The Leuthhold Couloir is located on the West Face of Mount Hood. This is a high quality intermediate route with steep snow climbing. The route crosses over the Reid Glacier making both crevasse rescue and ice axe skills mandatory. The views on the Leuthhold are quite good including Illumination Rock, the Reid Headwall, Yucum Ridge, Crater Rock, the Hogsback and more.

View Google Maps Directions here. [63 Miles | 1 Hour & 27 Minutes] Getting There from Portland: From I-5 take exit onto I-84 east for 12.8 miles. Take a right at exit 16 onto 238th Dr. Continue on NE 242nd Dr (road changes name). At about 3.4 miles from I-84 turn left onto E Powell Boulevard. This road turns into US-26 E/Mt Hood Hwy. In 38.9 miles turn left onto Timberline Highway. This will take you all the way to the Timber Lodge parking lot (end of the road) which is the starting spot for this route.
From Timber Lodge Parking lot head over towards the Timber Lodge. At the lodge head north towards Mount Hood. Depending on the time of year you may see ski trails. If they exist, go to the right of them where a climber trail should appear. This is to avoid climbers walking along the ski runs when it's in season. But if the lifts aren't open, follow the lifts. After about 2 miles you arrive at the top of the ski lifts at about 8,500 feet in elevation.
Once past the ski lifts, start making an upward traverse towards Illumination Saddle (north, lightly west). Crossing the Triangle Moraine is pretty straight forward and easy.
At Illumination Saddle rope up for the Reid Glacier. Descend a small distance to make traveling to the Leuthold Couloir easier. Traverse directly north toward Yucum Ridge but not quite going to the ridge. Along the way you pass the Reid Glacier Headwall.
This traverse can be quite steep depending on the snow conditions that year. Above are several tempting couloirs. They are steeper than Leuthold, and some end up among the castle crags, which is difficult.
Keep traversing until the last big coulior before Yocum Ridge. Right away the coulior narrows and steepens. This is the hourglass, and the most likely place to get nailed by rockfall. Sprint through this short section. The slope is less steep, and the couloir widens after the hourglass is passed.
From here, stay in the biggest coulior, DO NOT TURN LEFT. You'll end up in a dead end coulior on Yocum Ridge. The coulior ends at a shoulder, and you're on the summit ridge. Turn right, and follow the ridge to the summit. The ridge has nice exposure, but isn't too narrow.
Once on the summit, descend the standard south side route.

Here is a list of pretty much everything that you will want/need for this climb.
I suppose it may be possible during very icy conditions to need a few ice screws. But typically folks don't bring them for this route. An ice tool however may come in handy during the winter months. I know I was very happy to have brought it.
