Photo Album

Hike to a concrete arrow on a hill south of the Mogul area of Reno, built as part of a navigation guide system for early U.S. Airmail pilots used in the 1920s and 1930s. The hiking route starts from the open space access point at Damselfly Drive & Riverflow Drive, follows single-track up to the Steamboat Ditch trail, takes the ditch trail to the Hole-in-the-Wall tunnel, then follows the pre-tunnel ditch route and uphill to the arrow. Found through this recent RGJ article.
