 Item Number – SCP-4752 Object Class – Safe Special Containment Procedures A 5,000 square kilometer exclusion zone has been established around SCP-4752. Exploration and research teams that come within 100 kilometers of this exclusion zone are to be redirected to their base camp under the guise of seismic activity. Description – SCP-4752 is a large mountain located at the southern end of the Transendarctic Mountain Range, resembling a right-angle triangle with a curved hypotenuse. Geological studies have indicated that since the late 16th century, SCP-4752's mass has been slowly concentrating beneath its peak at the far west of the mountain with no non-anomalous geological explanation. The rate of transfer has been accelerating since the 1980s. As of 2019, 44% of SCP-4752's mass was concentrated beneath its peak. Addendum-4752-001 Geological studies have indicated significant shifts in mass on the following dates, amongst others. 33 CE December 1792 Between 1873 and 1879 October 24, 1929 October 19, 1987 September 15, 2008 February 20, 2020 Addendum-4752-002 On September 6, 2020, Group of Interests 3425, codename Anochists, launched an assault on the west side of SCP-4752, during which an estimated 30% of SCP-4752's mass was lost. Group of Interests 3425 planted a nuclear explosive at the base of SCP-4752's west side and detonated it after a retreat. Following this, world economic output suffered a decline of 26%.
