SCP-1686

Description

SCP-1686 is an area of land encompassing approximately 750 km² of ██████ County, South Dakota. The physical topography of the area consists primarily of grassland plateaus and has not been found to be of an anomalous nature. The flora and fauna of the region have not been known to possess any anomalous properties, although animal population levels in the area are lower than those of the surrounding environs. The area is currently uninhabited, with the exception of Foundation personnel monitoring the phenomenon and conducting biological research.

Once every 20-50 days, SCP-1686 will enter its active state. During this period, cumulonimbus clouds will form within SCP-1686, generally encompassing around 60% of the total area. These clouds will rotate in a counterclockwise direction within SCP-1686 (as viewed from above) and have never been observed to exit the area of SCP-1686. Upon reaching a stage of development normally associated with the production of liquid precipitation, clouds will begin to produce via an unknown mechanism a large number of marine organisms. These entities, which consist largely of fish and other aquatic organisms (see Addendum SCP-1686-1), then fall to the earth normally. It is estimated that approximately 93% of all organisms produced by SCP-1686 are live at time of production, although very few have been known to survive transit to earth. Organisms which do survive transit generally expire shortly thereafter.

Clouds produced within SCP-1686 generally dissipate after a period of 5-7 hours, although they have been known to persist for up to a week. While not in its active state, SCP-1686 has not been known to exhibit any unusual properties, although remains of precipitated organisms do persist within the area for a non-anomalous period of time.
