Landscape painter, Francis Seth Frost, a Bostonian, made his first trip West in 1859 as part of the Lander Wyoming Expedition, which went into Idaho as well as Wyoming.

This killing had occurred in a meadow near Cedar City, Utah, where Mormon's, allegedly with Indian assistance, had murdered 128 emigrants from Arkansas.

Frost then had his own studio in Boston, and also briefly took up photography.
