Mapping California's Golden Trout in the Heart of the Sierra Nevada Mountains

Detailed map of exhibiting the route of the scientific party led by Barton Warren Evermann to determine the habitat extent of the Golden Trout, based upon an earlier map by Joseph Le Conte, an early member of the Sierra Club in the 19th Century, who created an important map of the region.

At the beginning of the 20th Century, there was significant concern about the risk of extinction of Californa's Golden Trout.  The issue was even raised with President Theodore Roosevelt, an ardent conservationist in his time.  As a result of the President's concerns, the US Bureau of Fisheries commissioned a study of the issue by Barton Warren Evermann.  Barton Warren Evermann (1853-1932) was an American ichthyologist.   

The map shows the "Route of travel in the Golden Trout Investigation in 1904" via dash line. The map shows much of the Kern River watershed. Shows Visalia, Exeter and King's River at the extreme left and Mt. Whitney and Lake Owen in the east.

The map is filled with details and it locates all tributaries, mountain peaks, mills, camps, settlments and post offices. At center is the "Giant Forest" of the Sequoia and the Sequoia National Park.  

Joseph Le Conte

Joseph LeConte was an early member of the Sierra Club and served on its board of directors from 1892-1898. After his sudden death in Yosemite on the eve of the first Sierra Club High Trip in 1901, the Club chose to remember him by building LeConte Memorial Lodge. His son, Joseph Nisbet LeConte (“Little Joe”), succeeded him as a board member, served as president of the Sierra Club for two years (following the death of John Muir in 1914), and remained a board member until 1940.
