**Key discrepancies and estimates noted:**
– **Boulder weight:** Reported as approximately 800 pounds in multiple sources. Not independently measured; this is an estimate from reporting, not a verified measurement. The figure is consistent with the fact that moving the boulder required 13 people, a hydraulic jack, and a grip hoist.
– **Timing of amputation (day five vs. day six):** Wikipedia’s own article contains internal inconsistency on this point. Outside’s contemporaneous reporting places key events on specific days; the reconstruction here follows the Outside account and notes the discrepancy.
– **Distance hiked:** Reported variously as 5, 6, or 7 miles in different accounts. The discrepancy likely reflects different measurement points (distance from pinch point to trail, distance from trail to helicopter pickup, distance from truck to pinch point, etc.). The exact figure is uncertain; this article uses approximate language rather than specifying a precise number.
