Mount Heyburn, Mountain summit in Sawtooth Range, Idaho, US
Mount Heyburn is a mountain summit in the Sawtooth Range that rises to 10,229 feet with two distinct peaks. The mountain frames the southwestern end of Redfish Lake, sitting within a recreation area known for outdoor activities.
The first recorded ascent took place in 1935 when Robert and Merriam Underhill climbed the mountain with Dave Williams using the Southwest Ridge route. The peak was named after Weldon Heyburn, an Idaho Senator who served in Congress during the early 1900s.
The mountain received its name from Weldon Heyburn, who served as an Idaho Senator in the United States Congress from 1903 to 1912.
Climbers reach this summit by starting at Redfish Lake and following either the Bench Lake Trail or the Redfish Lake Creek Trail to establish a base camp. Weather and snow conditions vary greatly by season, so visiting during warmer months offers safer and more accessible routes.
The Stur Chimney route stands out as a notable climbing feature that requires climbers to navigate overhanging stone formations on Grade II, 5.4 rated granite terrain. This specialized passage offers rock climbing elements that differ markedly from straightforward summit hikes.
