**Unresolved contradictions and uncertainties:**
– **Journey duration:** The 1849 Stearns narrative gives approximately 27 hours; Encyclopedia Virginia notes 26 hours based on contemporaneous accounts; the NPS page uses 27 hours. The article uses “approximately twenty-seven hours” in line with the most widely cited figure while acknowledging the discrepancy.
– **March date:** The NPS page has historically noted March 29; Wikipedia and Encyclopedia Virginia give March 23-24. Encyclopedia Virginia’s sourcing is more closely documented; this article uses March 23-24.
