Julius W. Kaskel appears to have lived in Leadville with his family from 1880 until 1883. During this period he was employed as the manager of Kaskel & Co. for the owners: Caesar J. Kaskel who lived in New York City and one Jacob Michaelis. The relationships are unclear. The clothing business was originally in the Bush-Trimble building which collapsed on April 22, 1880. It reopened a month later at 405 Harrison Avenue which also served as the residence for the family. On May 19, 1882, the Kaskel's bad luck continued then they suffered an insured loss on a building they owned during the Palace of Fashion fire. The retail space at 405 Harrison Avenue was taken over by May & Shoenberg in 1883 although the Kaskels kept it as their final address in Leadville that year.

Julius was active in the community through his participation on the Reception Committee of the Charity Ball held December 14, 1882 and via his election as treasurer of the Leadville Lodge No.51, AF and AM (the Masons) during January, 1883. He also hosted a party in honor of his son David's academic achievements late in December of 1882. On a less happy occasion, the family buried three week old Asher in the Hebrew Cemetery (Block B, Lot 3, Grave 8) on October 17, 1882.
