In physics, the wavelength of a sinusoidal wave is the spatial period of the waveâthe distance over which the wave's shape repeats, and the inverse of the spatial frequency.
The original âCave of the Windsâ was a cavern located behind the Bridal Veil Falls. The Bridal Veil Falls is the smaller waterfall located between Luna Island and Goat Island, beside the American Falls. The Cave of the Winds was an overhanging ledge, consisting of Lockport Dolostone rock, at the top portion of the gorge where the waters of the Bridal Veil Falls flowed over. Originally this portion projected more than 30.5 metres. Due to this overhang of rock, a cavern behind the cascading water was formed.
Located 27 miles (43 km) east of Portland just off Interstate 84, the misty, white Bridal Veil Falls consists of a pair of quick cascades that are well worth the short but steep half-mile hike to the viewing platform. An upper trail also leads to cliffs that reveal great views of the Columbia River Gorge. Proceed another mile (1.6 km) east on the Historic Columbia River Highway. Also accessible via Exit 28 from I-84. Multnomah Falls, 30 miles east of Portland, is Oregonâs tallest waterfall.
