Feds Charge Yosemite BASE Jumper Identified From Instagram Video

Prosecutors cite the clip plus license-plate hits tying Jack Propeck to an October Glacier Point leap, with an affidavit finding no sign of AI manipulation.

Overview

  • A Dec. 12 criminal complaint in the Eastern District of California charges Propeck with unauthorized parachute use in a national park, a Class B misdemeanor.
  • The Instagram video reportedly shows a person running off Glacier Point, panning to his face as a parachute deploys on Oct. 8, 2025.
  • Investigators say a plate reader logged Propeck’s car entering Oct. 7 and exiting Oct. 8, and photos matched his appearance and gear to the footage.
  • After a ranger contacted him, Propeck claimed his face was AI-superimposed, but the affidavit states there is no evidence the video was made or altered with AI.
  • Propeck is representing himself and is due for arraignment on April 7, as Yosemite officials warn such illegal jumps endanger visitors and first responders.
