Hey Disco, here in central Oregon we have the Western Juniper, Juniperus occidentalis, and the berries (which are actually not berries at all but cones) are edible. We have two distillers here that harvest the berries for making their hooch! The best time for harvest is late August through early November. I plan on harvesting some this fall and drying them.
More than likely without seeing a picture the junipers in your area are Juniperus scopulorum, Rocky Mountain Juniper. The berries (cones) are edible.
Now for the warnings. All the berries(cones) of junipers are a diuretic. So use sparingly as a seasoning only. Do not eat large quantities of them, especially in raw form. If you have kidney problems avoid using them.
