To understand geologic time, you have to stretch your mind across knowledge sets and time scales. That’s exactly what geologist and paleontologist Kevin Madalena has done as he’s worked to understand and defend the fossil record and cultural sites on Ancestral lands. Here, we speak with him about how he has crossed scientific disciples and knowledges to understand the deep past and help safeguard the future. We cover the recent defacement of cultural sites in the Moab region and how those acts are an extension of looting, ecological destruction, and missing and murdered Indigenous women.
