It contains Mirror Lake, a narrow reservoir with steep sandstone sides up to 50 feet (15 m) tall. The lake has a surface area of 137 acres (55 ha) and an average depth of 10 to 14 feet (3.0 to 4.3 m). Recessed out of the wind, the water of Mirror Lake is usually calm and often as glassy-smooth as a mirror, hence the name."@en .
