10. Hike to South Thunder Mountain
The summit of South Thunder Mountain, sitting at 11,154 ft, is a superb peak. Located on the Alpine Ridge of the Wasatch Mountains, this peak is criminally overlooked.
The Schoolhouse Springs trailhead leads you onto an old dirt road, that switchbacks for about 2 miles through the foothills, before reaching a small meadow. The trail then turns into a single track. Continue for another ¾ to 1 mile until you reach the Second Hamongog Trail, found in a second meadow, at about 8,000 feet.
From the Second Hamongog Trail, follow signs towards Lake Hardy. As you go along, the views of Lone Peak and Bighorn Peak just get better. For the next 1,400 feet of elevation you will be hiking through rather steep terrain, but with switchbacks.
Eventually you will reach a ridge and large boulder (9,400 ft). From this ridge, you can see eastward towards Box Elder and Timpanogos. Next head north along the ridge, following the trail. At around 9,600 ft you will find a small flat spot, where you will begin dropping down into the Lake Hardy basin, to the northeast. The terrain will becoming increasingly flat, you will go up and down for about 1.5 miles. There is no trail to follow, but as long as you continue north, you can’t really go wrong (GPS navigation is recommended, as is scoping the area on Google Earth, ahead of time).
