Lucy Davies, writing in The Daily Telegraph, described her work as recording Wyoming's "inconsequential chores and rituals (washing, shovelling snow, braiding hair) rather than grand events.
Even so, her frank, bold pictures capture the clean-cut thrill of pioneer life, of America's hugeness and scope."
When cowboys and young men in the Civilian Conservation Corps passed through town, Nichols would loan them a camera and ask them to return with photographs.
[3] There are 24000 photographs in Nichols' archive, 16000 of them taken by her, held at the American Heritage Center of the University of Wyoming.
That archive also includes a manuscript for her unfinished memoir, I Remember: a Girl's Eye View of Early Days in the Rocky Mountains.
