I'm sorry you found the High Trail between the Triple Peak Fork and the Lyell Fork to be boring. If you had more time, a really scenic cross-country alternative goes up that first creeklet you hit going north on the High Trail. After a short distance in open forest, you emerge on open alpine meadows and slabs for easy class 1 hiking for several miles north, passing small lakes tucked under Isberg Peak and Long Mountain (camping available), until you reach Harriet Lake in its completely open above-timberline basin. Oh, and you have constant views of the Clark and Cathedral Ranges the whole way. Then you follow Harriet Lake's outlet stream down to Foerster Creek and from there contour/angle up to "Foerster Lake" (unnamed on the topo) and then over to pick up the High Trail again. I've hiked all over the Yosemite backcountry and I think this is one of the prettiest areas. I've never seen anyone else in this area during the three times I have visited it over the years.
I hope you have time to visit this area again. Come in from the Granite Creek area on the Sierra National Forest and you can get to Sadler Lake in one day, and then over Isberg Pass to the high meadows I described above the next day. The Isberg Pass region is also very scenic.
The meadow along Foerster Creek is quite pretty, Harriet Lake Basin had an outstanding wildflower displays, the best I have seen in 3 visits to this area, just outstanding. The lake in the middle of the crosshairs is very pretty with outstanding views towards the Clark Range, good sunrise photography, also good sunset photo opps from the western end of the lake looking back towards the ridgeline.
Also there looks like a shortcut across the ridge to the Sadler Lake region, class 2 on both sides, little easier from the south, we did not do this route because Lisa was worried that we would miss Jim. The Isberg Trail is way to long and windy, we did a short cut, a class 2 ascent on the northern side to reach the pass and also used a granite ramp south of the trail to cut down on all the unnecessary switchbacks.
Pass on ridgeline to access Sadler in crosshairs, will use this route in and out the next time:
