On the night of July 9, 1843, Fremont and his party camped "on a small stream, near the road which runs from St. Vrain's fort to the Arkansas". This would be in today’s Russellville Gulch, just south of Franktown and along the old Trappers Trail and just west of the Elbert County line. More excerpts from his journal as edited by Jackson and Spence, 1970, p. 440-443, for the days he was actually in Elbert County follow.
This camp would have been just south of the Elbert County line, north of today’s town of Peyton, and marked the exit of Fremont from his only visit to the immediate area.
