WILLISTON — The Missouri-Yellowstone Confluence Interpretive Center near Williston will host “Paths of Progress: Trails, Tracks, Rivers & Rails” on Saturday, March 14, from 9 a.m.-5 p.m.

The free, family-friendly program will explore the rich history of the Missouri-Yellowstone Confluence through the many ways people traveled across and through the landscape, from Indigenous trails and river travel to wagons, steamboats and railroads. The event is open to all ages.

Hands-on activity stations will be available throughout the day, allowing visitors to drop in and participate at their own paces. Interactive components include building and packing a travois, a “Float Your Bull Boat” engineering challenge, an oxcart-building STEM activity, a horse care station and additional transportation-themed challenges.

Thirty-minute presentations will be offered at 11 a.m., 1 p.m. and 3 p.m. These talks connect the hands-on experiences to historical examples, highlighting how transportation and movement shaped daily life, trade, and cultural connections at the Missouri-Yellowstone Confluence.

This event is part of the ND250 commemoration celebrating America’s 250th anniversary.
