Natural Rock Fire pit...utilize boulders, large stones and sand or fire bricks to create an organic shaped pit. These types of designs work well in estate-type backyards or those that face lakes or other natural environments. They seem to connect your yard with the space beyond.
The quiet, simple design, installed by Designs by Sundown, features a sleek custom bench that accentuates the long, narrow footprint and a natural-gas fireplace made of precast limestone.

Derweze, also known as the door to hell, is a 70 meter wide hole in the middle of the Karakum desert in Turkmenistan. The hole was formed in 1971 when a team of soviet geologists had their drilling rig collapse when they hit a cavern filled with natural gas. In an attempt to avoid poisonous discharge, they decided to burn it off, thinking that the gas would be depleted in only a few days. Derweze is still burning today
