This report summarizes the meteorological, upper-air (SoDAR), nitrogen dioxide (NO₂), sulfur dioxide (SO₂), ozone (O₃), and particulate matter (PM) data collected at the Resolution Copper Project near Superior, Arizona, for the fourth quarter, October 1 through December 31, 2016.

Flooding is among the worst natural disasters responsible for loss of life and property in Arizona, underscoring the importance of accurate estimation of flood magnitude for proper structural design and floodplain mapping. Twenty-four years of additional peak-flow data have been recorded since the last comprehensive regional flood frequency analysis conducted in Arizona. Periodically, flood frequency estimates and regional regression equations must be revised to maintain the accurate estimation of flood frequency and magnitude.

The Apache Leap South End parcels are three non-contiguous private inholdings within the Tonto National Forest. The Property is situated along the southern end of the Apache Leap, a prominent geologic feature that visually dominates the skyline east of the town of Superior, Arizona.

In this review, we present the physiological and molecular mechanisms of photoinhibition and discuss the interaction between light and other stress factors and its effects on plants destined for reforestation. In addition, the present work analyzes some of the features and strategies that help plants avoid or restrict the occurrence of photoinhibition.

The concentration of PM₁₀ in the air in Hayden has been below federal standards for several years. ADEQ is developing a redesignation request so that EPA will reclassify the area as an attainment area.

The Arizona National Scenic Trail is a complete non-motorized path, stretching 800 diverse miles across Arizona from Mexico to Utah. It links deserts, mountains, canyons, forests, communities and people.

This technical memo summarizes the evaluation of the model construction and approach for the groundwater model used to evaluate future groundwater conditions at and surrounding the proposed Resolution Copper panel cave mine. The groundwater model does not consider impacts from the future tailings facility or water supply pumping over 5 miles distant from the site.
