Dive (~20 feet) into the crust of the Earth as we explore the hidden wonders of test pits, decoding the language of foundation layer by layer. Every pit tells a story millions of years in the making. @timmywallace & @adrianpatterson with @cnitucson digging test pits last summer.

It looks like these Arizona natives (Adrian Patterson & @timowallace of @cnitucson) are enjoying their first experience snow shoeing in the backcountry. Is it really considered work when you're having this much fun?

Arizona piezometer installs are heating up! Time to pack some extra water and sunscreen. Alexia Acevedo Navarro PPE FTW.

Check out CNI's pop-up core logging facility! In response to limited access to client sites over the last year, we turned one of our warehouses into a core shed. Not even a pandemic can get between our geos and their core 😉.
