The Grandstand

The Grandstand consists of two distinct mounds of very dark gray rock with a shallow saddle between them, surrounded on all sides by the nearly featureless, light tan-colored clay sediment of Racetrack Playa. The contrast of the dark rock against the light playa makes The Grandstand appear nearly black in bright sunlight. Due to this contrast, The Grandstand is easily discernible, and unmistakable, from great distances. It can be easily seen from aircraft flying within 100 miles (160 km), even at a 40,000-foot (12 km) altitude.

The Grandstand is located in the northwest corner of Racetrack Playa and is the only feature, other than small scattered rocks and a dolomite outcrop on the northernmost shore, that interrupt the playa. The southernmost of the two rock mounds that compose The Grandstand is the tallest, by a few feet. It rises approximately 20-metre (66 ft) above the very flat surface of the playa, whose north end is only 1.5-inch (3.8 cm) higher than the southern end. Racetrack Playa is at an elevation of 3,714 feet (1,132 m)^[2] above sea level, and is 2.8-mile (4.5 km) long (north-south), and 1.3-mile (2.1 km) wide (east-west).

The Grandstand is composed of Quartz-Monzonite, also called Adamellite. It is an intrusive igneous rock that cooled slowly deep underground. Quartz monzonite consists of quartz and the two types of feldspar, but has less quartz than the 20% in granite. Such composites having less than 20% quartz composition are referred to as granitoids. It was exposed on the surface during the Pleistocene epoch, as were Ubehebe Peak and the Panamint Range Mountains to the west, and the Cottonwood Mountains to the east, but solidified in the latter part of the Mesozoic Era.^[3]

On the south side of The Grandstand, obvious signs of wave-cut erosion are visible, creating a noticeable overhang of 30 feet above the Racetrack Playa's elevation. The formation indicates the Racetrack Playa region experienced much more precipitation in past geologic eras.

While The Grandstand may seem imposing to someone standing nearby, as it rises abruptly out of the flat surface of playa, this outcropping is dwarfed by the height of the surrounding mountains. It is the light colored clay sediment forming the playa surface surrounding the dark grey Grandstand that creates its prominence.

As with the rest of Death Valley National Park, The Racetrack and The Grandstand receive very scant rainfall, rarely more than 2 inches in most years. Due to its elevation of 3,000-foot (910 m), the climate at The Grandstand averages slightly cooler than that of the floor of Death Valley; however, daytime high temperatures are commonly above 100 °F in mid-summer. Winds can be extreme also, due to the north-south orientation of The Racetrack, as the "moving rocks" at the south end of the playa demonstrate.

Great blue herons have been sighted atop the highest part of The Grandstand, en route during their annual migration. ^{[citation needed]}
