Sayres Benchmark is a {{convert|13746|ft|meter|adj=mid|-elevation|abbr=off|sp=us}} mountain summit in Chaffee County, Colorado, United States.

Description

Sayres Benchmark is located {{convert|3|mi|km|spell=in}} east of the Continental Divide in the Collegiate Peaks which are a subset of the Sawatch Range. The mountain is set on the boundary of the Collegiate Peaks Wilderness on land managed by San Isabel National Forest. The highest peak in Colorado and the Rocky Mountains, Mount Elbert, is {{convert|7.46|mi|km}} north-northeast of Sayres Benchmark, and the fifth-highest, La Plata Peak, is less than two miles to the northeast. Sayres ranks as the 130th-highest summit in Colorado. Precipitation runoff from the mountain's south slope drains into Clear Creek, whereas the north slope drains to Lake Creek, and both are tributaries of the Arkansas River. Topographic relief is significant as the summit rises {{convert|2950|ft|0}} above North Fork Clear Creek in {{convert|1.5|mi|km}}. An ascent of Sayres involves 10 miles of hiking with 3,500-feet of elevation gain.Mike Garratt, Bob Martin (1984), Colorado's High Thirteeners, Johnson Books, {{ISBN|9780917895395}}, p. 39. In winter the peak offers excellent ski mountaineering on its rugged north face.Ben Conners, Brian Miller, Climbing and Skiing Colorado's Mountains: Over 50 Select Ski Descents, Rowman & Littlefield (2020), {{ISBN|9781493046737}}, p. 175.
