Help me out. Your link displayed as a blank page when I clicked it. Any translation for chilchin? There is a community on the reservation, Chilchinbito, which translates as " chilchin water(spring). My Navajo is pretty elementary.

The only berry I can think of that is widely distributed in the Navajo Reservation is juniper. There are probably quite a few berry plants with restricted distributions, however.

Most Navajo children I have known are avid coca-cola drinkers; their parents prefer coffee.
