Waw an Namus, Oasis of Mosquitoes, is a volcanic field, cone and caldera in southern Libya, deep in the Sahara Desert. The inside of the caldera houses an oasis of rich foliage and three small salt lakes of variable color which are the reason for the volcano’s name. A volcanic field of dark basaltic tephra flow extends 10–20 kilometres (6.2–12.4 mi) around the caldera. The dark field’s vast size allows it to be easily seen from space. Due to the fresh water at the volcano, Waw An-Namus was always an important watering point for the caravans.

The Wave is a sandstone rock formation located in Arizona, United States, near its northern border with Utah. The formation is well–known among hikers and photographers for its colorful, undulating forms and the difficult hike required to reach it. Due to the fragile nature of the formation and the large number of people wishing to visit it, a daily lottery system is used to dispense only ten next–day permits.

The Eternal Flame Falls is a small waterfall located in the Shale Creek Preserve, a section of Chestnut Ridge Park in Western New York. A small grotto at the waterfall’s base emits natural gas, which can be lit to produce a small flame. This flame is visible nearly year round, although it can be extinguished and must occasionally be re-lit.
Prohodna is a cave in north central Bulgaria, popular tourist attraction for the two eye-like holes in its ceiling that create an eerie effect. Prohodna is 262 meters (860 ft) long, and has two entrances which lie opposite one another, known respectively as the Small Entrance and the Big Entrance. The cave owes its name, which literally means Thoroughfare Cave or Passage Cave, to this feature. Prohodna is most notable for the two equal-sized holes in the ceiling of its middle chamber. The holes, formed through erosion, let in light into the cave and are locally known as the Eyes of God or Oknata.
