Explore Your World With Lewis and Clark
Montana rancher and artist, Don Greytak, and Idaho artist Barbara Peets produced illustrations to increase public awareness of native and non-native plant species along the Missouri. Don sat with the project manager and designer, Carla Hoopes, at the Missouri Headwaters on the overlook from which Don portrayed the convergence of the Jefferson, Madison, and Gallatin rivers at the arrival of Meriweather Lewis and William Clark on July 27, 1805.
Don notes that he watched the Milk River throughout the course of his life braid a path back and forth across the landscape. Don's insights prompted him to visualize the Missouri Headwaters at a point in time after the braiding up to 1805--not where the river flows today.
The Salmon Challis National Forest education coordinator Pat Hurt coordinated Idaho's Tower Creek Pirimids artistic contribution by Barbara Peets. Barbara's love of Idaho's landscapes and Don's life experiences, combined with knowledge gleaned from the Lewis and Clark journals, bring education to life to decrease weed spread by visitors.
The project steering committee was led by Alan Knudsen when he managed the Missoula weed education program. Montana Department of Agriculture state weed coordinator Barbra Mullin and industry’s Bob Ullom joined Alan and Carla to set direction for the project.
Background. The Lewis and Clark Placemat Project
Interpretations from guides, historians, and land managers help visitors become stewards of the historic trails, rivers, and parks along their way.
Journey through Time to Explore Lewis and Clark's Changing Landscapes
Follow the icons to learn historical uses of native plants and what you can do to
stop weed spread at each of these national historic sites along the Missouri River.
Play the games and learn the vocabulary to identify three native and three invasive
plants at each site.
Conservation partners came together to create a series of information resources and games to help travelers engage in identification of native plants and non-native invasive plants they may encounter at a site.
Restaurants used the flyers as placemats and tourist vendors handed them out to visitors during interpretive talks. Don Greytak spent time at each site visiting with historians, reading the journals, and comparing his life experiences on the Milk River to envision and portray in illustration how the events on the actual day or days that played out for Meriwether Lewis and William Clark.
Travelers came from all over the world to visit the historic trail during the Bicentennial Celebration.
Education flyers were collected by travelers at scenic and historic venue, court house lobbies and restaurants. The Bicentennial Celebration national committee selected the project for archive in the permanent collection at the Lewis and Clark National Historic Trail Interpretive Center in Great Falls.
Each year in April, news releases included television and radio public service announcements written by Carla Hoopes and created by Earthtalk Studios. News media professionals learned that noxious and invasive weeds begin to surface as snow retreats across Montana’s landscapes. The 30-second spots were peer-reviewed by stakeholders and agency land managers who work together across jurisdictions. The messages represent statewide consensus on what volunteers can do about spotted knapweed on public trails.

A letter from Montana’s Governor, December 12, 2001. Dear Mr. Greytak: I would like to express my sincere thanks for your support of the Montana weed control effort and the Statewide Weed Education and Awareness Campaign. Your illustrations for the Lewis & Clark placemat project have made it a very special and effective awareness program for the state and our visitors, as we get closer to the Lewis and Clark Bicentennial. I was pleased to receive one of your specially signed placemats illustrating Rainbow Falls. I have also heard about the Three Forks design, and look forward to seeing the complete set as they are developed and printed. Thank you again for your very generous contribution to this important program. Sincerely, Judy Martz, Governor. c: Ralph Peck, Director, Montana Department of Agriculture
