California Trail leaves this broad valley through a narrow and rugged pass.
The emigrants heading west probably fanned out crossing this basin and converged again at
Pinnacle Pass, a gap in the rocks. They often did not cross in single file lines, fanning out
helped to avoid dust from those ahead. Nor would many emigrants be riding in the wagons,
most would have walked.
Pinnacle Pass provided the westbound exit from City of Rocks. More than one traveler
described the pass as narrow and rugged. In later years teamsters used cables to cable heavy
freight wagons down the far side. Pinnacle Pass was rugged enough that twentieth-century
road builders avoided it by dynamiting an easier route further to the right for the present
day road.
July 7th  –  we came six miles to where the Salt Lake Road comes in, five miles farther to a creek in a valley
where we nooned. We traveled twelve miles to Goose River and camped. Good water and grass, sage and
willow wood, distance twenty-three miles. This forenoon we had fine roads, but this afternoon they were as
bad as we have ever passed over, some places very sidling, and great danger of turning over. I saw a company
today that came by the Salt Lake Road and they said they had to ferry Green River once, Bear River twice and
Weber River twice. That makes five times they ferried, and four days they traveled over the worst road that a
wagon ever ran over. They reached the fork of the road, with horse teams, four days before we got there, and
we beat them to where the roads come together. I make it three hundred eighty miles by Fort Hall, and the
Mormon guide makes it three hundred eighty-five miles by the Salt Lake Road. All well, teams are fine and
travel well. This is a cool day.  I wore my overcoat.
