Greenhalgh Mountain is a {{convert|13220|ft|meter|adj=mid|-elevation|abbr=off|sp=us}} mountain summit in San Juan County, Colorado, United States.

Description

Greenhalgh Mountain is located {{convert|9|mi|km|spell=in}} east-southeast of the community of Silverton, on land managed by Rio Grande National Forest. It is situated less than {{convert|3|mi|km|spell=in}} east of the Continental Divide in the San Juan Mountains which are a subrange of the Rocky Mountains. Precipitation runoff from the mountain's slopes drains into tributaries of the Rio Grande and topographic relief is modest as the summit rises {{convert|2400|ft|m|abbr=off|sp=us}} above the river in 1.25 mile (2 km). Neighbors include Sheep Mountain, {{convert|0.79|mi|km}} to the west and Canby Mountain, {{convert|2.49|mi|km}} to the northwest. The mountain's toponym has been officially adopted by the United States Board on Geographic Names, and was recorded in publications as early as 1906.Henry Gannett, United States Geological Survey (1906), A Gazetteer of Colorado, US Government Printing Office, p. 80.
