Desert Well

Desert wells are sandstone structures that generate in desert biomes.

Generation
Desert wells generate only in desert biomes. They have a $1/1000$ or $1/500$ chance to be generated in any desert chunk, which makes them a rare sight. It is possible for a well to generate around a cactus. The well structure will still generate with the "Generate Structures" option disabled.

$$, desert wells have a chance to generate in a cluster between 16 blocks.

Desert well generation is capped at the coordinate Y-128. If desert terrain is higher than Y-128, no desert well will be generated.

Structure
Desert wells are built of sandstone blocks and slabs with a water source inside.

Trivia

 * Desert wells are one of the three structures that have do not use a loot chest (the others being swamp huts and fossils). They also are the only single structure that is designed to holding water (not confused with waterlogged).
