Jumbo Mountain (Second Attempt) - Standard Route
In Darrington, find Darrington Street in the south blocks of town. Follow this road until it turns to gravel, then follow up until you do the S switchbacks (two turnpins). Continue on the road until it ends at a small parking area. An Oct. 2016 road washout has made the hike 10 minutes longer.
I have not finished climbing this route but I know the lower area well. Trip reports for this mountain and route are horrible, so hopefully I can clarify this lower section until I return to finish. I have made 3 attempts.
Road Access: Fair gravel road
Route (print all this below and take with you)
Follow the road, then the trail for about 1.2 miles to a prominent creek bed with a large, exposed culvert. This stream is the main stream to follow. In theory, just follow this stream to the summit area. BUT, there is a trail you can take for a good distance avoiding the brush of the lower elevation portion of the stream. The catch is not following this trail too far up. The trail has sucked many climbers way to high. The higher you go, the more false drainages you place between you and the correct route.
Finding The Climbers Trail (The first 100 yards)
From the creek, go back about 200 feet and enter the woods into the most conifer looking area (basically avoiding the deciduous edge of the creek chocked full of brush). Look for some ragged old pink flagging. The goal here is to go several hundred feet through a low incline forest to find the trail where the hill gets steep. Just before it does get steep, look for two huge cedar trees with bases well above ground level. The trail veers sharply left (north) from these trees. After a short patch of blowdown hiding the trail, the hillside becomes steep and the trail appears.
On the Climbers Trail (print this and take with you)
The forests are fairly open on the steep hill slope so you could do without the trail but you will save energy using the trail. It switchbacks uphill but never crosses a smaller wooded creek draw to your left. To your right, as you are climbing, at times you will sense a valley to your right. This is the key drainage you want but it appears to drop a long way down, like a deep valley. The trail never really drops into this drainage although many reports will suggest it does. At about 2,300 feet of elevation, there is a trail split that is almost un-noticeable. (There will be a rock on the left side of the trail with half the moss removed). The faint right fork will take you right to the edge of the forest where you will be on an edge (around 2,425 feet). Keep scrambling up the forested edge of the ravine until there is an opening from a small slide. I placed 3 bands of orange ribbon (in 2016) around a tree where you can drop down into the canyon. In reality, the drop is only about 100 feet but you can't tell from above due to leafy trees (in winter, you can see down). You may hear the water down below. Once you reach the bottom, their is a nice open creek gully to follow. Hike up it a few hundred feet to where the drainage splits at 2,600 feet (see image 1). A smaller gully comes down from your left, it is a bit narrower, brushier and steeper than the one you are in. Follow this left open gully for 300 hundred feet (at about 2,900 feet) until you see a trail cutting to the right going into some timber. This trail takes you out of the drainage and now you are now between the two rock filled drainages. This trail starts out well defined, climbing steeply up the timber until you hit an area with tons of deadfall from an avalanche. Keep a gradual traversing climb up through the debres. The tread is below all the fallen trees. About halfway through the avalanche killed trees, keep your traversing and look ahead for the oldest, tallest and thickest old-growth Douglas-fir tree. Go to that tree to pick up the faint tread again. The next section is likely to have no trail but the route keeps the steady climb but traverses below a huge field of vine-maple. A deep ravine of the main creek will keep you from dropping to far down on your right and the thicket of vine maple will keep you from climbing to high on your left. Once around the vine-maple, a narrow forested rib of trees is found with tread. This will dump you right into the next major rocky drainage gully around 3,600 feet, where you will gain a large amount of elevation. This rocky drainage can get steep in places and when flowing with water, could force you to go around into some terrible steep brush climbing. But the upper parts of the gully are good and you climb up until it terminates against a cliff face at about 4,300 feet. Now traverse easily right about a quarter mile in open more alpine terrain to the crux gulley at 4,500 feet that grants access to the upper bowl of the mountain. The short steep section in the gulley is class 4. Some have used a rope to prevent slipping and falling into the creek. Early season snow makes this last gulley an easy snow climb up. Once above, the upper basin is easy travel to the base of the summit. (More on that when I get there in 2017).
(Image 1) Take this smaller gully coming down from your left, it is a bit narrower, brushier and steeper than the one you are in. At 2,600 feet.
The edge of the forest at around 2,425 feet. Drop down here into this canyon. An easy to miss side trail takes you over to the edge from the main trail (look for rock with half the moss gone).

This is the rock gully that takes you from 3,600 to 4,300 feet. At the top is the headwall that you start the quarter-mile traverse in open terrain.
