Sacajawea Peak is an mountain summit in Custer County, Idaho, United States.
Sacajawea Peak ranks as the 13th-highest peak in Idaho and is located on the crest of the Lost River Range which is a subrange of the Rocky Mountains. The mountain is set on land managed by SalmonâÂÂChallis National Forest. Neighbors include Mount Idaho 1.16 mile south and Borah Peak, the highest peak in Idaho, is one mile to the north. Precipitation runoff from the mountain's west slopes drains to Big Lost River, whereas the east slopes drain to the Pahsimeroi River. Topographic relief is significant as the summit rises above Thousand Springs Valley in 4.5 miles (7.2 km) and the north face rises in 0.35 mile (0.56 km). This landform's unofficial toponym honors Sacagawea, the most frequently honored woman in the United States with four mountain peaks and one glacier named for her, and at least 16 statues created in tribute to her.
Based on the Köppen climate classification, Sacajawea Peak is located in an alpine subarctic climate zone with long, cold, snowy winters, and cool to warm summers. Winter temperatures can drop below âÂÂ10 ðF with wind chill factors below âÂÂ30 ðF.
