Argentine Pass
mountain pass in Colorado, USA
Argentine Pass, elevation 13,207 ft (4,025 m), is a high mountain pass that crosses the Continental Divide in the Front Range of the Rocky Mountains of central Colorado in the United States. Argentine Pass is located on the crest of the Front Range along the boundary southwest of Georgetown and is the highest named vehicle-accessible pass in the state.
Some early references use other names for the pass. An 1867 description of the trip from Georgetown into the valley of the Snake River refers to it as Sanderson Pass. A lithograph caption from 1869 calls it the Snake River Pass.
Geography
Argentine Pass is 0.94 miles (1.51 km) north of Argentine Peak and 0.95 miles (1.53 km) southwest of Mount Edwards. To the east is the valley of Leavenworth Creek, a tributary that joins the South Clear Creek south of Georgetown. To the west is the Horseshoe Basin, a deep glacial cirque at the head of the Peru Creek, a tributary that joins the Snake River just north of Montezuma.
The continental divide at Argentine Pass serves as the boundary between Clear Creek and Summit counties.
The pass was formerly used by a toll road and stagecoach route.

Why this record matters
The subject matters to the places & architecture register because the source frames it as mountain pass in Colorado, USA. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The strongest evidence will usually combine a dated visual record with documents produced by the authority responsible for the place. The source revision retrieved here is dated Aug 19, 2026. The linked authority identifier is Q4789420. Authority coordinates are 39.625, -105.783. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1867 and 1869.
Architectural summaries often privilege surviving fabric and can understate demolished phases, contested use or displaced communities. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
