Dog Lake & Lake Desolation

Another easy to moderate hike up Big Cottonwood Canyon is the Mill D North Fork trail to Dog Lake and Lake Desolation.  This is a popular area for mountain bikers, particularly on the even-numbered calendar days, so keep an eye out for them and be considerate.  Weekdays are generally less crowded than the weekends to hike on the trail.  During the winter months, it is not unusual to see snowshoeing and cross-country skiing in the area.  Dog Lake and Lake Desolation are approximately 2.5 miles hiking distance from each other, and can be hiked within the same trip given sufficient time.

The trailhead at Mill D North Fork is reached from the Salt Lake Valley by taking the 6200 South (Exit 6) off of I-215 and turning right (at the light) onto Wasatch Boulevard (SR 190).  At Fort Union Boulevard (7200 South), turn left (east) to go up Big Cottonwood Canyon towards the Brighton and Solitude Ski Resorts.  Continue driving for approximately 9.0 miles up the canyon to the Mill D North Fork turn-out area located left (north) of the highway across from the Jordan Pines turn-off.  The trail ascends Reynolds Gulch very briefly before veering to the right (eastward) to curve around the mountain towards Mill D North Fork Canyon.  Resort homes will appear across the stream near the mouth of the canyon while approaching it.  In the canyon beyond the resort home area, the trail reaches the Mill D North Fork streambed, which varies in water flow depending on the season.  After approximately 1.7 miles the trail splits; the left trail going to Dog Lake (another 0.6 miles) while the right trail goes to Lake Desolation (another 1.9 miles).  A spring lies downhill from the point where the trail splits.

The trail to Dog Lake ascends a moderately steep drainage that levels out some just before reaching the lake at approximately 8,735 feet elevation.  Unlike most surrounding lakes in the Wasatch Range, Dog Lake lies in the midst of a forest instead of a cirque.  While dogs are permitted at this lake, they can only be brought in from the Mill Creek side.  No dogs are allowed in Big Cottonwood Canyon due to the area being a vital watershed for the Salt Lake Valley.  Anyone caught with a dog beyond the warning signs near the south perimeter of Dog Lake could face a hefty fine.  Distance from the Mill D North Fork trailhead to Dog Lake is approximately 2.3 miles one-way with an elevation gain of approximately 1,450 feet.

Continuing along the trail to Lake Desolation (or Desolation Lake to some), the route makes a moderately steep climb northward and then levels out some after veering in more of an easterly direction.  Occasional meadows appear along this stretch and the surrounding peaks become more visible the closer you get to Lake Desolation.  A final climb comes about 0.5 miles before the lake while ascending the northwest rim of the basin where the lake lies.  The trail continues beyond Lake Desolation to join with the Great Western Trail, which provide spectacular views of the surrounding landscape.  From the northwest rim, a descent of about 50 feet is made to reach the shore of the lake at approximately 9,200 feet elevation.  Distance from the Mill D North Fork trailhead to Lake Desolation is approximately 3.6 miles one-way with an elevation gain of a little less than 2,000 feet.
