The image above is a photograph of the Glen Canyon Dam (GCD) in Arizona. Recent captures of non-native fishes in the Colorado River downstream of GCD indicate a potential threat to imperiled native fish in the Grand Canyon.

This is an image of Glen Canyon, located in Arizona. Glen Canyon is a natural canyon carved by the Colorado River and located largely in Utah. A small part of the lower end of Glen Canyon extends into northern Arizona and ends at Lee's Ferry, near Glen Canyon Dam. 

A soil moisture data logger buried in the ground is a specialized instrument designed to measure and record the moisture content of soil over time. Here's how it generally functions:

Hexavalent chromium, a known carcinogen under specific circumstances, occurs naturally in groundwater in the Mojave Desert. However, concentrations of hexavalent chromium increased in California’s Hinkley Valley beginning in 1952 when the Pacific Gas and Electric Company (PG&E) discharged it into unlined ponds.
