Probably best known as the engineer and architect of the Washington Monument (1859-1860), in 1857 in 1857 Ives was "promoted to first lieutenant and was named to lead an expedition up the Colorado River in order to develop potential routes of supply in the event of a war between the national government and the Mormon settlements in Deseret (Utah). Ives's expedition included John Strong Newberry as naturalist, the Prussian Heinrich Balduin Möllhausen as artist and unofficial diarist, and F. W. Egloffstein as topographer. Ives purchased a steamboat in Philadelphia. The vessel was taken apart and shipped via the Isthmus of Panama to California and thence to the mouth of the Colorado River, where Ives and the members of his expedition rendezvoused late in 1857. Ives and his men reassembled the steamboat and christened it the Explorer.
