Physician, photographer and artist, Eric Overton joins Pete this week on The Mountain Life . A Utah native, Overton has made a documentary film titled Collodian: The Process of Preservation , about our connection to the natural world and the conversations that surround it. Using a century old photography process called wet-plate collodion, Overton treks through the wilderness with his son, capturing the landscape of the west, including Bear’s Ears and other contested spaces.
