For Martin Luther King, Jr. weekend, I roamed the site of Camp A. E. Wood, where African-American troopers were stationed for the summers of 1899, 1903 and 1904. These Buffalo Soldiers patrolled Yosemite National Park from this base in Wawona. Among their many accomplishments was the 1904 establishment of what's believed to be the first formal interpretive facility in the entire national park system: the Yosemite Arboretum. Boundary changes the next year removed the Arboretum from Army stewardship and this promising start at educating and inspiring visitors was abandoned. Very faint remnants of the Buffalo Soldiers' interpretive work can still be discerned.
Here's another valuable interpretive effort from long ago: Yosemite Nature Notes, the precursor of this blog and of Steve's excellent video series. What creative efforts of ours will be abandoned or sustained for the next hundred years?
