This summit is part of a two-vehicle shuttle description that includes UN13,540 B; UN13,312 and Gudy Peak. Mileage from Cinnamon Pass to UN13,403 is about 2.25 with 1,000 feet of elevation gain. If completing the entire circuit, total mileage will be 8.5 and total elevation gained will be 3,050 ft.
From the parking area near the top of Cinnamon Pass, stroll across tundra NNE toward Pt.13,112. Contour around the point a little below the 13,000 foot level, then contour across the head of Cleveland Gulch. You will encounter some rocky gullies soon after rounding below the point. It is best to stay high and above the head of these gullies. Passing both through rubble, talus and tundra, skirt below the summit of UN13,250 on the south slopes and you should be able to pick up an old mining road that will lead up to the saddle between UN13,250 and UN13,403. Continue east on mostly tundra to the summit of UN13,403. One summit down.
Bonus Points: On your way over to UN13,403, climb the SE ridge of Wood Mountain to its summit, if you have not already climbed this bicentennial peak. However, we include Wood with a circuit hike of Wood, Gravel, unranked 13,708 and ranked 13,722 - all bicentennial summits.
