Stanford Point
Seeing Bridalveil Fall from Stanford Point will be one of the highlights of your day. If you're equipped with a camera, however, you're likely to get the peculiar impression that the trees just west of Bridalveil, which will be partially obscuring the fall, are talking to you. "Just a few steps to the left," they'll be saying, "and we'll be out of your way."
Like the sirens of antiquity, they are not to be trusted. You can edge about as far over as this shot's viewpoint, but any farther and you will, like so many Greek sailors before you, be battered upon an unforgiving set of rocks. Have a look over the precipice here through your telephoto lens and you're likely to see a great tangle of camera gear and human bones.
Stanford Point isn't the only place this happens - check out Illilouette Falls sometime, for example. It will soon become clear to the careful observer that, just as squirrels eat nuts and mountain lions eat deer, Yosemite feeds on photographers. So keep your wits about you and stay safe in the woods.
