Box-Death Hollow Wilderness is a 25,751-acre protected area in south-central Utah on the Dixie National Forest, known for its rugged canyon country, vertical Navajo sandstone walls, and the defining landforms of The Box and Death Hollow. Pine Creek forms The Box, a true box canyon accessible only at its lower end, while Death Hollow Creek cuts a separate steep canyon nearby. The severe terrain, prone to flash flooding, supports plateau woodlands, trout streams, mule deer, cougar, elk, and sensitive bird species. Largely trail-less and valued for its remoteness, the wilderness remained undeveloped after a debated 1984 carbon dioxide drilling proposal was excluded from its final boundary.
