‘Finding Fremont’

You know downtown’s Fremont Street, but do you know the street’s namesake, John C. Fremont? “Finding Fremont: Pathfinder of the West,” a new exhibit at the Nevada State Museum, Las Vegas, highlights Fremont’s 1842-44 expeditions to map and describe what became the Oregon Trail — journeys that set the stage for his later careers as soldier and politician. The museum, adjacent to the Springs Preserve at 309 S. Valley View Blvd., is open from 9 a.m. to 5 p.m. Tuesdays through Sundays; admission is $9.95 for Nevada residents, $19.95 for non-residents and free for children under 18.
