This is a Rocky Mountain Juniper (Juniperus scopulorum) branch shoot. Above is a 0.5 mm diameter pencil lead for scale. A tree of western North America, some in New Mexico are thought to be over 2000 years old. Northwest Indian tribes have treated coughs and fevers by boiling the leaves and inner bark.
