCanyon for England's defense department. These balloons can also carry out ground surveys.
"Aerostar is based near #SiouxFalls, South Dakota, and World View is headquartered in Tucson, Arizona."
