which is a 2 mile hike from Mather Lodge, considered moderate to strenuous. Had my entire /PM gear with me, including reserve battery, charge controller, mini-chair, water, CW straight key, you name it. Hefty package all in all... The waterfall was great, we had a great hike, was warm to hot and humid. Sure sweated a lot, but had great fun hiking. Did not operate at all, since I would have had to string up a 40m antenna and today was really reserved for family. But - was a great RaDAR exercise to get into shape for the contests.
More details on my pack to follow another day.
