YOSEMITE Rules and Regulations 1920

VALLEY FACTS AND FIGURES.

The Yosemite Valley was discovered in 1851 by Capt. John Boling, who, with a detachment of mounted volunteers, had pursued hostile Indians into their mountain strongholds. It rapidly became celebrated. The first house, afterwards known as Black's Hotel, was built in 1855. The valley is 7 miles long. Its floor averages 1 mile in width, its walls rising from 3,000 to 4,000 feet. These tables are interesting:

CLOTHING AND OUTFIT.

Reasonably warm clothing should be worn, and persons should be prepared for sudden changes of weather and altitude. Good every day clothes, golf or bicycle suits, are suitable for both men and women for park travel. Wearing apparel, dry goods, boots, shoes, etc., may be procured at reasonable rates at the general store on the floor of the valley. Serviceable gloves and tinted glasses should form a part of one's outfit.

ADMINISTRATION.

The representative of the National Park Service in immediate charge of Yosemite National Park is the superintendent, Mr. W. B. Lewis. A force of rangers assists this officer in protecting the reservation. The tourist season extends from May 1 to November 1, but Yosemite Valley is open to visitors the year round. The address of the superintendent is Yosemite, California. General information may be obtained from him, and all complaints should be addressed to him.
