He worked as a cowboy for a number of outfits, and documented the harsh winter of 1886–1887 in a number of watercolors. Russell was working on the O-H Ranch in the Judith Basin of Central Montana at the time. The ranch foreman received a letter from the owner, asking how the cattle herd had weathered the winter. In reply, the foreman sent a postcard-sized watercolor that Russell had painted of a gaunt steer being watched by wolves under a gray winter sky. The ranch owner showed the postcard to friends and business acquaintances, and eventually displayed it in a shop window in Helena, Montana. After this, the artist began to receive commissions for new work. Russell's caption on the sketch, "Waiting for a Chinook", became the title of the watercolor. Russell later painted a more detailed version of the scene which became one of his best-known works.
