Although generous in starting the park, the years of control by the GBGC left a mixed legacy. First, Schenck did not preserve the terrain in its approximate historical state, but beautified the landscape for a pleasing experience. Before the grounds were established as a military park, state historical societies began to erect monuments in the area purchased by the GBGC. Although well-meant, these monuments and interpretations were not based on researched evidence and were often constructed in convenient, if inaccurate, locations.
