View photos of the edible plant Pseudocymopterus montanus (Mountain parsley), profiled in Wild Edible Plants of Arizona and Wild Edible Plants of New Mexico.

A passage from Wild Edible Plants of Arizona:

Consider Mountain parsley an important wild edible to know in the Arizona mountains. The entire plant is edible and since the roots are the main part, it provides more sustenance than many other plants.

A passage from Wild Edible Plants of New Mexico:

A small perennial of the Rocky Mountains, Mountain parsley is most abundant in the Sangre de Cristo, San Juan, and Jemez Mountains. It too is found in the Chuskas, south to the Sandias, Gila–region ranges, and Sacramentos.
