Geology
The ColoradoYule marble comes from the Leadville Limestone of Mississippian age quarried near the mountain. It was formed by contact metamorphism in the Tertiary period following the intrusion and uplift of nearby granitic Treasure Mountain dome. Yule marble was used in the building of the Lincoln Memorial. The Yule marble quarry is at an elevation of on the west side of Treasure Mountain along Yule Creek. The quality and durability of the Yule marble was questioned prior to the building of the Lincoln Memorial as was the recently opened quarry's ability to provide the quantity and size required for construction.
Origin of name
The original name of the peak was Citadel Mountain. The current name came from an ill-fated French mining expedition described in folklore documented in the 1930s and 1940s. The folklore states that the expedition was organized in the late 1700s by Napoleon Bonaparte, who needed financing to fund his ambitions. The expedition was reported to have consisted of 300 men and 450 horses. They left New Orleans and traveled through Leavenworth, Kansasen route to the Rocky Mountains. The folklore claims that a large amount of gold was discovered and amassed by the expedition near Wolf Creek Pass. The localNative Americans were reportedly initially friendly, but relations deteriorated. In the folklore, the French buried the gold and escaped from the area, pursued and hunted by warriors. One survivor, by the name of Le Blanc, made it back to Kansas. He was the expedition's historian and was reported to have made two maps of the hidden treasure. A later expedition failed to find the treasure. William Yule, many years later, claimed to possess a copy of the original map and explored the area south and west of the mountain. The mountain was named after the legend of the missing treasure.
