Acne is a common skin disease that causes pimples. Pimples form when hair follicles under your skin clog up. Most pimples form on the face, neck, back, chest, and shoulders. Anyone can get acne, but it is common in teenagers and young adults.
Horsetail Falls â Considered to be the epitome of the horsetail form by the World Waterfall Database, Oregon's own Horsetail Falls is a must-see on any Columbia River Gorge trip, found along the Historic Columbia River Highway just east of the Oneonta Tunnel.
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.
