About the Trust


The Keystone Marker Trust is dedicated to preserving, interpreting, and re-creating these proud symbols of our past as a way of orienting our Commonwealth—literally and philosophically—toward a better future. Restored and re-placed markers speak to the vibrancy of our communities. We intend for keystonemarkertrust.org to be a resource for organizations, individuals, and municipalities to showcase their historic preservation, community development, and learning/teaching achievements–achievements of which the markers are part and parcel.

Download our current informational flyer here.  The Keystone Marker Trust has the following priorities for the near future:

  1. Create new patterns to allow towns, historical societies, etc., to replicate their historical marker signs and poles
    • Most towns had at least 4 historically; rivers, borough lines, creeks, trails, and distances also used keystone markers
    • This will require re-designing the historic poles to meet current PennDOT standards
  2. Work with PennDOT to establish a uniform set of principles about what markers can be grandfathered in to current safety standards as well as guidelines for marker care.
  3. Create an Adopt-a-Marker Educational tool kit to enable schools to build local and state history programs around a marker
  4. Continue to build the interactive on-line database of all current and historic Keystone Markers
  5. Create a revolving loan and small grant fund to assist municipalities and interested organizations in replicating and restoring their markers
  6. Work with Wayfinding groups to integrate the markers into their activities. Will enable geo-coordinates to be correlated to markers.
  7. Work with municipalities, historical societies, civic improvement groups, and historic preservation groups to utilize www.keystonemarkertrust.org as a way to highlight their special places and preservation/community development initiatives

Mike Natale was born and raised in the New Jersey suburbs of New York City. Childhood vacations in the family RV took him all over the country and inculcated an early love of the open road. The joys of travel mixed well with a love of history, and Mike became a dedicated highway archaeologist and “roadgeek” by the time he had entered high school, dragging parents and friends to places like the abandonded Pennsylvania Turnpike alignment and bypassed stretches of the Lincoln Highway. It was college at Carnegie Mellon University that got Mike out to Pittsburgh originally, and falling in love with the city was what has kept him there for the last 16 years. After graduating with a BA in History, Mike spent a few years working for the national office of his college fraternity (Kappa Delta Rho) doing non-profit and educational work. Although history remains a passion and he volunteers with the Senator John Heinz History Center in Pittsburgh, Mike took quite a different path for a career and became a local police officer. With whatever free time he has, Mike still travels every chance he gets, and is attempting to visit every county in the United States and every township and borough in Pennsylvania, a goal which takes him past Keystone Markers on a regular basis.
