According to one source (William Hill, p. 214), the road over Rock Springs Pass was a summer shortcut. Winters, the route ran around the south of the Antelope Mountains. According to Richard Burton (quoted in Hill, p. 213), “Beyond Antelope Springs was Shell Creek, distant thirty miles by long road and eighteen by short cut.”
A detour along this route would continue southeast on White Pine County Road 32 to Twelvemile Summit, then turn northwest over Tippett Pass on White Pine County Road 34 to Hwy 893 (White Pine County Road 31) and rejoin the route at the site of Spring Valley Station.
Note: water is marked as available at Rock Springs on the summer route. No water sources are marked on the alternate.
