Carpenter Summit is a highway pass name approved through the United States Geological Survey. This pass was created during the construction of I-8 from 1972 to 1974 in this area, but was never named unlike the three other 4,000 feet (1,200 m) then named during construction.[1] The name “Carpenter Summit” was proposed in late 2019 then submitted and as of October 2020 pending the various levels of place name acceptance.
This highway pass is the first of four which were completed through the Cuyamaca Mountains of southeastern San Diego County, California and traversed by Interstate 8 East bound at an altitude of 4,052 feet (1,235 m) and West bound at 4,078 feet (1,243 m). The freeway is divided at this location by an east–west ridge with a peak of 4,120 feet (1,260 m).
