North from Wiseman the Dalton skirts the east edge of Gates of the Arctic National Park. Dall sheep are often visible on the mountain slopes, and the scenery goes into overdrive. By Mile 194 the first views appear of the massive wall of Sukakpak Mountain (4459ft) looming dead ahead. Just before Mile 204 is a lookout with a half-mile trail to Sukakpak's face, while soon after, even taller promontories arise - imposing black talus cones, 7000ft high, riven by glacier-carved valleys.
