Merrill J. Mattes Research Library

Over 4,000 Volumes!

The largest frontier trails research library in the nation

Unlock the rich history of our frontier past by supporting our mission to make over 4,000 trail diaries, artifacts, maps, and other invaluable research materials accessible to students, researchers, and historians. Currently housed in an inadequate storage facility, these treasures of unresearched primary documents remain out of reach for scholars eager to uncover their secrets.

Your contributions, whether in time or money, are vital to achieving our goal of preserving and digitizing these materials for educational and historical exploration. Join us in bringing these whispers from the past to the forefront of academic discovery!
