Route up Allsop PeaksWest side scree slope


West side scree slopeWest side scree slope

This route describes a hike to two of Utah's 12000 footers, North Allsop Peak (12625) and Allsop Peak (12606), located in the High Uintas Wilderness Area. Most of the route is easy, but there is a very steep section with loose rock where you climb 1400' in .4 miles. Even experienced hikers may not like this section. This is not a hike to do with a lot of people. You are in more danger from getting hit by someone else's flying rock than anything you could do to yourself.

Route Description

Burned section of  trailBurned section of trail

Start hiking south along the East Fork of the Bear River Trail. The first section of trail was burned out in 2002 and is in the recovery process. You will see lots of tall skinny burned aspens rising above a lush green carpet of grass and young bushy aspens. Grazing is allowed and you will most likely encounter a few cows near the start. The trail is easy to follow. At 3.7 miles you will reach a junction where the Left Hand Fork of the East Fork of the Bear River meets up with the Right Hand Fork. Turn left to take the Left Hand Fork. These first 3.7 miles are gently rolling and you will only gain a net 160 feet.

Shortly after the turn for the Left Hand Fork you will encounter two switchbacks as the trail climbs to bypass a waterfall. Follow the trail south about 4.1 miles from the split. In this section the trail climbs steadily but gently, and you will ascend 1120 feet. Along the way you will have views of Mount Beulah on your left and The Cathedral on your right.

Bottom half of scree slopeBottom half of scree slope up to the lip

At a convenient point, in the vicinity of N40 46.238 W110 41.793, leave the trail and head cross country .4 miles, gaining 600', to the base of the scree slope which is found at N40 46.103 W110 41.435. Climb 1400' up the scree slope to the saddle between North Allsop Peak and Allsop Peak. A distinct lip is reached at about 11600'. On the way down, you need to remember to bear left at this point because if you continue straight, your path will end in a 100' cliff.

Large blockLarge block

An interesting feature to note at 11760' is the large block sitting in the middle of the slope. It appears on the topo map as a very sudden jog to the west on the 11760 contour line just above the red route line.

As you proceed up the slope, note the rugged north wall and all the rocks waiting for the slightest excuse to fall.

Upper half of scree slopeUpper half of the scree slope

Initially, you will be walking along the base of a cliff to the south, but as you climb, it opens out and to the south (your right) will be a ledgy area. You may be tired of the scree by this point and be tempted to stray over that way but I wouldn't advise it because the ledges are loaded with loose rocks at head level just waiting to fall. If you are at the bottom of the couloir, at least anything you get moving will be at your feet.

Once you reach the saddle, it is an easy .5 mile walk gaining 226 feet along a wide, gentle ridge to Allsop Peak. From Allsop Peak you can see all the way to Kings Peak (13528), the highpoint of Utah, 16.4 miles to the east.

Lamotte and The CathedralLamotte and The Cathedral

Getting to North Allsop Peak is only slightly more difficult. The view from the saddle is of an imposing 50' cliff. However, it is easily skirted to the west. The summit is about .2 miles away and 245 feet up from the saddle. From N Allsop Peak you get great views of The Cathedral to the west, with Lamotte behind it. Beulah is to the north, and Tokewanna, NW Wasatch and Wasatch are to the northeast.

Time needed

This route can be done in a long day hike. It took me 11.5 hours, but up to an hour of this time was spent on a geocaching detour. There are 6 other peaks over 12000 feet in the area begging to be climbed, North Beulah (12140), Beulah (12557), Yard (12706), North Yard (12242), The Cathedral (12224), and North Cathedral(12283), so you might want to go for a multi-day trip and set up a base camp and climb several of them on the same trip.

Essential Gear

Nothing special is needed, but a GPSr is useful for finding the base of the scree slope.
