    Ten selected public-domain trail features form a connected Yost/Fern network: two shared features lead from the retained dataset entry to the branch, four continue to Fern Lake, and four continue to Yost Lake. The retained source-field distances do not fully agree with the separately published USFS hiking-guide distances.

    Ten selected public-domain trail features form a connected Yost/Fern network: two shared features lead from the retained dataset entry to the branch, four continue to Fern Lake, and four continue to Yost Lake. The retained source-field distances do not fully agree with the separately published USFS hiking-guide distances.
