Whatever contractor Mother Nature hired to ship the rough hewn granite to the Cathedral Range to build those superb mountains also mistakenly left a large load of this granite where Mount Clark now stands. It's that good.
An important factor to consider in making the Mono Meadows approach is the time of year to make the approach. Earlier in the summer, the boggy conditions on the approach shortly after leaving Illiouette Creek can make for slow going and buggy conditions. Later in the year, the progress is easier but the high camp below Clark's sweeping western face is dry so plan accordingly.
From the camp beneath the west face, head up and right through a whitebark pine forest, eventually turning north, heading up easy sandy slopes. At about 11,000 feet, the Secor guide describes a gap in the arete. Perhaps a better way to characterize it is a gap/low point in the ridge as the ridge to the south heading towards Gray Peak isn't much of an arete.
At this gap, there are two ways to proceed. One is to downclimb from the gap (Class 2ish) and turn north on sandy slopes to heading toward the summit. Eventually, after passing a few prominent towers, you will scramble back up to the ridge.
Another more fun option is to simply start climbing the Class 3-4 rock right from the gap. After a few fun pitches, including an easy knife edge, descend north along a 3rd class ledge after reaching an impassable barrier. Shortly after descending, climb back up onto the crest of the ridge.
After regaining the ridge, enjoy more easy climbing on golden granite until reaching King's awkward step-across. After an easy but probably ungraceful move, make the step across and follow a steepish but solid Class 4 pitch to the summit. The summit is a short scramble above.
A good argument can be made that more granite domes, spires, ridges, and faces can be seen in the sweeping view from the summit than anywhere else in Yosemite or the High Sierra.
