The steepest logging incline ever built The Yosemite Lumber Company constructed a railroad incline to access their timber holdings on a high tableland opposite
El Portal. The incline, which was the steepest ever built, connected the timberlands high on the tableland with the
Yosemite Valley Railroad located in the
Merced River valley below. The Yosemite Lumber Company built the incline in 1912, which spanned from
El Portal to the top of Hennes Ridge. It featured a 48% grade at the start, changed to a 52% grade for several hundred feet, and then dropped to a 45% grade until reaching the middle of the incline. The last to the summit were the steepest on the line, with a dizzying 78% grade. Loaded log cars were let down the incline as empty cars were pulled up, using a counterbalanced arrangement. The incline had four trestles and two overhead hold-downs. The line speed reached feet per minute, with a handling capacity of about six cars per hour. The incline utilized feet of wire rope pulled by a big steam-powered hoist manufactured by
Willamette Iron Works. The mill was advertised as the “most modern and up-to-date in the entire west.” Logging occurred from April to November due to heavy snowfall in the mountains. The company took pride in its safety record before the first two fatalities occurred in July 1914. The Yosemite Lumber Company encountered challenges during
World War I, with a lack of flat cars and available workers. Nonetheless, the company persevered and shipped six cars of finished lumber daily. They extended the logging railroad to Empire Meadow, which was approximately 15 miles from the incline. In 1919, the company tested a
Climax locomotive, but ultimately returned it due to its inability to maintain a full head of steam. They replaced it with a fourth Shay locomotive. In 1921, the company cut a record 60 million board feet of lumber, added 15 new log cars, and updated some mill equipment. Despite a fire in September that caused significant damage to the bakery and dining room at Merced Falls, the outlook remained positive. By 1923, the company had constructed more employee housing and added a second story to the Yosemite Valley Railroad station. It employed 700 workers and cut over 70 million board feet of timber, setting an all-time record for the company at that time. To fund the construction of a new incline, modernize the mill, and relocate the logging railroad, the company raised $5 million through a bond issue. A crew of 200 men worked around the clock to complete the new incline by the 1924 season. The 8,300-foot incline, which cost nearly $1 million, required more than 400 rollers and had a maximum grade of 68 percent. A second incline was built above it to access additional timber. The main hoist, an electrically operated double-drum system, weighed 320,000 pounds. The incline was double-tracked for the upper half and transitioned to single track for the descent. In 1924, the company set records by cutting 60 million board feet of lumber, followed by 85 million board feet in 1925. At peak times, it employed 500 men at the mill and another 500 in the timber camps, with a daily payroll of $5,500. To generate the revenue needed to meet bond payments, the company operated seven days a week, 10 hours a day. ==Merced Falls sawmill==
