Sentinels documents the piñon pine and juniper trees of Bears Ears and Grant Staircase-Escalante National Monuments in Utah, USA, as witnessed over the course of three expeditions during 2019 and 2020. Climate change, aridification, and human development threaten the desert ecosystems of the American Southwest where these trees stand. The artwork and essays are based on photographs, sketches, watercolors, and journal entries take, drawn, and recorded in the field. 

The essays in Sentinels were conceived as “word paintings” that represent the grace and grandeur or the Escalante region through three different styles of American writing—the scientific article, the travel journal, and the newspaper editorial.
