Per 
Special Containment Procedures: SCP-XXXX is to be contained in a standard secure server room at Site-██. The server hosting SCP-XXXX is to be isolated from any external networks and physically guarded by at least two Level-3 personnel at all times. Access to SCP-XXXX is restricted to authorized personnel with Level-4 clearance or above, and any interaction with the program must be logged and reviewed by Foundation computer experts. Research involving SCP-XXXX must be approved by the Site Director and supervised by at least one senior researcher.
Description: SCP-XXXX is a computer system consisting of specialized hardware and software. The hardware components appear to be standard computer equipment, while the software component is a unique program referred to as SCP-XXXX-1. SCP-XXXX-1 is a customized operating system that only allows the user to access a single program, designated SCP-XXXX-2.
SCP-XXXX-2 is a text editor that utilizes JavaScript programming language. Users are only able to write and execute JavaScript code within SCP-XXXX-2. The anomalous properties of SCP-XXXX manifest when the code written within SCP-XXXX-2 is specifically in relation to Yellowstone National Park.
If the user writes JavaScript code that references or affects Yellowstone National Park, a digitized simulation of the park will undergo corresponding changes. These changes include alterations to geographical features, flora, fauna, and even weather patterns within the boundaries of the park. The magnitude and permanence of these alterations are directly proportional to the complexity and specificity of the code written. Furthermore, the anomalous effects of the code can extend beyond the confines of SCP-XXXX, affecting the real-world Yellowstone National Park.
SCP-XXXX was discovered on 5/17/2001 in the possession of an individual who was using the anomalous programs to simulate fictional scenarios within Yellowstone National Park. The Foundation subsequently confiscated the computer system and contained it within Site-██.
Addendum XXXX-A: Selected Experiment Logs
Experiment XXXX-01:
Objective: Determine the extent of SCP-XXXX’s influence on Yellowstone National Park.
Procedure: Researcher William Derrick wrote a simple JavaScript code that instructed > ? > SCP-XXXX-2 to modify the temperature in Yellowstone National Park by +5 degrees Celsius for a duration of 24 hours.
Results: Weather stations within Yellowstone National Park reported a sudden increase in temperature as instructed, causing noticeable effects on local ecosystems. The anomalous temperature change dissipated after the designated 24-hour duration.
Experiment XXXX-02:
Objective: Test the permanence of SCP-XXXX’s effects.
Procedure: Researcher William Derrick wrote a JavaScript code that instructed SCP-XXXX-2 to change the color of the iconic Old Faithful geyser to purple, permanently.
Results: Following the execution of the code, Old Faithful geyser was observed to emit purple colored water during subsequent eruptions. Park officials confirmed that the color change was not a result of natural or artificial causes. The effect has since then ceased following numerous attempts to restore the geyser to its original state.
Experiment XXXX-03:
Objective: Assess the response of SCP-XXXX to malicious instructions.
Procedure: Researcher William Derrick wrote a JavaScript code that instructed SCP-XXXX-2 to increase the volcanic activity within the Yellowstone Caldera.
Results: No immediate response was observed. However, seismic activity monitors located near the caldera registered a slight increase in activity over the following three days. > Seismic levels eventually returned to normal, indicating that SCP-XXXX may possess certain safeguards or limitations to prevent catastrophic events.
Note: Due to the potential for significant damage to a globally recognized national park and potential risks associated with altering natural systems, further experiments involving SCP-XXXX are to be conducted with caution and under strict supervision. The long-term effects and implications of SCP-XXXX’s capabilities require thorough investigation.
Addendum XXXX-B: Incident Report XXXX-Alpha
On 3/9/2003, Researcher William Derrick attempted to execute a complex JavaScript code within SCP-XXXX-2, intending to create a simulation of a prehistoric Yellowstone environment. However, an error occurred during the execution, resulting in a sudden anomalous phenomenon. Yellowstone National Park underwent a massive temporal displacement event, transporting various prehistoric species and geological formations from different eras into the present-day park.
Containment breaches occurred as a result of this incident, requiring the mobilization of Mobile Task Force Omega-6 (“Timekeepers”) to neutralize and re-contain the displaced entities. The incident resulted in 17 casualties and extensive damage to the park.
Research involving SCP-XXXX has been suspended indefinitely pending a comprehensive risk assessment and the implementation of additional safety measures.
This document is Level 4 Classified and should not be disclosed to unauthorized personnel. Any attempts to interact with SCP-XXXX without proper clearance will be met with disciplinary action.
