The Wiggle is a one-mile, zig-zagging bicycle route from Market Street to Golden Gate Park in San Francisco, California, that minimizes hilly inclines for bicycle riders. Rising , The Wiggle inclines average 3% and never exceed 6%. The path generally follows the historical route of the long since paved-over Sans Souci Valley watercourse, winding through the Lower Haight neighborhood toward the Panhandle section of Golden Gate Park.〔( In 1994 Tubular Times (1994) printed an article on The Wiggle )〕 The lower end of the route begins at either end of the Duboce Bikeway in the block of Duboce Avenue just west of Market Street. The elevation is approximately above sea level. It then moves in a zig-zag toward the northwest along Duboce Avenue, Steiner, Waller, Pierce, Haight, Scott, and Fell Streets to the Panhandle Bikeway, above sea level. After climbing 50 more feet, the peak of The Wiggle is reached near Stanyan Street at the peninsular drainage divide, i.e., the dividing point between surface water flowing to the San Francisco Bay on the east side and flowing to the Pacific Ocean on the west.〔Map of The Wiggle (with terrain and elevation contour lines at 40-foot intervals) in Google Maps ()〕 Bicyclists can travel The Wiggle between major eastern and central neighborhoods (such as Downtown, SoMa, The Mission District, The Castro) and major western neighborhoods (including the Panhandle, The Haight, Golden Gate Park,〔MapMyRide charted popular route to the De Young Museum of Art in Golden Gate Park from near Market Street ()〕 and The Richmond and Sunset Districts). ==History== Mint Hill and the hill of Alamo Square on the northeast side are made of underlying serpentine rock, whereas Lone Mountain, Corona Heights, and Buena Vista Hill on the southwest are of the Franciscan chert formation. These hills are the northernmost manifestation of the San Miguel Hills (including Twin Peaks), which themselves comprise the northern tip of the Santa Cruz Mountains.〔Flora of the Santa Cruz Mountains of California: A Manual of the Vascular Plants by John Hunter Thomas, page 3 ()〕 Over thousands of years, the gentle valley bottom was formed through a process of gradual erosion of the soft, crumbly serpentine. This flat creek bed contained, until roads and other construction obliterated them, the intermittent stream of the creek itself and two ponds. As with all such flat valleys, the location of ponds tended to shift, but they were generally located at what is now Divisadero Street near Oak Street and at Market Street from Belcher Street to Reservoir Street. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「The Wiggle」の詳細全文を読む スポンサード リンク
