Allegheny Front

Allegheny Front

The Allegheny Front stands as the prominent escarpment facing southeast or east within the Allegheny Mountains, spanning southern Pennsylvania, western Maryland, and eastern West Virginia in the USA. Serving as a demarcation, the Allegheny Front acts as the dividing line between the Ridge-and-Valley Appalachians to the east and the Appalachian Plateau (often referred to as the Allegheny Plateau) to the west. This geological feature is intimately linked with the Eastern Continental Divide of the Appalachian Mountains. In this region, the Eastern Continental Divide separates the watersheds of the Ohio/Mississippi river system, which flow towards the Gulf of Mexico, from those of rivers that eventually empty into Chesapeake Bay and further into the Atlantic Ocean.

Nonetheless, it's important to note that the Allegheny Front and the Divide don't always perfectly align. For instance, the North Branch of the Potomac River originates significantly west of the Allegheny Front, near the Fairfax Stone located at the southwestern tip of Maryland. It's merely around 10 miles (16 km) away and situated across the physical divide from the headwaters of the Youghiogheny River, which flows westward into the Monongahela and Ohio rivers.

RFK Jr. Says Fluoride Is ‘Dangerous’ – What the Science Says

RFK Jr. Says Fluoride Is ‘Dangerous’ – What the Science Says

 The most important and immediate impact would be a significant increase in dental cavities, especially among children.

“Water fluoridation is often referred to as a ‘public health miracle’ because it helps so many across all socioeconomic groups avoid the devastating effects of dental disease,” Zavras said. “Groups that consume high levels of carbohydrates will bear the burden of such increase disproportionately.”

However, Malin said there is evidence suggesting that water fluoridation is no longer essential for preventing tooth decay, with fluoride toothpaste being widely accessible.6 “It seems that the demonstrated benefit has declined over the years,” Malin added. “There’s more evidence in support of the topical application.”

Fluoride recommendations have been altered before. The HHS initially set the optimal range of water fluoridation at 0.7 to 1.2 mg/L. In 2015, the agency updated its recommendation to the current optimal concentration of 0.7 mg/L due to the increasing amounts of fluoride in food that is processed with fluoridated water.18 “We need to remember that community drinking water isn’t the only source of fluoride exposure,” Malin added.

Whether Kennedy is in charge of American health initiatives or not, the EPA will have to address the health risks of water fluoridation per the federal court ruling.

“I think it makes sense to further regulate the chemical to mitigate the risk,” Malin said. “Whether that means reducing the concentration or eliminating it from the water supply altogether remains to be determined.”

Thematic  Rochester

By the time you get east to Rochester the Niagara Escarpment is not nearly as pronounced, although it certainly exists in the terrain when you look at a map.

November Scene

So many colors of brown and gray as the leaves are gone from the trees and fields harvested.
