1901 Map of Mt. Lyell

About this map

Mt. Lyell Glacier stands at the heart of this High Sierra terrain, marking the high-altitude interface of Yosemite National Park and the adjacent forest lands. Surveyed at the close of the 19th century, the map documents a landscape defined by glacial activity and drainage patterns, from the cascading Waterwheel Falls to the high basin of Tuolumne Meadows. Human presence is noted through the early routing of the Tioga Road and established camps like Glen Aulin.
