From Black Rock Desert Nevada wiki
Highway 48 passes through the former Sahwave Naval Gunnery Range.
- Nevada tourist highway map (1955?) shows the Black Rock Desert as a "Danger Area." The Sahwave is not named, but labelled as "Travel Restricted" and "Danger Area". Highway 48 through Vernon travels through the "Danger Area".
- Peggy Trego, "Highway 48 Remains Open For Travel, Long May it Waver: It takes you from Lovelock to Black Rock," Nevada State Journal, March 29, 1956. The 1956 Nevada Highways map showed highway 48 as restricted.
- Official highway map of Nevada (1963-1964) does not show the Black Rock Desert as restricted. However, the unnamed Sahwave is marked as "Danger Area" and "Travel Restricted" on 48.
- Official highway map of Nevada (1965-1966) shows no restrictions in either the Black Rock Desert nor Sahwave.
