In 1853, Lt. Colonel John C. Fremont mapped a new trail and made daily astronomical observations from Green River to Parowan, Utah. In his party of 22 were S.N. Carvalho, artist and daguerreotypist, Mr. Von Egloffstein, topographer, with assistants Mr. Strobel and Oliver Fuller. Fighting bitter cold, deep snow, lack of food, and death of animals, they came to a river, named Fremont by Maj. Powell in 1869, then continued up the valley and over a mountain pass to Parowan in Feb. 1854.
