John Muir: A Thousand-Mile Walk to the Gulf

Muir left Indianapolis by rail, then crossed the Ohio at Louisville on 2 September 1867 and steered through the big city by compass. Days later he reached the great Mammoth Cave and was surprised to find it so natural: only a narrow trail down a glen led to its door. Today the cave belongs to Mammoth Cave National Park, which protects the longest known cave system in the world.

Precisión del lugar: The pin marks Mammoth Cave National Park; Muir only says he reached the cave by a trail down a glen.

Para el visitante: Mammoth Cave National Park is open to visitors; check the park's own pages for tours.

Heading south through Kentucky, Muir began the ascent of the Cumberland Mountains, "the first real mountains" his feet had ever touched. The ascent zigzagged up a slope covered like a tunnel by overarching oaks. The range is part of the Appalachian Mountains.

Precisión del lugar: Muir's route crossed the range in Tennessee; the pin marks the Cumberland Mountains in general, not his exact path.

Waiting in Savannah for money from home, Muir slept in Bonaventure graveyard, reached by a smooth white shell road a few miles from town. He found it so lovely that he did not wonder a man should dwell among the tombs. He spent six days and nights there, sleeping upon graves. Bonaventure Cemetery can still be visited.

Para el visitante: Bonaventure Cemetery is a public cemetery; visit by day and keep to the paths.

On 23 October 1867 Muir reached the sea; at Cedar Keys he stood at last before the Gulf of Mexico, stretching away unbounded except by the sky. Then he fell ill, probably with malaria, and was nursed in the Hodgson family's house, to whose care he said he doubtless owed his life. The Cedar Keys are a cluster of islands near the mainland, and the town of Cedar Key lies among them.

Precisión del lugar: Muir does not give a street address; the pin marks the town of Cedar Key, not the Hodgson house or mill.

The walk ended at the Gulf, but Muir's real destination came later. After reaching San Francisco about 1 April 1868 and staying only one day, he set off for Yosemite Valley, passing the mammoth trees of Mariposa. Yosemite Valley is a glacial valley in Yosemite National Park, in California's western Sierra Nevada.

Precisión del lugar: Yosemite Valley is a whole valley; the pin marks it generally.

Para el visitante: Yosemite Valley is the park's main visitor area; check current park conditions before you go.
