Proposal Peak is a 13339feet mountain summit located in San Juan County, Colorado, United States.
Proposal Peak is situated five miles northeast of the town of Silverton on land administered by the Bureau of Land Management.[4] It is set seven miles west of the Continental Divide in the San Juan Mountains which are a subrange of the Rocky Mountains. Precipitation runoff from the mountain drains into tributaries of the Animas River. Topographic relief is significant as the summit rises 2700abbr=offNaNabbr=off above Cement Creek in 1.5 mile. The mountain's toponym has not been officially adopted by the United States Board on Geographic Names, however it is labeled as "13330" on USGS topographical maps, which corresponds to its elevation.[2]
According to the Köppen climate classification system, Proposal Peak is located in an alpine subarctic climate zone with long, cold, snowy winters, and cool to warm summers.[5] Due to its altitude, it receives precipitation all year, as snow in winter and as thunderstorms in summer, with a dry period in late spring. Hikers can expect afternoon rain, hail, and lightning from the seasonal monsoon in late July and August.
