Do these trees look different than the Rocky Mountain Juniper you just passed?
The junipers growing on this dry hillside are Utah Junipers. They are more common in dry areas than Rocky Mountain Junipers because they require less water.
The foliage of the Utah Juniper is thicker and denser
than the Rocky Mountain Juniper. Its berries are a bit larger, and the turn reddish brown when you scrape the waxy coating off them.
Do you remember the color the Rocky Mountain Juniper berries turned when you rubbed them?
