The Brian Head Quadrangle straddles the west edge of the Markagunt Plateau and is roughly centered on Brian Head Peak, at 11,307 feet (3446 m) the highest mountain in southwestern Utah. The peak, encompassing an area of great natural beauty and recreational use, is capped by volcanic rocks that erupted from calderas on the Utah-Nevada border. These volcanic rocks overlie landslide-prone local volcaniclastic strata, which in turn overlie colorful strata of the Claron Formation, centerpiece of Cedar Breaks National Monument in the southwest corner of the map area. The plateau is capped by remnants of the 20-million-year-old Markagunt Megabreccia, Utah's largest catastrophic gravity slide.
