Silver Strand Falls drops 574 feet (175m) along Meadow Brook, at the western end of Yosemite Valley, within Yosemite National Park. The falls are commonly thought to drop 1170 feet (356m), this is incorrect. The name Widow's Tears had been applied to Silver Strand Falls in the past, but the lower-volume waterfall located one drainage to the east of Meadow Brook, is now known as Widow's Tears, and is thought to drop 1,170 feet (360 m), hence the confusion regarding the height.
Note that the recent 1:24,000 topo map of Yosemite Valley shows the height of this waterfall as 400 feet (120 m), not 574 feet (175 m), which is derived, apparently, from ice climbers. Since the waterfall is not vertical, it is possible that the ice-climbing height is, in fact, 574 feet (175 m), while the difference in elevation between the top and bottom is as shown on the topo sheet at 400 feet (120 m).
