Energetic middle schoolers fill the classroom air with excitement.  Three UA graduate students are standing in the way between their final hours of summer school and unlimited summer fun.  We better make this engaging!

Today, we are there to talk about environmental science, and how the quality of our environment- the air that we breathe, the water that we drink, the soil that we run on- affects our every day lives, including our health (read more) ... 

Mining and Groundwater in Southern Arizona

Monday, December 9, 2019

As I drive southwest along highway 82 from Sonoita, Arizona toward the Town of Patagonia, Red Mountain emerges on the skyline. The north face of the mountain is covered in vegetation, cloaking the red rhyolite that is visible from the south. Even more concealed are the systems of fractures, faults and old mining tunnels that complicate the hydrology of the area. I turn off the highway, ascend a winding dirt road, park my car and walk down a steep valley south of Red Mountain, keeping an eye on my GPS. I soon find myself at the entrance a gaping hole in the rock. The hole appears to be a cave, but it is not. Old mine adits; the mouths of snaking underground tunnels of abandoned mines, leak water, sludge, and a cool, ominous, vapor. The entrance of some are covered in a tongue of green moss; the opportune plant making the most of the moist mouth of the adits. Historic mines create a unique plumbing system in a mountain of fractured rock and act as massive pipes that drain out groundwater from the mountain. (Read more)
