I agree. The Mount Tallac Trail measured about the same as Katy's on the Mount Tallac Trail. We parked about 100 yards from the trailhead sign, and it was just about 5 miles to the top. I could be 4.9 to the top from the trail sign, but no shorter. It certainly isn't 4.3 miles. Also, the trailhead is at 6435 feet or so. Thus, it is 3300'+ to the summit.
