Table Mountain (Great Western Divide), Sequoia & Kings Canyon NP, California is added to the nominations. Looks like a hike promoting less of "giggles" and more of the noun preceding it according to Bob Burd's trip report (Laura was part of that hike).

The hike, both trail and a route, starts and finishes at Shepherd Pass Trailhead. Although a very tough hike, the trip report covers events within a calendar day, so, ergo, it's a day hike!

I noted in Wikipedia that THIS Table Mountain is the highest of 21 Table Mountains in California. (Challenge for someone --do all 21!)
