This summit off of Highway 20 offers gorgeous views of the craggy North Cascades and a great workout.
From the East Bank Trailhead head down the trail to a crossing of Ruby Creek. Popular in the gold rush, it is still possible to see a few signs of gold mining activities today. Interpretive plaques are near the bridge, and some sites are still visible.
Cross Ruby Creek on a bridge, and come to a junction with the Canyon Creek Trail. Here, stay left to stay on the East Bank Trail. 2.8 miles from the trailhead there is another junction. A short spur trail heads west here to Ross Lake and campsites, while the steep Little Jack Mountain Trail heads northeast.
Hop on the trail up Little Jack Mountain and start switchbacking steadily. It's a long, 4-mile, unrelenting ascent, but as you climb, views improve and you're rewarded at the top with a really stunning panorama.
