MS-1: Wright Brothers Collection
From 1897 to 1899 the Wright Brothers biked here and observed buzzards (turkey vultures) soaring gracefully above the river valley. In the summer of 1899 the Wrights developed their wing warping theory while watching the birds at Pinnacle Hill twist the tips of their wings as they soared into the wind.
