Spotted Lake is a saline alkali lake located northwest of Osoyoos in the eastern Similkameen Valley of British Columbia, Canada. The lake is richly concentrated with various minerals. Most of the water in the lake evaporates over the summer, revealing colorful mineral deposits. Large “spots” on the lake appear and are colored according to the mineral composition and seasonal amount of precipitation. Magnesium sulfate, which crystallizes in the summer, is a major contributor to spot color. In the summer, remaining minerals in the lake harden to form natural “walkways” around and between the spots.

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.

Speicherstadt (lit. city of warehouses) in Hamburg, Germany is the largest warehouse district in the world where the buildings stand on oak logs along canals near the Elbe. The district was built from 1883 to 1927 as a free zone to transfer goods without paying customs. The warehouses were built with different support structures, but Andreas Meyer created a Neo-Gothic red outer layer with little towers, alcoves, andglazed terra cotta ornaments. The warehouses are multi-storey buildings with entrances from water and land. Over the last years the area has been renovated to have museums, offices and entertainment options, but the old feel of the area remains. At sunset, the Speicherstadt is engulfed in a mysterious atmosphere when the facades of the red brick buildings and steel bridges are artfully illuminated.
