This Yellowstone National Park Hiking Medallion features a likeness of a geyser and a buffalo, both of which you are likely to encounter within Yellowstone National Park. Hiking Medallions are increasingly popular in the United States and have been a long standing tradition in Europe. These medallions may be gently shaped to fit on hiking staffs, paddles, etc. Pre-drilling holes for the included nails is recommended to affix your medallion. They can also be flattened and glued to RV's and other flat surfaces.
