The unit is bounded on the south by Utah 199 where it passes near Johnson Pass. Travelling south of Tooele on Utah 36, take Utah 199 west towards Clover and Dugway. About a mile and a half east of the pass, a narrow dirt road cuts north for just over a mile to Vickory Canyon, where visitors may begin an uphill walk into the higher mountains. Above 6,500 feet aspen and Douglas fir grow in the shaded valleys. Wildlife Mountain lions find their way down from the more rugged peaks of the Stansbury Mountains, following deer to gentler winter habitat in the Big Hollow unit.
Many smaller mammals are year-round residents, and serve as prey for hawks and both types of eagles.
Recreation Deer hunting, hiking, and horseback riding are the main recreational uses of Big Hollow. The BLM initially recommended the area for wilderness study because it makes a logical component of a larger adjacent national forest roadless area. But the agency later dropped the area from further study. Coalition proposal Our boundary takes in fewer than three miles of vehicle ways that occur in the unit, and these are largely reclaimed and unused. Mineral conflicts are minor, and there are no other known conflicts with wilderness designation.
