John Muir was a naturalist, writer, explorer, and early national parks advocate. Although known as a man of the mountains, John Muir also was a shrewd businessman, dependant on expansion of urban fruit markets to feed his family and fund his conservation advocacy. The intent of this thesis is to present a model of interpretation of John Muirs life and legacy via cultural landscapes. The scope of the study concerns the two sites most directly connected with Muir: Yosemite National Park and the John Muir National Historic Site. Archival research, site visits, and interviews conclude with recommendations and a feasibility analysis.
