daveDavid Martin


David O. Martin is President of the Three Eagle Foundation, Inc. Dave retired to the Muscoda area following a career in both the public and private sectors. Dave was a state legislator from the Fox Valley in the 1960’s and early 1970’s during the exciting time of bipartisan cooperation to move Wisconsin forward. During that time, he was involved in many environmental and educational legislative initiatives, including authoring Wisconsin’s Wild Rivers legislation in 1965.

Dave became good friends with Frank Shadewald after moving to the river valley. They were neighbors living on the same dead end road (Effigy Mounds Lane) on the river in Richland County and shared common life experiences, such as serving in the US Army Corps of Engineers during the Korean Conflict era. Frank also brought Dave into his world and work with the effigy mounds of the area and his interaction and friendships with people of the Ho-Chunk Nation and other Native American cultures. Dave and his wife, Joan, spent time with Frank on Frank’s Hill learning about Frank’s theories related to the effigy mound builders, the calendar mounds and other stories about the site.

Dave has served as Trustee of the Frank Shadewald estate and succeeded Frank as head of the Three Eagles Foundation, which Frank established before his untimely passing. He remains committed to fulfilling Frank’s vision for preserving the site and using the land for education and sharing with people of all beliefs who wish to visit Frank’s Hill.
