Old Hyndman Peak, Mountain summit in Pioneer Mountains, Idaho, US

Old Hyndman Peak is a mountain summit in the Pioneer Mountains reaching approximately 11,775 feet with multiple climbing routes that vary in difficulty. The paths cross through steep rock sections and loose talus fields that require careful foot placement and stamina.

The mountain was named after John Hyndman, an early explorer who helped map the Pioneer Mountains region in Idaho. His work contributed to documenting this remote area of the American West.
